Recently picked up a Rollei P350A for $40. Love it. Prefer it over a newer Kodak Ektagraphic III I have.

What do people do with storage? I keep my slides in sleeves, but for ones I want to project now or in the new future, I have them in my 80/140 carousels. With the straight strays what do you use? I noticed Adorama carries a carrying case that holds 6(?) straight trays... looks handy.

I recently came into possession of my dad's old slides from the 60s and 70s, and my aunt just found a box of old slides of my grandfather's dating back into the 50s (I think). Slide projector research is on my list of things to do! I also bought a carousel and holders at a garage sale this past weekend for $1... LOL

Agreed, we need such a forum! In the last few months, I have acquired a Pradovit CA 2500 and Color 250. These projectors are built like tanks. There are many choices regarding lenses and condensers, but info is hard to find. I also have straight trays, and means to mount slides into glass carriers (Leitz Dia Proloc). With digital madness in full swing, people are throwing this stuff into dumpsters. For shame. :)

What are you guys using for projector stands and screens?

Hmmpf. I see we've been relegated to the miscellaneous forum. Leitz projectors thrown in with the bags and cable releases.

I use Ektagraphic projectors, and recently picked up a Leitz RT-300. I also use Hasselblad PCP-80.

I got the Leitz RT-300 after reading a few posts around cyberspace, that it has a whiter light than the Kodak projectors. It uses a dichroic mirror rather than the greenish heat absorbing filter of Carousels, Ektagraphics, and most others. I'm finding that when I do a two-projector dissolve show, with one RT-300 and one Ektagraphic, I don't notice any difference in color cast between them, as the two machines alternate. So maybe it's not a big deal.

The RT-300 runs a little quieter than some of my old Ektagraphics, that like to rattle and clatter. That's good. Two or three of my Ektagraphics (I have six) are just as quiet as the RT-300. I can change a lamp in the RT-300 from behind the projector, without having to flip it upside down or disturb its alignment. That's good. The projection lens has to be inserted into a tunnel. This makes it hard to use my Schneider PC lenses, and impossible to use my large Golden Navitar lenses. That's bad. The RT-300 is larger and bulkier than my Ektagraphics. If I were to switch to all RT-300, I'd build new stands for them, or modify the ones I already built.

Any comments from other RT-300 or Ektagraphic users?

How interesting. I just donated 20 120 rotary trays to a local thrift shop as I didn't have a projector that would take that large a size. I got them in a large lot off ebay some years ago. They didn't fit my Vivitar projector. I did keep the smaller rotary trays and the straight trays. I need to do more slide photography. I always loved projected slides. I hope digital matches that some day. (runs into bunker, closes vault door)

Hey--thanks for this forum!!
I have RT-300s, which I believe were made by Telex for Leica.
Telex did modify the internal optics for Leica.
I have 2 and they do not autofocus very well.
Most of my slides are viewed with an Ektagraphic IIIA, a Leica Color 250 and a Xenon 750.
The 750 is REALLY bright and white!
Thanks again!
Paul

Rob-F

Xenon 750: is that a projector? With a Xenon lamp?

I forgot to mention: I plugged my Kodak Ektagraphic programmable dissolve control model 2 into the RT-300 to test compatibility. The Rt-300 started cycling the tray around continuously, even though I was not pressing any buttons on the dissolve control. It does this even with the dissolve box turned off and unplugged!

If I plug in my entre 7903 dissolve control, the projector runs normally.

If plugging in the Kodak control makes the projector advance, then the Kodak box must be wired in a way that is incompatible with the projector. That would have to be true. However: the entre box is compatible with both the RT-300 and the Ektagraphic. And the Kodak box is compatible with the Ektagraphic. (Well duh, Kodak made them both.) Now, you would think that if both controllers work with the Ektagraphics, and one works with the RT-300, then the other one should work, too. But, no. So I will have to trace out all these circuits to see why the Kodak unit won't work with the RT-300.

I spent a few years as a field engineer for Emerson Electric. Before that, a radar tech in the USAF. I've seen weirder things. There's always a reason.

I bought a P600 a couple years ago and fixed up a square of matt finish foam board as a permanent screen.I picked up that tip over on photonet.
Always thought that the disadvantage of slides was the setting up.
Now I don`t have to.
The slides (dating back to `73 ) are housed in Leica slide trays.
Mostly K25/64/200.

Rob-F--the Xenon 750 uses a modified Ektagraphic IIIA on a base that contains the 750 watt Xenon lamp and the lamp's power supply.
Really makes for a bright, white image.
Here's a link:

Okay, well after seeing this thread I finally just went over to ebay and bought a slide projector. I got a Vivitar 3000AF for $15... LOL!

It came today and it works perfectly. I recently came into possession of my dad's old slides (he passed away in 2001) so we're going to have a view party now!

And my aunt just recently discovered a box of slides in her basement with at least 500 slides from HER dad (my grandfather)... so another viewing party there!

I'm so happy right now :)

BTW... my 16yo daughter thought the slide projector was about the coolest thing she ever saw. She wanted to know why they aren't popular anymore... LOL. Sometimes I swear she was born in the wrong decade. This is a girl who still types (on a typewriter... not electric) letters to her friends after she begged me to buy her one at the thrift shop.

I'm sure the Vivitar isn't the best projector of it's type... but it will get the job done!

What are you guys using for projector stands and screens?

Here's how I hold up my projectors. It's all home-built from plywood and particle board. This is how my setup looks at the moment. It changes as I experiment or want to look at a show that calls for a change in setup. A difficulty with multiple projectors is that only one of them can occupy the ideal zero degree position: not having to be aimed up or down, left or right. This can be solved with perspective control lenses. At the moment, the top projector in the center stack is wearing a Golden Navitar PC lens, and the lower projector has a Schneider/Isco PC lens. The left and right machines at this moment have Schneider Vario-Prolux 70-120mm f/2.8 zooms.

I'll show what I use for a screen later on.

When I was kid, Cinerama, CinemaScope, VistaVision, and Todd-AO all came out, followed by UltraPanavision70 and SuperPanavision70. I was always fascinated by the idea of curved screens, and I've built a few. As a kid I decided that when I grew up, I was going to show my slides on a big wide screen. This one is in my basement. It's 8 feet wide. I built a curved wood frame and used foam-core board as the screen surface.

That's quite a decent set up. Care to comment on the PCP80?

Rob-F
06-28-2010, 08:40
The PCP80 in the picture is one of two I have. This one came from the Royal Museum, I believe in Toronto--by way of eBay. It runs very smoothly and quietly. The perspective control allows me to mount the projector lower than the stack behind it, while still projecting a top-quality image. It has a connector in back for remote operation, but the plug style is unlike those I usually see on projectors.

My second PCP-80 came with a remote control for slide changing and focus. It has a connector on the back that is more similar to those I've seen on other projectors. I would probably use it more, but it makes noise while changing slides. I think it's coming from the rubber idler, but I haven't tried to find a replacement for it yet.

Both projectors deliver a bright, high quality image, easily surpassing 35mm, even if the slides were shot with Leica Aspherical lenses. Size matters. The images are shot for wide-screen projection, using either my XPan, or else shot in the Hasselblad and composed and later cropped for the 2:1 aspect ratio I use. It's not quite IMAX, but it is a lot like 70mm Super Panavision for image quality: just about the same film size.

Another thing I like about the PCP-80 is that a spare bulb can be brought into position instantly should the bulb fail during a show.

Although they are branded as Hasselblad, these projectors were actually built by Zeiss, and have Zeiss nameplates underneath.

I'd like to use my two PCP-80 machines together for a dissolve show, but I'm sort of out of room at the moment to be able to set them both up. And I would need a second 75mm lens--not easy to come by without a projector attached.

And then... when you want to project or view the slides? I'll be quite a few years I think before 20+ Mpixel digital projectors are widely available. 4096 x 2400 pixels is probably the best anyone here might currently have access to and most people would probably be limited to 1080p or even 720i. There is no beamer or LCD panel that can compete with the image reproduction quality of a used $5 slide projector.

Remember also that your slides are your archive. They are your most effective and cost efficient means to archive your photographic images. Scans are an adjunct but not a replacement.

Its for these reasons (and a few more) than even many digital cognoscenti have their images rendered to film.

I dunno. Are people really that excited about slide projectors?

I gave away my last slide projector a decade ago because I hadn't used it in 20 years. It was a nice Kodak Ektagraphic Carousel fitted with a Leitz lens. Lovely thing, sat unused in its case for so long I thought it might be frozen up. But it worked perfectly when I pulled it out.

For thirty years a shot mainly slides .
When I came back to photography about ten years ago I carried on from where I left off shooting K64 and Fuji.
I bought a Leitz projector with a colourplan lens ,fixed up a white foam board permanent screen ,couldn`t have been happier.

Eighty percent of the slides a reloaded into trays ready to go.
I`ve scanned them all ,of course, but its not the same.

Kodak binned K64 as we know and the cost of shooting the remaining brands just became too high ...for me.

Shame ... its odd that there hasn`t been a renaissance as it other types of film media.

I would love to see a projection/slide category. I shoot ONLY slide film (E6, DR5). I live all over the world (moving on average about every 3 years... Turkey being my last destination for 4 years) and most of the countries I go don't even have slide processing available. But slide projection is such a beautiful art that I have always been fine with waiting up to a year to get back home and having them developed. Talk about not needing instant results!

I have a Leica P600 with Colorplan projector and keep all my slides in two separate locations (one with me and another with my sister) just in case one batch gets messed up... it's like my backing up files i guess.

Rob-F
11-08-2014, 20:53
I have a Leica RT300, but my multi-projector dissolve shows are run on Kodak Ektagraphic projectors, because I use large diameter wide angle lenses that don't fit the RT-300. The latter has a deep well or tunnel into which the lens goes. The tunnel makes the use of some lenses difficult or impossible. I could cut it back, as it's only sheet metal, but first I need to solve some compatibility issues with dissolve controllers that work great with my Ektagraphic projectors, and not with my RT-300.

Let's get the projector forum up and running!

+ 1000 !!!

It is urgently needed!
Slide projection is offering the best quality for bigger enlargements at by far the lowest costs.
This medium is unsurpassed. You cannot get this performance with digital media or with prints from negative film.
Brillance, colour, contrast range, resolution, sharpness, the "three-dimensional-effect" you get with an excellent projection lens:
All at best quality with an excellent slide projector.
And there are so much excellent slide projectors available, both used and new!

This forum would benefit a lot with such a subforum ("competitor" apug does not have one ;) ).
But the German language aphog.de has one, a big success, lots of traffic, very good information, and it attracts more forum members than other subforums there.

A slide projection (including all other relevant topics like slide mounts, screens etc.) subforum would improve rff significantly.
And now, with the new interest in reversal film encouraged by Film Ferrania, Adox and Rollei (for BW slides), it would be the right supporting signal.

Please, Mr Gandy :).
And thanks in advance!

Yes, I am. I am projecting both 35mm and medium format (4,5x6 and 6x6).
I am using a Rolleivision 66 with the marvellous Schneider-Kreuznach AV-Xenotar 2,8/150.
Highly recommended!
Much much better than the P11.
And as you are not satiesfied with the "intensity", the Rolleivision 66 has better brightness and brillance compared to the P11.
The Rolleivision 66 AV is then even a little bit brighter (new condensor system) compared to the Rolleivision 66.
These both projectors are very cheap on the used market.

I like the idea of a subforum on the topic of slide projectors.

It may also be useful to include topics like the scanning and display of slides on large screen televisions as well.

As nice as a projected transparency looks, I feel a properly scanned slide or negative, post photoshop, can look even better, and not as hard on the slide.

I use the Hasselblad PCP-80 with the 75mm wide-angle lens to project MF slides I have composed to, and then cropped to, a 2:1 aspect ratio. I modeled it after the look of 70mm Panavision (which is actually a little wider, at 2.21:1). My wife says it's just like being there.

There are a lot of photographers over at photo.net, so it might be more fruitful to do a search over there. They even used to have a dedicated slide projector forum, but it seems to have gone the way of all things. Pity. Still, one can access a lot of information there.

http://photo.net/bboard/forum?topic_id=23&category=Slide+Projection

I can testify to the (admittedly spendy) all around goodness of the Hasselblad
PCP 80 for 120. There are lots of good choices for 35, but search over at photo.net.
Not allowing a slide projection forum here was a large lost opportunity to promote a still valid art form IMO. (Notice I said valid, not viable)
Yes, nobody does it so it is "dead" in the same way that illustrated manuscripts are dead. But, as someone else said, when was the last time 100 million people were right about anything.

I've had no experience with the Reflecta, so I can't help there. About all I can add is that my RT300 Leitz is nicer than my Ektagraphic Pro, or whatever they call it, but not by that much. Both those were brighter and sharper than my garden variety Kodak Carousels.
I guess that isn't much help, but it is the best I can do from personal experience.

Congrats on getting the Diamator up & running! Still, a dual format projector is an interesting idea. It has a parallel in motion pictures. When 70mm movies came out, Century made a 35/70mm projector, so that theaters could show the two formats interchangeably. A dual format projector could be useful at home, too!

A projection subforum makes a lot of sense. It could be set up to include all manner of displayed image systems (large screen digital, digital projection, analog projection, ???).

I used to project slides rather often. But with digital and all..... Anyway, I kept my projector (Kodak carousel 650H or something like that) and just a few trays. I donated the remaining 10-20 carousels to the local thrift store. I needed the space and I haven't shown slides for a while now.

Now, I actually like the idea of projecting again from time to time (obviously, I kept the projector and a few trays), but I'm not enamored with the quality of my projection. I'm fairly certain this is because of the lens. I've never attempted to locate a better lens for my projector because I don't know where to start.

Are there standard "mounts" for projector lenses? Can I actually use a high quality lens on my lowly Kodak 650H? Assuming I could find such a thing, are there nice Schneider, Zeiss, Leitz, etc. lenses that I could use instead of the Kodak whatever that came with my projector? What would I look for. Where to start?

Hmmm.

I've recently been getting back into taking and viewing slides and I'm really enjoying it. There's something quite magical about looking at slides on a lightbox. They look like precious jewels to me.

I bought a Pradovit CA2500 with the Colorplan lens for 35mm, and a Rollei 66 projector for 6x6. I don't have anything to compare them against, but the projected slides look amazing through both systems. In some ways the 35mm slides are most impressive because there is so much detail and so little grain. Obviously, the medium format slides even more so, but I'm used to those already looking very detailed.

Shooting slide film for projection is having a big positive impact on how I take photos. The higher cost per shot means I'm a little more careful about my subjects, which is resulting in a very high hit-rate per roll. I shot a roll of Velvia on holiday and out of 38 photos, I've marked off 30 for mounting. And believe me, given the time it takes to mount them (I'm scavenging mounts from old slides), I'm very selective. The inability to crop means my framing has improved, and I'm now using a spot meter and learning to use the zone system properly. It's a fantastic learning experience and definitely pushing my skills up a notch.

Next project: learning to shoot and process my own B&W slides. Bring it on!

Oh and yes, a projection/projectors sub-forum would be great.

You could do an entire class on the range of body language from just this one photo.
I like it.

From left to right, it's like the three stages of relaxation during an evening. :o

You can do it with any black and white film. However, for best results you need to pick a film that has high contrast, otherwise it will be ultra flat. I'm so keen to try it out but I still haven't gotten around to it. Here're Ilford's instruction on how to do it.

There are tons of threads over on APUG. You can use a lot of different films and there are a few options for reversing the film, either chemically or using light (the Ilford method). I'm going to try the chemical process first using 'Iron Out'.

By all accounts, and amazingly, reversed B&W film seems to have even more detail than in it's negative form. More details about the films that work well can be found on this site:

These guys are setting up their lab after a move, so you should be able to get slides created commercially again soon.

A projection subforum makes a lot of sense. It could be set up to include all manner of displayed image systems (large screen digital, digital projection, analog projection, ???).

I used to project slides rather often. But with digital and all..... Anyway, I kept my projector (Kodak carousel 650H or something like that) and just a few trays. I donated the remaining 10-20 carousels to the local thrift store. I needed the space and I haven't shown slides for a while now.

Now, I actually like the idea of projecting again from time to time (obviously, I kept the projector and a few trays), but I'm not enamored with the quality of my projection. I'm fairly certain this is because of the lens. I've never attempted to locate a better lens for my projector because I don't know where to start.

Are there standard "mounts" for projector lenses? Can I actually use a high quality lens on my lowly Kodak 650H? Assuming I could find such a thing, are there nice Schneider, Zeiss, Leitz, etc. lenses that I could use instead of the Kodak whatever that came with my projector? What would I look for. Where to start?

Hmmm.

I projected 35mm slides for years in teaching, and became acquainted with the different qualities of projectors and lenses. Both Schneider and Navitar made high end lenses for Kodak Carousel and Ektagraphic projectors, and they tend be larger f stop lenses, 2.8 versus 3.5. I bought a Schneider zoom lens that provides far higher resolution, brightness and minimized light fall-off in the corners than the normal Kodak lenses. But Kodak also made a more expensive and higher quality range of lenses - you should be able to find this information, and I suspect the very good lenses are available for reasonable prices. They really make a difference.

Thanks for the motivation. I suppose a round of "internet research" is in order. You mentioned one characteristic of my current lens that drives me nuts.....falloff (or vignetting). But also sharpness/resolution. I'm guessing prime lenses are superior to zoom.

Last night I peeked in the closet. Yup, the projector and a few carousels are still there, along with a Da-Lite screen (but my flat white wall seems to work better).

I love projecting slides. Straight-tray projectors are popular in NZ, so I decided to concentrate on Leitz models. I mostly use a Pradovit P150 with a Colorplan-P2 90mm f/2.5. The Hektor-P2 85mm that P150's come with has so much field curvature that it's really only good for keeping out dust.

I sometimes use a pair of Pradovit Color 150's also with Colorplan 90's - one is an early type with the earlier 46mm polished alloy tube, another with the later black 42.5mm tube.

I prefer the quietness of the P150, but the Color 150's are superb quality machines and the earlier Colorplan 90's have a flatter field than the later P2 type.

I have a Pradovit C2500 with a Colorplan 90 and Elmaron 200mm but no hand control. It's a solid commercial-grade machine, but noisy. They were the standard slide projector at universities here for decades.

From the early 1960's I also have 4x Pradovit-n and 2x Pradovit-f. One Pradovit-n belonged to my father.

There is also a late 1950's Prado 500 with Hector 2.8/250mm & Dimar 4.0/25cm, plus a Prado-SM with a 2.5/12cm Hektor. The "Pradoseum" site has good pages on the ancient stuff:

http://www.pradoseum.eu/englisch-version/schauraum-en.html

The early Pradovit-n's are a thing of electro-mechanical beauty with the lovely snick-snick of the slide change mechanism, but the 12v tungsten bulbs are pretty dim compared to any modern halogen projector. The ancient Prado's are brighter, but run at frightening temperatures.

For medium format I have a Noris Trumph Halogen and a Rollei P66A. The Rollei at least takes 6x6 slide trays.

I used to shoot K64 & K200, but unfortunately Kodak decided otherwise. Perhaps Kodak's recent change of heart with regard to the profitability of film production will extend to re-introducing Kodachrome?

Their recent statement to the Times of India talked about promoting the "archival" qualities of film and Kodachrome is the only material to meet that criteria (under certain conditions).

If you are on a budget I would recommend getting a Leitz Pradovit Color 150 or 250 with the superb Colorplan 2.5-90mm lens. Many have survived and Leica can still fix them.

Any of the more modern Leica units, i.e. the P150, P300 or P600 would also be good, but you pay a lot more money for them. You can also find "IR" versions of these later models which is handy if you like to walk around the room when showing slides.

I have a Leitz CA 2500 for 35mm and would like to find a good quality projector for MF 6 X 6.

If I can locate a good projector, I intend to start shooting Velvia transparency in my Hasselblad 503CX.

Doing some research shows that although no one seems to mount MF slides any longer, actual slide holders, both glassed and non-glassed, are available from a larger eastern photo store.

Yes - I would be interested in a Projector Forum.

I have used both the Hasselblad PCP80 projector, and a Rollei MF projector. Both are good. The Hasselblad has a perspective control lens, and its rotary tray has a larger capacity. The Rollei takes a more compact, easier to store tray.

One of these days, maybe the mods will see their way clear to our own forum!

I have the big brother of Color 150, the Color 250, and they have the rock-solid construction of that Leitz era. The C2500/CA2500 family is higher end, but not better built. I'm fortunate to them both. As for the noise, well, it comes with the territory. :)

Help! So far I have found Kodak lenses for Carousel type projectors with seven different names:
Slide Projection
Ektanar C
Projection Ektanar
Projection Ektanon
Projection Ektagraphic
Ektapro Projection
Ektapro Select Projection
I know the Ektapro Select Projection is the best, but I don't know the quality order of the other lenses. Can anyone arrange thus list in order of quality? If you can, thanks.

I have no financial connection to this person outside of sending him money now and then, but have found him to be helpful and knowledgeable in the past.
He seems to be a good source of information along the lines of what lens is better than which other lens, and I have felt that he has been honest with me regarding all things projection.
FWIW

The "C" in "Ektanar C" is for (C)urved field. This lens is used to correct for the curvature of a slide that has "popped" on account of the heat from the projection lamp. "Popping" is a normal thing when projecting slides that are in cardboard mounts, or glassless plastic mounts. It is due to the unequal expansion, from heat, of the emulsion and non-emulsion sides of the film. Glass mounting prevents this. For other mounts, a "C" lens may help to maintain focus across the field.
