Scaning and shapening

[Assaf]

Good evening friends,

I have to scan many 35mm BW pothos. The final results should be 900 pixels wide, for online galleries, and 1280 pixels wide for full screen presentation.

I wonder what's the best combination for acheiving best shapness:

1) What is the scan resolution you use? Final resolution or higher and then you reduce it?

2) JPEG, TIFF or DNG?

3) In what phase do you sharpen? Scan software, PS raw converter? PS? Do you sharpen at all?

I use Epson V700, Vuescan and CS3. I must admit that my minilab automatic color scans (using Noritsu) look much sharper and more vivid than the ones I do at home. However, I still prefer scanning the BW negs myself.

Thanks for your answers and take care
Assaf
