This thread is very useful...thanks. Two more questions to add to it:

1) Relative to shapening, what's the best practice for when the file first opens (in this case a B&W drum scan - 6x6 neg) in Adobe Camera Raw? There is a "preset" of sharpness already attributed to the image. Should I wipe this out to zero and proceed to Photoshop after making other adjustments. OR... should I keep the basic sharpening that is attributed in ACR, or should I in fact do more sharpening in ACR.

2) When converting to 8 bits prior to printing, does my work flow need to be: convert to 8bits, then convert to RGB...OR by JUST going to RGB mode, does that automatically convert my 16bit file to an 8 bit.

Thanks, once again.

You don't gain anything by taking a drum scan through ACR. It and Lightroom are meant for digital camera raw files. If you're using PhotoKit Sharpener or something similar, go to ACR prefs and set Apply Sharpening to Preview Images Only. That way they are not applied to your exported images and you can use your normal sharpening workflow.

The RGB conversion does not alter your bit depth. If you're done editing and need to convert to RGB, you'll get a smaller file by dropping to 8bit first. Just remember to keep a 16 bit file on archive so you can go back to it later on for edits, if necessary.

What will a B&W drum scan from a negative come into photoshop as....A greyscale image?

Thanks for the advice, I will pick up that PK plug in after reviewing it on the website.
