A basic workflow for your images after scanning would be:

• Check media to make sure there are no disc errors, and burn a second copy for your archives. (If there are any disc errors - let us know ASAP and we can reburn your scans - they are on our server for a month after your scanning job).
• Crop the image to the desired crop.
  
• Set the black and white points using a curve adjustment layer and make global contrast/colour adjustments if required
  (scans of positives will generally be very close to spot on, scans from negatives will almost certainly need a bit more work as negative film is such a variable material).
  
• Clean the background layer of any remaining dust and scratches
• Use layers/layer masks to make localised adjustments if required
• Save the master file as a PSD or TIFF file and burn twice for safe keeping
• If you would like someone to do this work for you please contact us and we can do this for you.
  

To prepare the master file for printing:

• Load your master file
• Soft proof for your printing process using an accurate ICC profile (e.g ours for our printing service)
  
• Make any final adjustments using the layers
• Flatten the image
• Size to the appropriate size and resolution for oyur print process (e.g. ideally 360 PPI for prints at Image Science)
  
• Sharpen (be conservative, the Imacon is a naturally very sharp scanner!)
  
• Print!
