Image Correction Guidelines

General stuff to remember:

  • 5 minute rule – if it looks like it will take over 5 minutes to correct, skip it – we’ll rescan it
  • If you just can’t get it right after your best effort, move to another and let Brian or Steve know
  • If you encounter duplicates while correcting, consult Brian or Steve

Orientation (if necessary)

  • Use Select tool to outline image with a small border
  • Right click to Free Transform - grab corner & rotate as needed (Choose another tool to make changes permanent)
  • If needed, hit [Ctrl + “] to view grid over image

Crop

  • Use Crop tool to outline image (when outlined, confirm image orientation)
  • Make certain that no border areas are left+
  • If necessary, crop slightly inside image if nothing significant is lost

Color correction

  • Auto-levels – sometimes works, sometimes doesn’t
  • Auto-color or Auto-contrast independently
  • Color balance for overall color adjustment to image (Variations for rough idea of what direction to go with adjustments)
  • Selective color for working with specific colors

Dark/Light adjustments

  • Brightness/Contrast – gives a rough adjustment – sometimes works, sometimes doesn’t
  • Shadow/Highlight – better control – Shadow lightens dark areas & Highlight darkens light areas

Background (if necessary)

  • for objects on a white or colored background
  • Use Magic Wand with Paint Bucket tools to turn background black

Dot-matrix or visible patterns

  • Use Filter – Gaussian Blur tool

VII. Sizing – this should be the final step

Use Image Size window to see raw size
Check that longest side is approximately 3100 pixels
Change dpi to 300 (if necessary)
Reduce longest pixel dimension to 3072 – never increase pixel sizes
	If longest dimension is under 3000, consult Brian or Steve

VIII. Saving

Use Save As to save image to Corrected folder on the O: drive
Then move the original uncorrected image from Needs Correction folder to N: drive
