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 your supervisor know
- If you encounter duplicates while correcting, consult your supervisor
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
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 your supervisor)
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
