+ | * 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 | ||

- | I. Orientation (if necessary) | + | === 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 | + | |
- | II. Crop | + | * Use //Select// tool to outline image with a small border |
- | Use Crop tool to outline image (when outlined, confirm image orientation) | + | * Right click to //Free Transform// - grab corner & rotate as needed (Choose another tool to make changes permanent) |
- | Make certain that no border areas are left | + | * If needed, hit [Ctrl + “] to view grid over image |
- | If necessary, crop slightly inside image if nothing significant is lost | + | |

- | III. 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 | + | |
- | IV. 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 | ||
- | V. Background (if necessary) – for objects on a white or colored background | + | === Crop === |
- | Use Magic Wand with Paint Bucket tools to turn background black | + | |
- | VI. Dot-matrix or visible patterns | + | * Use //Crop// tool to outline image (when outlined, confirm image orientation) |
- | Use Filter – Gaussian Blur tool | + | * Make certain that no border areas are left |
+ | * If necessary, crop slightly inside image if nothing significant is lost | ||
+ | | ||
- | VII. Sizing – this should be the final step | + | === Color correction === |
- | 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 | + | * //Auto-levels// – sometimes works, sometimes doesn’t |
- | Use Save As to save image to Corrected folder on the O: drive | + | * //Auto-color// or //Auto-contrast// independently |
- | Then move the original uncorrected image from Needs Correction folder to N: drive | + | * //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 | ||
