How would you make this better with CS4 (Photoshop 4) or whatever Photoshop version you have?
It's a print from 1945, my father at Pearl Harbor.
What I did was to photograph it with an iphone, then upload it to my laptop, and I used Win7 photo editor to sharper, increase contrast, crop, and remove noise.
What else would you try to make it sharper and bring out more details?
