Restoring old photos

I recently started remastering some of my old pics. hese were shot on a Canon point and shoot, 4m. I opened these in Adobe Bridge and opened them up as RAW files and adjusted most of my parameters there. Then when I opened them in Photoshop, all I had to do was tweak the light level and save at max resolution. Viola- a 19kb 72ppi image becomes a 150kb image at 240ppi. It's like lifting a veil of gauze away.
