I generally take the photos I like the best, prepare them, and put them on my photo website. I looked at those photos and discovered that there was only one photo from May 2005 that I had judged was worth putting up so I felt relieved that I apparently didn't lose a bunch of good photos. The trouble was that the one photo is a photo I like a lot. All I have is a 640x507 pixel jpeg version of that photo that I took with my 6.3mp Canon 300D that made 3072x2048 pixel files. I had apparently cropped it a bit, possibly made some small adjustments, and used a bit of unsharp mask before resizing, and saving a medium quality jpeg for the website. In those days I was using Paint Shop Pro X. The small jpeg I have has no EXIF since PSP X would strip it off when you saved. Basically this is almost a worst case scenario for trying to sort of save a photo.

Canon 300D + Sigma 18-125mm f3.5-5.6

I tried this 640x507 photo using Gigapixel AI 5.5.1. I enlarged 4x to match what I did using the other methods. Fortunately, I still have the folder with the results. With Gigapixel I tried Standard, Lines, Low Resolution, and Very Compressed using Auto. Then I tried adjusting myself. In all cases the results are not as good as the free online place. So, the free online is still the best, but Gigapixel AI Standard is next. Frankly, I am surprised.

I had wondered if the free online place was actually using Gigapixel AI to do the uprez, but it looks like they have their own software and it is superior (at least for this small photo).
