I wonder if anyone out there is prepared to give me a bit of help with jaggies after downsizing. I am not sure if I am at all going to try to upload the result, but would be extremely grateful for pointers.
I took this photo of Lauda Air 737-8Z9, OE-LNP at Kef on 26.07.05. With 78 photos of it already in the database there is not a real need for an additional one. But I would like to learn something from trying to edit this one up to an acceptable level. I shot RAW on a Canon 20D with a 70-200 2.8 lens 1995 model, which makes it into appr. 100-320 on the 20D. The weather was great for photography, but when I got back I found for the first time in my experience at Kef that I had a real problem with heat haze up there. That might be part of the problem. I used the JPG file that the camera saves for these trials instead of extracting e.g. a TIF file for editing. That might also be part of the problem
Here are links to four versions of the photo. The original full size, but rotated and cropped file. I did not use USM for it, just the sharpening tool on lettering and some edges. I used levels and got rid of the flat areas to the ends and darkened it a bat with the middle slider. This is the result.
a 3105 pixel wide file 3.3 MB
I then downsized it to this
the usual 1024 pixel wide file, and the fuselage stripes show a lot of jagged edges.
I then tried a downsizing the original to 1500 pixels with this
and the edges are not as jagged.
At last I thought why not try half size, and this is the result.
Now any thoughts about the half size photo, and most importantly, any pointers as to how to avoid the jaggies when downsizing to 1024?
Hope some kind soul will see fit to point me in the right direction, even if the photo will never be uploaded.
