Hey i think you have a great artistic flair in the pics but the quality isnt as great.
I like the pic with the front of the AF747 and the 737 about to land, the quality isnt real good but i think it shows an artisic talent. I also like the CO DC-10, its centered, shows the whole plane and its neat. BUT, first of all, it looks like you were a ways away from the plane and used a zoom lens (nothing bad about that, just a guess) and there are some faint glares on the pic, one that goes horizontal across the pic right under the plane, looks like windows maybe?? also one on the left side up and down.
My opinion (and only that
) is that you can re-scan, but the problem is probably with the original picture. What kind of film did you use? that could be a problem
Anyway, im only responding because i think you have a good knack for airline photography but the ones you posted need just some help. Of course i would still take a few good ones and try and rescan and upload...
