Oh, it seems like I veered a little bit off topic by giving you my opinions, oh well.
The main point I was trying to get across is "stop whining about airliners.net standards." You've all said it yourselves - you love high-quality sideshots. OK
then. Airliners.net is full of low-to-medium quality sideshots, so now the standards have been raised. You said it yourselves - collectors want HIGH QUALITY. So that's what you're up against. By uploading sideshots and documentary-style, collectable pictures to airliners.net, you're competing against some of the best documentary-style aviation photographers. If you want to run away from that competition, go ahead and "leave" airliners.net and yank your pictures off. But, if you want to continue to compete for acceptions here, you'll have to put forth extra cash to buy new equipment to make your images top-notch and stop whining
That's the main point of my post. It's hard to argue with what I just said; you all just said it above.
Basically, if you upload documentary-style photos, know that there is a lot of competition in this arena. So you can buy new equipment and not whine about having to do it, or you can change your style of photography. Either choice is great, granted that you don't whine about it.
