Photo Acceptance - Post Screening (Jalap)

Wed Apr 08, 2009 4:50 pm

Hello,

I'm a bit puzzled. I've got a colour rejection on this old slidescan:

http://www.airliners.net/addphotos/rejections/big/20090408_x1238837585.4294d-aidc_cdg.jpg

Now, colour can mean either a colour cast or a saturation problem.

At first sight, I would agree that this shot looks yellowish but this is contradicted by the colour cast tool I use (in photoshop elements). Using that tool it turns out that both the white fuselage and the black wheels are free of any colour cast. What am I missing here? Is that tool not always reliable? In any case, all efforts I do to get the yellowish colour out results in a cast over the fuselage.

Or is it a saturation problem?

There's a distinctve colour cast, I've adjusted things below. The contrast is excessive too to my eyes and it's also low in the frame.

Thanks Darren, now I know what to aim for.  Smile

The centering issue cannot be resolved since this is pretty much the full frame original slide. Since this is a rare plane I hope the problem in this shot will be within acceptable limits.

Hi

surely the centering problem can be solved. Just cut off the sky above...

Yes, but then we get a ratio problem. This shot already is 1024x683. Question then is which is the worst evil... .

I've also managed to get the colour cast out. Problem was that Elements only lets you select black- and whitepoint while it was a greypoint that did the trick.

This is how it's in queue right now:

I think it looks better  Smile

Colour looks far better now but it's still too low in the frame (centre rejection?) and I'd increase contrast just a little bit.

I'm not sure about the contrast, on the monitor I'm using now the white fuselage already is very very bright, I'll have another look tomorrow on a different monitor.

The centering I expect to get a wildcard since only colour was given as rejection reason. The screeners knew this was full frame so not adding a centering rejection I believe meant that they would accept it with corrected colours. After all, looking at the other shots of this plane in the database it would be a shame to declare this one a total loss because of suboptimal centering.

Yet, I would like to hear some opinions about the possibility of uploading at 1024x670 or 660 instead of the 683 minimum to camouflage suboptimal or plain bad centering.
Look at this scan that I had rejected:

http://www.airliners.net/addphotos/rejections/big/20090409_y1238932829.5244n801pa2_bru.jpg

It was a bad habit of mine in those days to shoot planes a bit low in frame, when you now need to rotate a bit then otherwise very decent shots turn out unacceptible. A real real shame and I'm hitting my head against the wall for this old habit of mine. Going over the top on ratio could save this shot but I don't feel like trying because I've had enough rejections recently...

Hi

I find it really sad, that some of the rejection rules exist no matter what the photo source is like. This results, as is clearly visible in the fact, that there are very, very few pics from older times.
When taking slides, everyone was trying to get the planes full-frame. The result is, that pics that are not exactly centered, and also such that need a rotation cannot be uploaded at all. In this good old times, pictures were made just by pushing the button - and nothing could be done to them anymore.

My slide collection is, in comparison to some others, medium size, and consists of many shots from the 70's and 80's. There are literally thousands of planes, that are not to find at A.net until today, exept for maybe some rather bad quality print scans.
The amount of work to do with scanning slides is so much and the chance to get them rejected for such strange reasons as 'too grainy' are so high, that most of the peolple won't even try.

For my opinion, the rules for these older pics are a bit too hard.

regards

Rejected again  Sad

http://www.airliners.net/addphotos/rejections/big/20090411_i1239436949.6633d-aidc_cdg_bis.jpg

Overexposed, oversharpened and colour again. No mention of centered so I take it the door is still open. This time I did the full edit in Photoshop 7 instead of Gimp + Photoshop Elements. Clearly not my best move ever.

Anyway, I'm getting a bit nostalgic about the good old analog times, digital edits are just not my cup of tea  Sad

Regarding the shots rejected for centering, another solution could be to crop a part of the plane out so that centering no longer is impossible, like I gave a quick try here:

http://users.telenet.be/janentine/n803pa2_gva_tris.jpg

I know this one would be rejected because soft but less extreme crops might make it like that. It would break my old-school full plane full frame sideview shooting heart though...
