Help With This Rejection Please.

Tue Oct 10, 2006 4:45 pm

Hi all,

This was rejected for quality and grain

http://www.airliners.net/addphotos/r.../big/20061009_BBJ-737regN836BA.jpg

My guess on the original problem is that the shot was taken with a F/5.6 aperture, which caused some areas to be slightly jaggie. Does this sound correct when looking at the shot?

I thought the grain rejection was due to USM on the entire pic, but when I tried to do everything but the sky I didn't see a big difference, and I could not get the wand tool to stay out of the plane area, so as a result a little piece of the top fuselage was not sharpening :/
My skills at CS2 are not that good, and I am having trouble removing jaggies w/o spending a rediculous amount of time. After reading some tutorials I have still not seen much of a difference. (I don't understand the process of removing the jaggies after using USM? What tool do I use with CS2 after I have USM'ed the duplicate layer?)

It would be nice if this shot could be fixed as this plane is not currently in the DB. Does it have a chance?

Thanks for any help.

Hi Kevin,

Nice catch there. Overall I think the image is soft. What lens are you using? If f5.6 is the widest your lens goes this my have caused the softness too. Is this a heavy crop of the original file? I think it can be saved with some selective sharpening.

Hi Kevin!

Nice shot you got there!
But I gotta agree with the rejection; you got some small issues (soft, overexposed, oversharpened, jaggies) which led to the quality rejection and the sky is indeed grainy.
However I think the shot can be saved with some good editing.
What you need to do is use layer masks so as not to edit the picture as a whole; for instance if you like to sharpen the plane, make a duplicate layer, then sharpen the picture, put on a mask layer and then unmask (sharpen) the plane with the brush tool and merge the layers thereafter; sounds complicated but is very easy once you know how it works.
That way you'll only sharpen the parts of the picture that need it without sharpening areas like the sky which don't need any sharpening and will ruin the picture as they get grainy when sharpened.
Removing the jaggies works the same way but instead of sharpening after making the duplicate layer you'll have to use a softening tool.
Here's an interesting thread you might wanna read to get a good idea on how to use masks: Using Actions/Masks...My Tutorial With Links! (by JeffM Aug 31 2005 in Aviation Photography)

Have fun!

It was shot with a and 100-400 L IS. I thought that the aperture setting was probably my main technical mistake when shooting, but I wanted to confirm?

I only cropped out about 5-10% of the original. I have the RAW if anyone wanted to take a look at it.

thanks for the link Thierry! I will try this out after work.

Kevin,

It was a great day weather wise when you took that picture, no need for f/5.6, you should be looking at something like f/8 or f/11 and 1/500 of a sec.
