Photo Acceptance - Post Screening (Emmerson)

Tue Apr 28, 2009 6:18 pm

The following rejection below (El Al 777 out of LAX) was received for jagged edges/oversharpened. I accept this as jagged lines are clearly visible on the blue paint lines.

My question is this....how can these kind of jagged edges be avoided without some form of photo manipulation (i.e. smudging/eraser tool) after resizing down to 1024px territory....as the resizing process itself creates jaggies in elements prior to any sharpening applied !!! ? (p.s resample option for resize was bicubic not the sharper option).

The RAW is nigh on perfect so I'm tempted to redit this and submit as a 1600pix wide as the jaggies are not then an issue. The advice on 1024 being best quality to upload at can be a bit of a trap in my opinion depending on the aircraft livery and potential for jaggies !

Any advice or views welcome on this....

Hi,
You should first resize and apply sharpening as your last task.
I use a mask to hide and reveal sharpening. With the mask you can even set the level of transparency on different areas of the image. e.g. you coud easily apply only 50% sharpening on the titles to avoid jagged lines.
I like 1024 px wide images but on larger screens larger resolution looks much better as it fills the whole screen. 1600 is excellent if you have the quality but most of the people don't have that size of monitors. When I'm bwowsing through the DB on my wife's laptop I usually don't even open 1600 wide images.
Regards,
G.

Hi G - sound advice and agree. Perhaps I did not make myself clear. The jaggies appear at the time of resize before any selective sharpening process begins !! The reason I might try again with a 1600px submission is that reduces the impact of jaggies compared to a crop around 1024...

I see what you mean. If your RAW is good enough to stand a higher resolution resize I'd give it a try.
Another thing I usually do frequently is to check the DB for similar shots and see what others have.
Here is one like yours:

This is a bit higher resolution, but I'd say not much better on the subject jaggies.

Good luck!
