I got this photo rejected because it was over sharpened?

http://www.airliners.net/addphotos/r...ections/big/20061128_mirage2K1.jpg

Thing is, apart from adding a tiny bit of contrast, the only modification to the original is that it has been downsized. The original size is 3008X2000 and the format is JPG.

What to do?  Sad

Robert,

Very nice image! To be honest i've never experienced major jaggies when re-sizing and NOT applying sharpening but I have heard that perhaps re-sizing in stages might help reduce this.

Good luck with it

Regards
Colin

Sounds to me like you might have the in-camera sharpening set too high. Check the camera settings and make sure to have the in-camera sharpening turned off, or set to 0.

Cheers,
Sebastian

If you didn't sharpen the shot you could still, after resizing, use a softening mask to eliminate the jaggies.
Here's a quick edit, though since I'm not at my "post-processing computer" I'm not 100% sure about the result:

Down sizing an image will normally soften it just a touch. If your image has come out of the camera oversharp, as said above turn off your camera's sharpening process. One thing you can try in PS is when you re-size your image, set the Resample Image choice to Bicubic Smoother. This will not try and add any sharpening to the resizing process.

Good luck,

Jid

Robert,

What program and method did you use to downsize the image? I have seen this kind of "over-sharpening" look on pictures which was resized using a bad image editor or wrong method of resizing.

"The Gimp" is an excellent image editor. Both open source and free of charge.

Kind regards,
Jacob

Well, first you gotta create a duplicate layer which you'll then soften as much as required with the normal softening option (now the whole image is treated); you'll cover it with a mask layer (all softening disappears again) and then you take the brush tool and remove the mask (thus making the softening visible) where it is required.
After having treated all the required areas you merge the layers and you're done.
You can of course repeat the step as often as you want.
In addition the masking method works with about any tool, like sharpening, saturation, contrast, lighting, ...

That way you'll get the required changes only on those parts of the photo where you need them.  Smile

Hi Colin - get yourself onto e bay you can pick a copy of cs2 up for £10. Also Elements 5 is either just out or coming out and it may have Masks built in? I believe they have updated the file browser to Adobe Bridge too which is the browser in CS2 and is excellent.

I have PSE 5.0 and it does not have the capability to make masks. An individual would have to use the different versions of PhotoShop.

Hi Jacob,

I usually downsize the images in photoshop, and sometimes in MS paint.

No good idea!

That would explain the sharp edges on the photo, MS paint has a very bad resize feature.
