Ive recently started uploading to A.net and had a few get through with not many attempts. One of my main rejections is over-sharpening. The only thing is ive had ones rejected recently that were sharpened way less than ones that have been accepted and on some of the pictures i can not see how they look over sharpened at all. Is this just inconsistency in screeners? Also i know everyone is different but what settings do you roughly use when sharpening as not to over sharpen?.

Hi, is it possible for you to post a example photo that been rejected for over-sharpening? In Photoshop CS5 I often use both Smart Sharpen and Un-sharp mask. After I've done that, and if i found it quite over-sharp, I duplicate the layer and unselect the original layer. Then I start to rob out the letters and everything that looks over sharp. Then I just flatterna the layers and the picture looks better. Good luck!

Chriswade, I don't find that picture over-sharped at all. Maybe a little little on the engines and the a/c regestration. Try to do as I said in my earlier post. " I duplicate the layer and unselect the original layer. Then I start to rob out the letters and everything that looks over sharp. Then I just flatterna the layers and the picture looks better. "

Look at the edges where there is black (shadow) next to the sky - you will see jagged edges. This is evidence of oversharpening. I never sharpen the edges of shadows and am very careful about any place where there is high contrast.

You can fix this image by putting a lasso around these regions and then do a .3 Gaussian blur, followed by a 50,.3,0 unsharpen mask.

I agree this does look oversharpened. There is a white outline surrounding all the parts of the aircraft that are in shadow, and the titles on the fuselage and tail also look a bit oversharpened to me. What exactly did you do by way of sharpening? Do you shoot raw or jpeg? Do you have in-camera sharpening turned on by any chance?

Quoting chriswade (Reply 6):
then resizing

That may be where your problem is. Sharpening should be the last thing you do before saving the final photo. Don't sharpen before you resize.

Not necessarily. For your particular workflow that may be best, but perhaps not so for others. I do all of my sharpening before resizing, and I've had only one rejection related to sharpening in the past two years, so I must be doing something right.

I've experimented with sharpening and workflows and everything I've tried, sharpening before resizing has generally lead to jaggies or oversharp look to photos.

I suppose it's down to the individual to find what works for them.

Chris
I'm using Photoshop and I use the sharpening method suggested in the editing guide on this site - with three successive passes on separate layers of 50, 0.3, 0 and then rub out any areas which have ended up too sharp. I have a reasonable record on oversharp/soft rejections (helped by a few appeals recently!!) so it must be a fairly reliable method.
The other thing you need to be careful of is how much sharpening the camera itself is applying before you even start editing, even if you are starting from the RAW file. My Canon produces RAW files in a range of 'picture styles' which have different levels of sharpness and other adjustments already made, and it pays to either use a 'neutral' picture style or to reduce the amount of sharpening using the slider control in the RAW plug-in before you then start applying USM yourself. If you are editing from jpegs, then you don't have the options of doing this and it is easy to then end up with an oversharp photo even if you haven't applied much sharpening yourself.
Hope that helps.
John

That's what I was trying to say; there is no one best way to do things. It's a good idea to take all the advice you can gather, try different techniques, and end up using whatever works best for you.

This bit

Quoting JGreg (Reply 11):

is particularly important. There is no magic formula to apply the optimal amount of sharpening all at one go. You will end up either with some parts of the photo looking oversharpened or some parts looking soft. The answer is to sharpen selectively using layers.
