Some Advice On 'Bad Jagged'

Fri Dec 24, 2004 12:52 am

There is some serious efficiency going on in the queue at the moment. I have just sat down in front of the computer screen - no emails from any screeners yet, but I noted that I had one less in the queue. Via My Photos I was able to see that the following had just been rejected for 'bad category'. My own carelessness, as I had submitted this as an airliner, not cargo. So I swiftly resubmitted with the correct category.

Within I'd say 4 to 5 minutes my photos in the queue were down by one again. Same photo, this time rejected for 'bad jagged'. Still no emails. I don't know if the same screener viewed both images and found another fault, or whether it was looked at by someone new.

Either way I am surprised by this second rejection. I don't see any major flaws with jaggies in this one (other than minor stuff with the registration). Is that what you would say is the problem?

I won't cry about this not going in to the database, and I certainly don't want to be seen to be 'repeatedly' uploading a previously rejected shot. So, can it be improved and, if so, where, and in the end is it worth it?

Constructive views gratefully received.

Happy Christmas to all colleagues in the Forum.

The site seems to be having issues with emails at the moment, though I can't really comment as I haven't uploaded anything for a few months!

The only place jaggies are clear are on the horizontal stabiliser - looks out of place compared to the rest of the shot, so I'd assume thats the reason. Also to a lesser extent on the starboard (shaded  Laugh out loud) side of the leading edge.

Yep, leading edge of the horizontal stabilizer is what really bugs me. Also some on the cockpit windows and on the titling.

Nice shot.

Yep the leading edge of the horizontal stabiliser is probably the cause. Any easy way to fix shots like this assuming you are using Photoshop. Re-process it and go back to the sharpening process - I'm not sure how you are doing it, but assuming you are applying a standard USM. Say you are applying 200, 0.2, 0 - keep reapplying it until you see the horizontal stabliser start to go jaggy. Then hit the undo command to put it back unjagged. Save the image at its highest quality, and then close and reopen it.

This time go Layer --> Duplicate Layer. Keep resharpening until you are happy with the image as a whole. The stabiliser will go jagged. Then click the eraser button (below the clone stamp) and erase over the horizonal stabiliser - this will erase the sharpening only (not the whole photo!) since you made the duplicate layer. Voila! You have the image sharpened to your liking without the stabiliser going jagged.

This is a good method for images that need more sharpening but delicate parts won't take as much sharpening as the rest of the image needs and can take - for instance in between flaps, leading edges of wings and horizontal stabilisers and also cheatlines.

BTW - great shot!

Nice pic Paul!

Thanks Michael for sharing the Photoshop tip. I was just looking for something like that. Simple but elegant.

Another Photoshop sharpening trick then:

Duplicate a layer and sharpen it to just a bit too much. Set the layer blend mode to darken.

Duplicate this layer and now set the blend mode to lighten.

You now have split the sharpening in a dark and a light layer. You can use the Opacity sliders to decrease the amount of sharpening. This should give you improved sharpening results and more control!

For very delicate parts which are jagged too much just make a layer mask and paint on this mask with a black brush to erase the jagged parts. Nice thing of working with a layer mask is that you can undo it completely by painting the mask with white again and thus making the layer visible.


Kind regards,

Thanks very much everyone - I do appreciate your comments and suggestions.

Those couple of positive comments about the photo itself have spurred me on to try again, so it's back in the queue.

Happy Christmas.

All the best.
