An attempt at using GIMP's selective sharpening tool. Would be grateful for any views/comments/tips/ideas/suggestions...see forum thread forum

V1 is the Before
V2 After

The area selectively sharpened is from the eye to the nose

This method has worked well, and theres clearly an improvement in sharpening in the eye area in V2.

The concept of layers and flattening layers is common to most image editors. What it means is that youe adjustment is done on a copy of the original, - a second "layer", and when your finished, if youre happy with the results, you have to "flatten" the two layers back into a single copy or layer, making your adjustment permanent.

Hello, Jeff. I looked at the image before reading what you had to say above, then went to V2 and thought, that's much better, selective sharpening used. Then I went to your forum link and understand what you have done. And I think you have done it well, it works beautifully. On your original, you have sharpness on the top of the iguana's back but not on the face, and this has made all the difference. In PaintshopPro I have a sharpening brush that can be adjusted in opacity/intensity and it allows me to selectively brush over areas that need sharpening without resorting to layers.
Just one other thing, which is more noticeable in the thumbnail, there is a branch or twig in your background which seems to protrude from the iguana's nose, so I think I would try to blur that a bit more. I would also clone out the white patch on the log at the bottom, but I am a bit of serial cloner.
I have done a modification where I used the dodge and burn brushes to blend in the stick on the right, then used gaussian blur on that area. I also cloned out the white bits.

thanks, Pamela

I had noticed the white mark but trying to clone out in picasa was a total failure (haven't tried that in Gimp yet!!)...hadn't noticed the twig to be honest but now I can see it...It's amazing when you look in detail at images what you can actually see

the mod looks great Smile

I had already printed the original image for my own use and was quite pleased with the result now I have something much better.

The focusing is something I need to work on...I decided to use auto whilst away 'cos I couldn't afford to miss out on those `important' shots (like this one). The only trouble is the D60 tends to find the spot nearest the camera and so you have to keep re-focusing until you get it hit the sweet then it can be too late

thanks for the feedback, much appreciated Smile

Hi Jeff,
I've just looked at your thread and I have to agree that using layers can be mighty confusing if you've never done it before. There's a dialogue box in Photoshop which keeps you abreast of what you are or have been doing with each layer.
It's been ages since I used GIMP so I'm not sure but I would have thought that there would be something similar. At the risk of asking a stupid question; have you by any chance got it hidden or turned off?
If it's any help, if you've ever used "Publisher" (not Word) you'll know how to work with "text boxes" and how you can lay one on top of the other with various adjustments. "Layers" in photographic editors work in much the same way.

Hope this helps.


Edit: Sorry! I forgot to say what a great job you've done with this. The tutorials are obviously working!

thanks, Jester

not sure whether they are switched off at the moment...having trouble remembering what I did afew hours ago!! Wink

never used `publisher'

I'm going to work my way through the tutorials and see if I can get a hold on how it works...may buy a book to back up the practical.

Interestingly I can now see ways of improving some of the shots that I thought weren't good enough (for me)...will load one tomorrow that I've managed to sharpen

thanks for the kind words..all encouragement valued Smile
