Any advice on how I can get rid of some the of artifacts caused by shooting through glass? They are easier to see on the bigger version here (external link)

Normal healing does not seem to work to well with this kind of thing, any other approaches I can use?

Of course any other feedback on the photo appreciated also, best of a lot of shots of him, the only one when he actually looked in my direction.

Did you try it with a polarizing filter to cut back on some of the glare? Also, you can get flexible lens hoods. Also, try to get as close to the glass as you can. It will tend to throw defects out of focus.

No polarizer, never in stock when i go looking for one, and probably not worth putting it on the kit lens (only zoom i have) as the front element rotates a lot as it looks for focus and a little as it zooms either side of 35mm.

I have been trying for a while to learn how to get rid of those artifacts but been unable to. I haven't found anyone who can do it without a lot of work and basically rebuilding the photograph layer by layer and a lot of trickery which makes the picture not very like the original.

Unless you're being paid well for it, erasing glass reflection artifacts simply isn't worth the time. A polarizer is the only reasonable option, which is one of the extremely few filters you can't duplicate in photoshop. You really have to re-build the entire frame a few pixels at a time to get rid of it.

Tiger and center is much better, still needs a bit of work at the top left and top right.

The refection basically adds a bit of blue and makes that part of the image a bit more blurry, so if you neatly select small areas lightly sharpen, adjust the levels a bit to darken, you will get most of it. Also you can do a manual dodge and burn by making another layer, but instead of just using black and white, use and airbrush with an ink that matches the area you are working on, and make that layer a grain merge so that it enhances the texture of the object below, you can make its opacity about 20%.

I think at its current stage only pixel peepers would be bothered, that's good enough for me, but I'll see if i can bring it any further.

Sorry if I'm being a jerk here, but it still looks like it's at a zoo shot through glass.

That's a perfectly valid opinion, because........ it is a zoo shot through glass :lol:

Its good enough now IMHO that most non-photographers could look at it and just appreciate the tiger for what it is.

That's true. People who aren't looking for nit picks usually don't find them so easily. Also worth mentioning about the polarizer; you do lose about 3 stops of light, so sometimes the trade off still isn't worth it.
