Anyone know what causes glare like this from happening and/or any good post editing tips for removing it? It happens every now and then and always at the bottom of the photo. It was taken with a 2x telephoto conversion lense.
Thanks,
Jax

A bit of noise. Maybe try lowering the ISO setting on your camera.The lens could be bring more light into your camera. Focus in on something other then the reflective surfaces if on auto.
Anyone else with a better answer? |

| Try using a polarizer. You can experiment with polarized sunglasses if you don't want to buy a camera filter .... |

I'm going to guess and say that extraneous light from the chrome on the bottom of the motorcycle has entered the lense and has bounced around inside your camera causing the flare. From what I've read, many lenses nowadays are coated inside to prevent something like this from happening. If the teleconverter you're using does not have the coating, then it may be the culprit. Does the problem happen when you're not using the teleconverter?
If this is the cause, then a polarizer would reduce, but not entirely eliminate it. I would also try a different angle-of-view.

a lense hood also helps preventing the sun from contributing to glare (when it's not in the shot)

Thanks Olyuzi (and everyone else for your suggestions). Yes I'm thinking it's the teleconverter because it only happens when I have it on....not all the time though. I have a polarizer so I might have to use it everytime I put the conversion lense on. A bit of a hassle but oh well.

Anyone know of a good technique for reducing this type of glare in post editing software such as photoshop etc?

I've had similar problems. Try playing around with the lighting filters etc.
Anyone else know some good methods? |

| Thanks Hasp. Yeah I tried playing around with the lighting effects last night but I wasn't able to make it much better. A pitty because I have a few ok shots that are basically ruined because of this problem. |

(I can't figure out how to display a photo so try This )
This is what I quickly did with your image. I used the layers in Photoshop. I created a mask over the area that needed improvement. A method I like to use is to create a new layer, then use the gradient tool (fading to background) and create a gradient color over the area that has the glare (you may need to try this a few times to get the gradient to match your area of glare), and then select the gradient. Now turn the gradient layer off and select the layer with your image with the section still showing adjust the levels and try to make it match the rest of your image. When you are done you can always use the burn tools on a light setting to further improve the area. I sharpened it slightly as well. You probably will want to copy your image into a new layer before applying these changes so that you will always have an untouched layer image to go back to. It's a little hard to explain all of this in a short message but I hope it helps. There are many other ways that will work as well and the real key is to experiment a lot and see what happens.
