adding reflections on glasses

i posted some time ago about removing sunglass reflections from lighting...and now i need help on the opposite --

basically i want to add the glare on the sunglasses's lenses -- i have tried using the paintbrush, creating shapes with the pen tool, and other freehanding techniques, but really haven't gotten it to where i want it.

any tips to get me in the right direction would be fantastic.

thanks!

sean

I would recommend finding a photograph of what would likely be reflected in the glasses and then tweaking that by up-ing the contrast and distorting it. You can then set it to a blend mode and mask it into the lens shape. If you tweak it enough the image won't read but the patches of light will be more organic than if you try to create them yourself.

here's an outtake image to give you a better idea...

this is the best i have been able to do:

by realistic, i mean not super realistic. just get a sense that there is a clear lens and have a distinctive highlight from the lighting somewhat.

this was pen tool > fill with white > quick mask > gradient > delete

I would recommend shooting the lighting source and tweaking it into the lens. You will have a lot of control over it and it will look more realistic than anything drawn. Here I have attached a very quick attempt combining a photo of a hallway which I have tweaked and set to screen at about 40% with a gradient to which I have applied a lens flare and tweaked set to screen at about 50%. The second image shows both the hallway and the gradient at 100% over a white background.

Something I didn't do which I would also recommend is blurring the area of the glasses where the thickness of the lens is housed, as glass would distort this area quite a bit.

sean,

one other note here; be sure to assess the original lighting if you're going to add shadows or glare or reflections. you're original reflection did not reflect an accurate lighting assessment. determine where the original lighting is/was and add your reflection accordingly. and pay attention to existing shadows; your original wiped part of the shadow of the frame. that may happen and be correct to do so, but just keep an eye on it to make sure it is.
