How much image degradation might there be when shooting through a typical, optically clear, window pane?
32.75% closed and 0% open [:P] Sorry no idea, what are you shooting at and why through a window.
I want to capture some bird photos. I'm using my porch as a "blind."
There will be some degradation - how much depends on the situation. There are many things you can do to minimize the impact of shooting through glass (or a screen):
- Reduce/eliminate light sources in the room (to reduce reflection)
- Make sure the window pane is clean (inside and out)
- Get as close to the glass as possible
- Use a wider aperture
- Use a longer focal length
Hope that helps...

In the recent 'post your images for the week' thread, my bison/buffalo shot was through the windshield of the car. On the RAW pane of DPP, I moved the left edge in, as the image was quite washed out. After that adjustment, it looks great. Perhaps not the sharpest ever at 100%, but still quite good. At the 50% view it looks as sharp as anything else I've ever shot.
If at all possible try not too shoot through regular glass, it is definitelly not that clear and will degrade sharpness and contrast significantly. But I'm also a perfectionist when it comes to IQand birds....[H]

If you have one as well, perhaps try a circular polarizing filter, given there's enough light.
