Joshua in the UK asks:
I shoot for flash-ambient blending and find that when using the darken-mode window pull technique I get shadows cast on balconies when I flash my windows. Is there a workaround for this?
Yes; with this technique, where you aim the flash(s) directly into the windows your flash(s) can cause unwanted shadows. The workaround is to just remove the shadow in Photoshop or move your flashes around to reduce or eliminate shadows.
One way to control shadows from your flash is to use a single flash and shoot a separate flash frame for each window as Nathan does in this window pull tutorial.
Does anyone have any other advice for Joshua?
