Can anyone share how to do this lighting effect in Photoshop as a post-process?
- Blur image
- Color filter the whole image yellow hue
- Add opaque paintbrush layers (with huge brush) for blue and purple colors
Besides the obvious Lens Blur it looks like it was overlayed with a Gradient Fill layer using a custom color gradient, or the overlay could have been a layer containing a few coarse color splotches: yellowish on bottom, bluish left, and purplish right.
This image may actually feature very little Photoshop or post-processing from any computer software at all. It may simply be taken with lights gelled to the appropriate color, and with the lens defocused.
