How to do PS Render/Lighting Effect Manually?

Hi folks.

I have few situations where I would like to apply photoshop render/lighting effect, however, I would like to be in control, even though the dialogue box gives few options, I like to be able to do this by hand through layer modes, masks and such.

I had a go at it using "soft light" layer mode but was not happy with the results, I think it is sort of close but not close enough. Any ideas. Thanks

Render all your lighting effects on a new BLACK layer set to SCREEN. That's all there is to it.

Doing it in soft light will not work, as the light that you will introduce will contain pixels with value lower than 50% gray, and that will darken the photo as soft light is a contrast mode.

When you say "render lighting effect" I would assume white soft brush set to low opacity. I will give it a shot. Thanks

No, i really meant using the lighting and lens flare effects under the filters menu. You can also do it by hand with a big blob of white using a soft brush, or a feathered selection.

Whatever you do to add MORE light, has to be done on a separate layer with any of the lighten modes (preferably a black layer set to screen), not the contrast modes.

I would like to avoid the filter all together if I can, I Was looking for ways to do it "by hand". I did try white soft brush, was sort of close but not the same results. Thanks anyway, was helpful though, at least I might be on the right track.

If you want realistic light into lens effects, that filter is the way to go. You might want to desaturate it though,, not realistic, but it looks better imho. Now, if you really want to do it by hand, it's better to fill a selection with white and blur it than just using a brush with limited size, although you can always resize the light blob.

Another option is to use custom brushes.

Nice. This is what I was looking for. 1 & 3 combined together should give me what I am looking for. Thank you ME_wwwing so much. I need to practice "thinking outside the box" for a while, this application for vanishing point is very interesting.
This opens up various possibilities, like swapping yellow for white for "sunny" effects, masking & inverting to control the BG, endless possibilities.
