I use this blending mode to add a bit of extra pop to photos that are otherwise not bad! It's an all-over boost that really takes your photos from so-so to FABULOUS!! I did a tutorial HERE that explains how to use a soft-light layer to give your photo that pop!

You are very welcome - hope you use it often. I sure do! Sweet, simple, basic, done!
