Upload & Sell: On
I still can't believe people actually STILL buy Lightroom presets. It takes 100s of hours to learn how to use photogshop...and it takes about 10 hours to learn how to use LR...
What's funny, there are many photographers even do blog posts on their purchase and tell clients what they use for editing. "Gee",says a bride, "I can't edit my own photos ,give me the raw files noooowwwww" hahaha
I use modified VSCO presets as a baseline for my work - it saves a lot of time, and it gets the effect I'm looking for.
As far as photogs posting it on their blog - one of the first things that popped up for my when I searched "VSCO 3" was the photog's review that I listed above. Given that a lot of us shoot for other photographers, that's pretty impactful marketting, not too mention a valuable interaction with VSCO that could potentially land you even more free publicity.
