Transforming a picture into a negative and converting a negative scan into a positive is deceptively simple, as I’ve shown in a short tutorial video:
Using a preset to do the job is of course even faster and, whether you start from a positive or from a negative, the process is identical.
You can of course easily create them yourself, but I’ve made the following two, if you prefer to just download them:
negative <> positive: used to convert from one to the other
negative <> positive (undo): to, ahem, undo the conversion if you have applied the first preset
If those are the first presets you get from me, the Kelmond.com preset folder will be created.
