What is Frequency Separation?
And why am I doing a tutorial in which I apparently do absolutely nothing to the photo? That's because this is a very useful and popular technique in professional retouching, that people on youtube generally spend hours trying to teach. There's a video out there called 'super fast frequency separation technique' that lasts twelve minutes. I've managed to do it in one minute twenty, which I think could be quite useful. It's aimed at people who already know what the technique is for and just want to know how to do it correctly, and it might come across as a bit mystifying if you don't know why you'd want to do this to an image. Basically by splitting the high and low frequency parts of an image it's possible to do a much better job of retouching - especially for skin in headshots. I'm planning to do some more followup tutorials to make use of the split frequency layers to show how useful they are, but I wanted to keep this short and to the point.
The image I'm working on is a headshot I took for my mum a few weeks ago and I'm using it with her generous permission. Once I actually make any changes to it I will post a high resolution version of the image alongside the tutorials.
This is my first time recording a video tutorial, and it's been quite an interesting learning process to get all the software and hardware to cooperate to get something that looks reasonably good. I ended up having to sit on the floor to make everything possible. I've never got into after effects much before, so the opening title was the hardest part. I recorded the guitar part and did the sound editing in audition. The screen cap is done with Camtasia Studio 8, which also generates the keyboard overlays. Most of the job is done in premiere though.
