Usually, my cosplay photos are all edited by my lovely photographers (especially the dear @yenra!!), but I have taken photos just by myself or with a few friends sometimes, and I honestly wouldn't know where to begin with editing...
But now, I can at least get rid of my flyaways!
When I did my cosplay of Homura in her braids, the braids were a TOTAL mess in no time at all, which meant that knowing how to do something like this would have been so helpful. I mean, it definitely takes time, but if you have a few hairs that are driving you crazy, this is how you can fix it!
If people like this, I'll try to find more basic editing videos, but I think this one can be really helpful for a lot of cosplayers so I'm just sharing it first :)
