A Tip on Photomanipulations!
You may know me for my many photomanipulations, and a big help in making those is to have a Bitz Box.
What’s a Bitz Box? It’s a term taken from miniature building for the box of extra bits that come with a model, for use in later projects. The Bitz Box in photomanipulation then, is the digital equivalent of that.
Specifically it’s a folder of assorted transparent images of items that either I've personally taken pictures of; public domain images that I got from Wikimedia or stuff from Pixabay. And, while previously such a thing had been slow going due to how much of a pain it was to extract the transparent images, significant help in that's been Remove.bg
It's a site that uses neural networks to remove backgrounds from non-transparent I basically plunk the pics in, and it removes the background. Tho, then the problem is that it just produces it as a relatively tiny preview. But I do have a solution to that!
In that, I just copy the preview, paste it in a layer over the original in my art program of choice (I use GIMP for the record), enlarge the preview to the size of the original, color-select the transparent parts of the preview, go to the original layer, delete it, and voila! A nice, quick, clean way to make a pic transparent!
Tho, sometimes you will have to manually alter the selection to encompass parts remove.bg left out, or erase stuff after the fact that remove.bg didn't take out, because that algorithm can miss stuff. Heck, you may have to alter the picture before putting it in Remove.bg for the sake of it actually doing the job of making the parts you want transparent.
But even then it's super useful, and a great way to build up a Bitz Box! Hope that helps!
