GIMP Tutorial - Swap a face

Given the amount of photo editing going on with the Raytractors lately, I thought it would be a good idea to do a GIMP tutorial to show how to do some fun photo editing.

So first, we need a base image and a victi... volunteer to swap faces.



Yes, yes, these two will do nicely.

Step 1 - Scale the images. The strawman image is way too big compared to Ray's face. We need to scale it down. Go to Image -> Scale Image.



Step 2 - Make a new layer for the strawman image. Set the background to a solid color. We are going to be "poking holes" through the strawman image. Go to Layer -> New Layer. Copy and past the background. Use the fill tool on the background to set it to a solid color.



Step 3 - Create a mask for the strawman image. A mask is like a transparancy channel where white is opaque and black is transparent. We're going to make a fully opaque mask. Right click on the layer to add a mask.



Step 4 - Take a paintbrush and start drawing black over the mask layer. It will reveal the background. Use a brush with a "fuzzy" edge. It will help the edges blend better with the background.



Step 5 - Zoom in with and use a smaller brush where you have to.



Step 6 - Crease a new layer (Layer -> New Layer) above the background and below the strawman image. Copy and paste the image of our vict... err... volunteer.



Step 7 - Use the layer zoom and rotation tools to fit the image of the volunteer onto the body of the strawman.



Step 8 - Edit the mask layer as needed to fix any spots that need a little more transparency.



Step 9 - Use the Effects -> Light & Shadow -> Drop Shadow filter on the strawman image to have it cast a shadow on Ray's face. Use the Effects -> Light & Shadow -> Lighting Effects on the victi... volunteer's face to help match the lighting with the original image. Adjust the contract and brightness on the volunteer's face to help it blend in with the strawman image (Colors -> Brightness Contrast).


(Note: The image above only has the drop shadow added.)

And... We're done!

  2. The tutorial isn't as precise as I would have liked since print-screen didn't let me take a screenshot of the menus.

    Let me know if you run into any troubles.

  3. But if you already understand the concept of layers and transparency, you should be fine.

  4. Thank you, maybe I'll come back to that. I've already worked with photoshop, but you mentioned some things, I haven't heard before.

  6. Thanks Kaitlyn!

    I hope to get a chance to try that out sometime. I have some other photos I'd like to work with also.

    I hope you're doing well and I like your blog. I hope you'll have time to explore some other areas.

  7. Jinx,
    I find it facinating and very pathetic that you can not seem to see anyone have a good laugh.

    You have obviously never studied sociology or psychology so you would not understand that is good for people to let out there inner child from time to time.

    letting your shorts get all knotted up into your asshole every time someone has some fun must be quite stressful.

    You are a humorless pathetic boob. That seems to be a common trait in fundies, never smile or allow anybody to have some fun.

    I'll bet you are the life of the party- not.

    I'm sorry you didn't enjoy my tutorial. It was supposed to be fun and relevant.

    If you don't mind my asking, what exactly was so immature about it? It's a pretty standard comical photo edit.

  10. I haven't worked with GIMP much, but I have used it more than enough to realize that this is a very nice tutorial. You put a lot of effort into this, Thanks Kaitlyn.

    BTW, what OS are you using? Its linux of some form, but I'm only familiar with Ubuntu... and this doesn't look much like it... yet its still vaguely familiar.

  11. It actually is Ubuntu with a standard Gnome desktop.

    I use the "Glow Cinder" GTK theme with "Shiki Colors Brave" emerald skin.

    I'm using the Dropline Neu! icons.
