Layer Sandwich

There's a lot I've forgotten from my high school photography class (a lot more than I remember, I'd wager...), but one thing I do remember is the unit we did on negative sandwiches. Since digital was still rather expensive, we worked exclusively with film photography (yes, I know that sentence made me sound like I am reminiscing about the good ol' days when dirt was invented). The idea is to load two negatives into the enlarger and simultaneously create an exposure of both images.

The task is harder than it sounds, though--some photos work better than others: the contrast, how busy the background is, location of the subject in each photo, and a range of other factors determine whether you end up with a really cool image, or just a blob of indistinguishable nonsense. I seem to recall wasting rather a lot of expensive photo paper working to create a decent negative sandwich.

Much as I enjoy developing my own film, one of the beautiful things about digital photography is that I can create hundreds of terrible negative sandwiches without paying through the nose for my experiments. So, using layers in GIMP, I decided to throw together a few negative sandwiches--or perhaps layer sandwiches is more appropriate for digital? I've spared you the worst of them, but I think a few came out pretty well. Below are a few of the creations, as well as the original layered images. Some of these I think came out well. Others I think are examples of poor attempts.

As always, feedback is appreciated. I'd love to get your thoughts!

Creating a Collage

As you know if you read my previous post, I've been invited to contribute a photo collage to a 2013 calendar focused on the subject of peace. Obviously this will be occupying most of my creative time for the next few weeks, especially since I've never used GIMP to create a photo collage. So, if you're wondering how it's done, here goes:

1. In GIMP, select File-->New to create a new file

2. Select Image-->Scale Image and set the dimensions for your collage. You can set the dimensions in pixels, inches, etc in the first drop down menu on the right (next to the boxes where you can enter the width/height. Note: the aspect ratio is locked by default. To change this so that it doesn't automatically adjust the width when you set the height (or vice versa), click on the box that looks like chain next to the boxes for entering the value for width and height. Click the "scale" button at the bottom when you are satisfied with the dimensions.

3. You're ready to add photos now! I'd recommend using photos that have already been adjusted for contrast, tone, etc as a starting point. So, how do you add photos? Well, you'll need to select File-->Open As Layers for each image you want to add.

4. If your photo isn't the size you want it to be (and most likely it's not), you'll need to adjust the size of the layer (NOT scale image, but scale layer). How? In the layers dockable dialog box. This is a little moveable toolbox that says "layers" at the top, and it should have one entry for each pictures you import, plus an entry for your background. The layers dialog box should open as a default in GIMP, but if it doesn't you can go to Windows-->Dockable Dialogs-->Layers.

5. In the layers dialog box, right click on the image you want to resize. From the menu that appears, select "scale layer". Now you can resize the image just as you normally would. You will need to do this for each photo that is not the right size.

6. Lastly, move everything around and fiddle with the background colors until you are happy with the appearance. That's it!


My photo collage is very much still a work in progress, but I figured I'd go ahead and share what I have so far. I'm still working on shooting/editing photos to add, and obviously I still have some work to do arranging the photos. I am the only photographer in the calendar, and since everyone else is painting or drawing, I've been using artistic filters to edit my photos to fit with the stylistic theme. I'd love some feedback if you have any initial reactions/suggestions :)
