Create a collage in Gimp

template collage in gimp opener Create a collage in Gimp

One task I perform regularly in Photoshop and Lightroom is to assemble multiple images on a single page for printing.  I love displaying my photos, for example, as triptychs –which are three side by side images.

I’ve posted before on the process in Lightroom here (http://projectwoman.com/2009/07/creating-a-triptych-in-lightroom.html) and here (http://projectwoman.com/2009/10/how-to-select-and-compose-a-triptych-in-lightroom.html)and today I’ll show you how to do this in Gimp using a set of templates I have created for you and that you can download free.

These templates work with both Gimp and Photoshop and you can find them here: http://projectwoman.com/articles/45PhotoshopTemplates.html

Unzip the files and open the one to use in Gimp along with the images that you want to use. I’m using the Triptych.psd file.

Start by viewing the template you are using and, in the Layers palette select and discard the top three layers which include the instructions for using the template in Gimp and in Photoshop and Photoshop Elements.

Select the first of your images, choose Select > All  and then select > Edit > Copy to copy the image to the clipboard.

In the template click on the layer marked A and choose Edit > Paste as > New Layer. This pastes the image from the clipboard into the layer immediately above layer A.

Click the Move tool (set it to Layer) and drag the image over the top of the shape on the right. If desired, click the Scale tool and scale the image to size it larger than the black rectangle.

Move the portion of the image that you’re most interested in seeing over the shape.

Now, to crop the image to size, click layer A, right click and choose Alpha to Selection.

Now select the Clipboard layer that you’ve been working on, choose Select > Invert and press Delete.

The image will be clipped to size using the template shape as a guide to the size. Choose Select > None before continuing.

Repeat this process for layers B and C – select and copy the image to use, click the layer you’re working with (B or C) and choose Edit > Paste As > New Layer.

Move the image into position and scale it if desired. When scaling, making sure to lock the width and height so that the image is scaled in proportion.

Right click the layer you’re working with – Layer B (or C) and choose Alpha To Selection. Click your newest clipboard layer and choose Select > Invert and then Delete.

When you are done you should have all 3 images in position.

This image has a background layer behind the pictures which currently shows white. If you prefer to add a solid color behind everything, delete this layer and add a new layer filled with your choice of color. Here I’ve added a new dark grey filled layer.

You can finish off the design with some text or simply save the resulting image.

These storyboard templates are a good place to start with your picture layouts. You can find similar templates elsewhere on the web so start with a search for “Free Photoshop Clipping Mask Templates” or “Free Storyboard templates”

Photoshop Creative: A Simple Composite

 composite final e1291598025313 Photoshop Creative: A Simple Composite

In this post, I’ll show you how to create a simple composite by placing one image in another. Along the way, I’ll not only bend one image to fit its new position but I’ll also show you a layer style trick that overcomes the problem that you’ll see if you scroll down to step 6 and take a look at what happens when I mask the image to make the fingertip show.

composite step1 e1291597991149 Photoshop Creative: A Simple Composite

1 To create this composite, open the images to use. We’ll assemble the composite in the image of the plaster hand. Start by dragging the background layer from the photograph into the hand image. It will appear on its own layer and you can now close that image as it is no longer needed.

composite step2 e1291598058691 Photoshop Creative: A Simple Composite

2 Size the imported image to fit where it needs to go. In this case the border will be added inside the image so I’ll make the image almost as large as the cardboard it will be ‘attached’ to.

Size the image in proportion so you don’t skew it. To get it to fit on in dimension it will probably be either too tall or too wide in the other dimension and that’s fine.

composite step3 e1291598446889 Photoshop Creative: A Simple Composite

3 Once you’ve applied the transformation, select the rectangular marquee tool and drag over the area of the photo that you want to retain. Choose Select > Inverse to invert the section and press Delete to delete the excess image.

composite step4 e1291598119202 Photoshop Creative: A Simple Composite

4 To warp the image to fit the shape of the card, select the image and choose Edit > Transform > Warp. This adds a series of warp handles to the image. Drag on these to bend the image so it fits over the area you want to cover.

When you’re done, confirm the transformation.

composite step5 e1291598164468 Photoshop Creative: A Simple Composite

5 To add a white border around the image as if it were a photo stuck to the card, select the image layer, click the Add a Layer Style button at the foot of the Layers palette and choose Stroke.

Set the color to white and the size to a size appropriate for your image. Set the position to Inside so you get square corners on the image (if you choose Center or Outside the corners will be rounded).

 When you are done, click Ok.

composite step6 e1291598200397 Photoshop Creative: A Simple Composite

6 With this image layer still selected, click the Add Layer Mask icon at the foot of the Layers palette.

Select a medium hard brush, set the foreground color to black and paint on the mask to reveal the finger on the underlying layer. This makes the finger look like it is above the image and not behind it.

One simple way to do this is to hide the photo layer and use a tool like the Quick Selection tool to select over the finger on the background layer. Then, with the selection in place, display the top layer and select its mask. With black as the foreground color, press Alt + Backspace (Option + Delete on the Mac), to fill the selected area on the mask with black.

You’ll see that we have some problems with the mask because it distorts the stroke around the picture. We want the stroke applied to the image and we don’t want the mask to have any effect on it – right now it is having an unwanted effect.

composite step7 Photoshop Creative: A Simple Composite

7 To solve the problem, double click the Effects entry in the Layers palette to open the Layer Styles dialog. In the Blending Options area of the dialog, select the check box for Layer Mask Hides Effects.

This configures the mask on the layer to hide not only the image content on that layer but also a style applied to that layer.

Thank you Kevin Ames

fantasy1 Thank you Kevin Ames

I have just returned from Photoshop World in Orlando and I am full of inspiration for upcoming projects. However one of the classes just inspired me so much that I had to start playing with the concept first. The idea is from Kevin Ames who taught it as a class called Fantastic Portraits…It’s Smoke, Mirrors & Photoshop.

The starting point is half a face, mirrored and stuck back together and then it’s up to you. This is my finished project – it’s a tiny file as I did it on the plane home and I really wanted to conserve battery but still get a reasonable result. With smaller images in Photoshop, of course everything goes much faster but the downside is that the final image is less useful because it is very small.

Here in addition to mirroring the face, I replaced the lips, pupils and part of the nose to get the face I wanted. I used the liquify filter repeatedly to reshape the face and the dodge and burn tools to add highlights and shadows – my additon to the basic concept. Then I brushed on the dots, added lots of backround interest and fashioned her a gold necklet. It helps if you have lots of textures and other interesting elements to use – for example, her hat is a fancy street light from a local park and there is a metal grate, a stairwell and a rusty texture making up the background.

It is a fun way to blow a few hours.

If you’re interested, here’s my starting image (courtesy of my friend Brenda), as you can see, the journey from start to end gave me something totally unrecognizable.

Cool Photo Apps #3 Create a life poster

lifeposter 733723 Cool Photo Apps #3 Create a life poster
Not all good applications come in big shinny boxes like Photoshop and Photoshop Elements. Many cool photo apps are available on the web and they’re free.

These apps do things that other programs don’t. They are fun to use and practical. In this Cool Photo Apps series I’ll show you some of these.

Popularized by the Mac and its iLife software, life posters are a collage of images arranged in a grid layout. Life posters look best when you use square images. On the PC you can create a life poster using the tools built into Picasa which you can download from http://picasa.google.com.

Here’s how to do it:

Step 1
Start with a new album by selecting File > New Album and give the album a name like Life Poster.

Step 2
Add the photos to the album that you want to use for the life poster. The order in which the images appear in the album are the order in which they will be arranged into your life poster so the first images appear across the top line of the poster and the next series of images will appear through the next row etc.. If you predetermine how big your grid will be, such as 4 x 4 images or 5 x 5 images you can determine which photos will be next to which other photos.

Step 3
When you create the poster, Picasa will automatically crop the images to a square format. If there are images that you would prefer to crop yourself, double click the image to open it and crop it to a square shape before beginning.

Step 4
To create your life poster, right click the album name and choose Select all pictures. Click the Collage button at the bottom of the tray area and choose Picture Grid from the Type list. From the location dropdown list choose a folder in which to save the finished collage image. Check the preview and, if you’re happy with the result, click Create to create the poster.

Step 5
You’ll find the image ready for printing in the folder you selected. Of course, having created your poster, you could convert it to a wall size poster ready for downloading and printing. Here’s a blog post that will show you how to do it: Cool Photo Apps #2 big huge photo prints
