Compositing Images

Ok, So I am going to be combining this tutorial with photo of the week. The tutorial is over putting two images together and making them look like they are supposed to be together. The image I took for this project is of three girls with a pretty boring, if not bad background.

This image was shot in a RAW format and so after making the necessary adjustments I opened the image. You can either set the color balance before or after selecting your object within the picture. I chose to do it after I had selected my object because I feel it is better to work with individual objects rather than a entire scene. This is merely personal preference and is up to you. Try and match the color to the same white balance and other necessary settings to the image you will be placing your selected objects into later.


The next step is to get your polygonal lasso tool (L) and trace the outline of one of the girls. Once the girl is selected, go to Select, then Refine Edge. Choose a black background to go around your picture while you are working with the tightness of your cropping around your selection. You may have to contract or expand you selection a bit before you add a bit of radius and feather, then click Ok. Select inverse, then press delete to get rid of everything else in the picture.


Your window should look like this. At this stage go to Filter>Sharpen and Add Noise. Try only about 2% or less.
Save your file and place it into the photo your are transferring your selections to. Free transform the image till the size is right and repeat steps 1-3 with the other objects you will be placing in the photo. Remember to hold the Shift key while you are doing this so that you don't stretch you object. Once your objects are in, you may want to add a drop shadow or create a new layer, choose the Brush tool and lower the opacity. I think for this I lowered it to 13% and brushed my shadows in. I also slightly desaturated the girls to make their colors a bit more consistent with the photo. Look for highlights in the image that "pop" too much and darken them a little. In this photo I darkened top of the steps slightly. Keep playing with the different layers and blending modes to create the desire effect. Below is the finished product.

If you have any questions please feel free to ask!

ahem... for those of us who are graphically and design-ally challenged, what program are you using to edit these photos?

All these tutorials are for photoshop. I use version CS 3.

what is the RAW format?

JT said...

RAW format is what it sounds like. It is a raw image file. It contains minimally processed data from the image sensor of a digital camera. When you open the image in photoshop that is where you make the adjustments to the image finish the processing. You can change white balance, exposure, fill light, dark values, contrast, etc. This is currently the best format to shoot photos in because of how much you can edit them. Jpegs are processed in the camera when you take the picture which also limits the amount of editing you can do to a photo with out being "destructive" to it. Check out Betterphoto.com for some more tips on taking photos as well as photograpy jargon (aka slang).
