Could anyone explain how to cut a portion of a photo and place it on just a plain background (like white or black)? For example, how would I take a bird and place ot on a plain white background?
Thanks,
Nick |

Open a blank document with a white background. Open the image of the bird. Use whatever selection device works best for this bird to select it. Drag the selection to the white document. Presto!
That's the basics of it. You can copy/paste the selection instead of dragging. If you want to know HOW to make a selection, study some tutorials, there are so many ways to do it.

Once you have your selection use Edit/copy to capture it.
Create a new document and select the background to be white or black.
Use Edit/paste to put the selection in the new document. Use the move tool to place it where you want it.

It's so easy it's scary, isn't it? For your next lesson, do this:
Make the white canvas big enough for 2 birds. Select the bird int he original and set feather radius at 0. Drag and drop. Then on the original reset feather radius to, say, 12 pixels, maybe even more depending on how big the bird is. Drag and drop that. Look at the difference, especially when you magnify it somewhat. Working with the feathering makes all the difference in the world in how natural the superimposition will look.

A more flexible method of doing this is the following:
> double-click your bird layer (this turns it from 'background' to an active layer
> add a new layer and hit [cmnd]+[backspace] to add the white background (assuming your colour swatches are black + white)
> drag the white layer beneath your bird layer
> select your bird layer and go to menu > 'Layer - add layer mask - reveal all'
> click on the new white block (the mask) to the right of your bird image
> airbrush the mask with black and watch the areas of your image you don't want disappear
You can do the opposite by selecting menu > 'Layer - add layer mask - hide all' and airbrushing with white - which will gradually reveal your image instead. The advantage of working this way is that you never lose any image data, but simply hide it. You can then edit it with ease should you want to fine tune the selection of the bird's edges, allowing a seamless blend.
This method is great if you want to blur a background and leave an area sharp - in which case you would dupe the bird layer, blur the bottom one and mask the 'sharp' one.
Hope that makes sense. Very often the simplest techniques take a while to explain but take only seconds to experiment with! As long as you you ensure to save a copy and not replace an original, what have you got to lose by experimenting? |

There is an easier way to do it.
Make sure your background color is white.
Crop out the the part of the photo that you want to place on white background.
Crop again. But this time make the crop larger then the image. Drag the nodes out of the image edge. shift+alt if you want to have your image exactly in the center.
Hit return.
Your image with white background is ready.
