How to make a multiple image on Photoshop

Making a multiple image on photoshop can be achieved if these steps are followed:

• Open the images in photoshop
• If uploading the images online, be sure to adjust the image size found under the 'image' tab in the menu bar. Optimum dimensions for uploading should 600mm for the longest dimension (height/width) and the resolution should be 72dpi. This will allow for a good quality image without a large file size.
• We can then adjust the levels if we feel the image can do with some slight adjustments. We go into Image in the menu bar and select adjustments > levels.
• We then need to create Layers. There are various ways of doing this. The way I used was to use the selection tool to drag one photo on top of the other. With the magnetic lasso I would then select the image i'd like to remove from the top layer. Next, go to layer in the menu bar and select layer mask > reveal all. I would then select the mask in the layer window, then use the brush tool (making sure the swatch is on black over white) to reveal what was on the layer underneath. The other option is to cut and paste objects from one canvas to the next. When doing this we must make sure the image size and resolution is the same for both canvas' before cutting and pasting.
• There are also other steps we can take to help 'finish' the image off. We can use such tools like the burn tool to create shadows to make areas look part of the image and help match the lighting. We can use the blur tool to soften any harsh areas that make the images look separate. Also, we can clone stamp to match and go over other parts of the image.
• Once you are happy with your image you can then save the image. It should be saved as a JPEG so that when you are uploading, you can be sure the website you are using will accept this file format.

Now that you have followed these steps, you should be sure to have a successful multiple image.
