Multiple Imagery Technique

What is Multiple Imagery?
Multiple Imagery appears in grid form, usually made by 3x3 or 4x4, and is shot of one subject at various angles.

How do I do it?

1. Pick a subject to shoot 
2. Take either 9 or 12 pictures of that subject from various angles 
3. Edit each picture individually, make sure the size of each image is 5.5 width with a resolution of 300, then flatten each image 
4. Open a new transparent document and rotate the page so it is landscape
5. Drag each image onto the blank document, joining each picture or leaving gaps and then put them in the order which you desire
6. Crop the left over blank sides and then flatten the image if you wish to have it as a jpeg, if not, do not flatten 
7. Lastly change the size of the overall image to 17 width with a resolution of 300
