Cells are the many pictures that make up the source picture. When creating a Picture Mosaic, each cell is analyzed and is optimally placed into the source as to closely map colors and shapes of the source. For examples, please visit our mosaic example gallery.
The only cell requirement is that all cell pictures that you submit (whether they are digital or non-digital) should be of similar orientation. In other words, you should choose pictures that match the cell shape you have selected for your Picture Mosaic.
For example, if you select a horizontal rectangular cell shape, all of your pictures should be of a horizontal orientation. See the below illustrations for further clarity.
Note 1: Cell shape is independent of the final orientation of your mosaic. For example, your source may be vertically orientated, while your cells are horizontally orientated (or vise-versa).
Note 2: Digital cells may be in jpg, tiff, or bmp formats; a minimum of 80 pictures is required, there is no maximum (as the more pictures you can provide the better). Your images should be at least 640x480 pixels or at least 100 dpi, however these are minimum requirements, so higher resolutions are recommended. Both color and grayscale images are acceptable. Image size (or resolution) can vary from image to image, only orientation is important.
Note 3: Non-digital pictures must be at least 3'' x 3'' and no larger than 8.5'' x 11''. Both color and black and white images are acceptable.
What if my cells are not all of the same orientation?
Q: What may happen if I do not follow the cell guidelines?
A: For both digital and non-digital cells, it is likely that you will have some improperly cropped cells as shown below.
Q: How are cells cropped that are not sorted or that do not follow the cell guidelines?
A: Cells that do not match your selected cell shape will be centrally cropped regardless of content within the image.
The above problems can be avoided by following the cell guidelines.
