This increases the total number of pixels ○ (8x300x10x300) =7,200,000 pixels ■ 4x's more than before -Photos enlarged in photoshop in this setting results to an increased number of pixels (which causes pixilation) When combining images in photoshop it must: correct answers They must be at the same resolution ■ If not, the file that is being transferred will assume the resolution of the destination file ■ They must have the same colour model ■ If not, the final file can become corrupted!
