Processing Satellite Imagery in Adobe Photoshop (Adobe Photoshop Version: 23.2.1) This step-by-step guide will lead you through the procedure of: importing Landsat grayscale bands as 16 bit images; creating an RGB color composite from three of these bands; applying simple enhancements to your newly created RGB image; and then exporting your final enhanced image in a format that is easy to work with (8 bit .jpg or .tiff).

You can now save your image as a 16 bit per channel file (File / Save As) and choose .TIFF format.
When you downloaded your satellite images you will also have received a metadata file. This file will tell you the UTM coordinates for the upper left pixel of the image, the size of each pixel and the UTM Zone for the image. Simply open a normal text document (Notepad would work) and write the information as follows:
Pixel Rotation (this will be 0 unless you have rotated the image) Pixel Rotation (this will be 0 unless you have rotated the image) Ground length of each pixel in the Y axis (usually the same as the X length but it will be negative) UTM Easting coordinate for the top left pixel UTM Northing coordinate for the top left pixel
0 0 -30 443910 5521470 Once you have entered this information, save the document with the same name as the image but with a .tfw extension if you are using a .tiff image, or a .jpgw extension if you are using a .jpg image. This file must remain in the same folder as the image (move it with the image if you move the image) and it will only work if you have not resized, cropped or rotated the image. A GIS software package will ask for the UTM Zone information when you import the image (in this case it was Zone 10 North).
