I have 16-bit satellite GeoTIFFs from DigitalGlobe (QuickBird/WV2), which I wish to share with a colleague that does not have access to GIS software.
When loaded into ArcMap, these sattelite images display fine and have a natural colour scheme.
When loaded into Photoshop, these rasters appear black and need manual stretching/editing/colour-balancing of the RGB bands to be visible. My end result is a raster with the wrong colours.
How does one export these 16bit satellite images from Arcmap, maintaining the colour balance/stretch applied by Arcmap, so it is possible to view in Photoshop and other non-GIS image editing software with the same display as in Arcmap?
I have attempted two solutions (writing Arcmap's stretch to file by exporting the tiff and changing PS's settings to automatically stretch the tiff) with little luck..
1. Write the colour balance/stretch applied by Arcmap to file by exporting the tiffs, making the images visible in other software (Photoshop).
Unfortunately, when the tiffs are exported post-colour balancing and are loaded in PS they still appear black - meaning any colour balancing done in Arcmap does not display in the tiff file once exported to PS.
2. Replicate how ArcMap displays these rasters in Photoshop by changing photoshop's settings - so all images are automatically loaded into Photoshop with the same stretch / colour balance as in ArcMap.
I could only change the colour balance for each image, a tedious guesswork that led to images with the wrong hues of colour and contrast levels.
Note: I've tried GIMP, Ifranview, Photoshop etc and all image editing software displays these 16-bit GeoTIFFs as black. Only ArcMap automatically displays them in the correct colour balance. I need to give these images to someone without ArcGIS, so they need to be visible in PhotoShop, but I also need to retain the high-resolution of the original 16-bit TIFF format, so can't convert to another image format like JPEG.
