Hi David,

I wonder if you have some comments, I noticed the histogram is automatically stretched when working with 16 bit imagery, is there a way to update? or can we default to 8bit?

Hi Elena,

Sure, I would be happy to help.

IIQ files are 16 bits by default, leading Correlator3D to stretch the histogram when displaying them. On disk, the colors remain the same, it's simply a different way to display it and optimize the histogram (which usually exaggerates defects).

Suggestions:
- Export a mosaic in .tiff format, important to note, when comparing colors use the same software to validate them.
- Generate the orthos in 8 bits using the corresponding option in our orthorectification dialog. This would avoid dealing with the stretched histogram effect, if not interested in a 16-bit product.
- Enter the mosaic editing tool, and un-toggle the "stretch" option. The button is located top-right in the main toolbar.

Keep me posted if this helped.

Thanks a lot! this is exactly what I needed.
