Mosaic dataset image colours are different from original image.

Hello,

Can I please ask how to replicate colour settings for mosaic dataset so it is displayed as the original?

I have Image tiles that I load into mosaic dataset. Later I define and build overviews.

But when I compare Original Tile to the Mosaic DataSet I see that colours of Mosaic Dataset are different. Colours of Mosaic DataSet are a bit pale. See image below:

Does it have to do with the compression of overviews? But the colour is pale even though I zoom in to the scale of original image.

Any help appreciated.

Regards,

Ben

Hi,

I assume this is the same answer I gave a day ago to another question:

Have you properly set the MosaicDataset Property "SourceType"?
Your description indicates that your desktop tries to stretch the data. You can avoid that by setting the source type property from its (assumed) default of "Generic" to "Processed". This will let ArcGIS assume the data is like you want it to be and when adding to the TOC no Stretching will be applied.
