I have a project in ArcPro 2.1. I have the following layers (in draw order)
terrain multidirectional hillshade
I have opacity set to 5% on world imagery and 45% on protected areas.
Outputting the imagery (exporting the layout) is not producing the desired results. All outputs are set to 600 dpi.
View within ArcPro layout tab
Both the jpeg and pdf outputs are considerably lighter than the view in the layout tab. This seems to be due to the transparency of the World Imagery not being maintained. So I tried again outputting to png (32 bit alpha):
It seems like the transparency problem is persisting.
Finally the pdf seems to have the imagery tile boundaries showing. Is there anyway to prevent this happening?
This seems to be a problem with Pro. In order to accentuate the topography I altered the brightness and contrast of the multi-directional hillshade layer. It seems Pro is not respecting these changes and simply outputting the original image settings. Opening the same layer in ArcMap (10.4), changing the brightness and contrast and then exporting to pdf the settings were respected. Below is the original image in ArcMap and then the export of the altered brightness and contrast settings to pdf.

Now you may be wondering what the problem is here... I was. But watch what happens when you add a semi-transparent overlay in Pro:

Above you can see that introducing transparency trips Pro up and any image tweaking on the raster below is lost. I wonder if ArcMap has the same problem?

No... no it doesn't.
Which is a shame really as I like the way layouts work in Pro. But for this project... back to the map.
