Merging rasters - some issues

[PrzemysławKłos]

Hi!

I'm not sure if it's right place to ask my question but I have an issue with merging rasters.

As you can see in the first picture, I have 4 independent layers with symbol 0 having no color.

Using "Mosaic to new Raster" is doing something like this:

Mosaic to new raster window:

   All I want to have is to just merge those rasters into one file and have symbology like in first case.

Any suggestions?

Export the image to a raster dataset. Change the stretch type in layer symbology, if required.

I keep "Copy raster" options default. How to improve the output?
