I don't know if this tutorial that I just finished is what you needed, as I might have gotten side tracked. But at the very least you are mentioned in it...
Hope it helps:

That's very generous of you! Extremely generous. Yes i have been looking at photos like that as well and kind of figuring out how i could use them. But i must be blinded by all the tutorials, since im not a PS expert either.
Photoshop i use photoshop CS5. I also have gimp i guess and inkscape!

Wow. Extremely helpful tutorial! Will definitely use this as reference to continue with the map. Thank you ever so much pixie!!
No problem
Keep sharing your stuff and improvements. By the way, since you want to make a railroad/transportation map - have you ever played Rail Road Tycoon 3? It has an inbuilt editor that allows to make cool in-game maps in 3D, and the best part is that you can start with a DEM file.
I have actually. But i dont have it anymore. The whole concept was to try and build an original concept world starting from an unconventional angle. Making a railroad map from it i think is beyond me and scrapped. Having that said, the map is still going to be finished but as a reference to the world obviously
You don't open DEM's in Photoshop, open in QGIS ( a free GIS software), open a raster layer DEM and make a Hillshade, then save as a jpeg or other file Photoshop uses. You may need to take a look at the QGIS manual tutorials to get a quick grasp of it. I'm sure others on this site are know more, but this is my basic understanding and use.
I followed the tutorial and the steps explain as such: "From this point on, you can start opening the heightmaps you just downloaded. Worrying only about the
general shape and direction of the mountains and/or of the slopes, copy bits and paste them on your file"
I needed wilbur and photoshop. Is it perhaps wilbur i have to open them in?
I have one question, I downloaded a bunch of DEM images but how do i open them up in photoshop cs5?.. File extensions i've got "BLW" and "HDR".
use qgis
but qgis will use GDAL a terminal text based program
basically for converting formats qgis is just a GUI got GDAL
http://www.qgistutorials.com/en/docs...bsq_files.html
a hdr is only the header for the image data ( a short text description of the data )
now DEMS are 16 bit signed data ( pixel values from -32767 to +32768 )
now saving it to a 8 bit jpg ( values 0,255 ) you will loose a LOT of data
also JPG is what is called a LOUSY !!! image format
the compression tosses information in the trash can and ADDS!!!! ARTIFICIAL !!!! ARTIFACTS !!! that are NOT in the original data
it is a VERY VERY VERY bad choice for height data
-- very bad choice
save it a a 32 bit tiff ( no compression !! ) image
photoshop can open that
