When you open an image from 3DS Max into Photoshop, does the quality of image get degraded?

I have a rendered image from 3DS Max but I need to use Photoshop to add some text to the image. I am wondering if I use Photoshop to add text to the image, will the image become bad quality? Or is there a way to use Photoshop in order to maintain best quality?

Once I add the text to the image in Photoshop, I do a "Save As" and select Jpeg. Under the JPEG Options, I select the Quality options to "Maximum" which is "10".

Thanks for any advice!

What type of image are you rendering out of 3ds? You should have no issues if you render out at a higher bit depth.

For instance, my render output is always a multi-layer openEXR at a 32 bit depth. Then I take it into photoshop, do one layer of post production, knock it down to a 16 bit image, do another round of post production, then usually either just keep it at 16 and save out an 8 bit jpg if necessary.

The trick is (in my mind) is to make your post production changes at the higher bit depth so you have the color information to play with. 32/16 bit is flexible whilst 8bit isn't much.

I use a Jpeg file format if that is what you are asking.

That's your first problem. You shouldn't be rendering out jpegs unless you need to for some reason.

Think of a photographer. Any photographer that's not a silly goose shoots in RAW format, not jpeg. That's because RAW format contains so much more data than a jpeg image which allows for greater flexibility in post production. During processing they make the changes to the raw and then knock it down to a jpeg for distribution to their clients.

Are you using Vray or MR or something else?

Great information!

I am using Vray. I am making very large size poster 20" x 30" at 300dpi resolution.

So after 3DS Max render my image, what should I save the file as for printing large poster?

I'm making you a video example.

I think you would be better off rendering your image as a 32bit Tiff (just my suggestion.. I really like going 32 bit as it gives you the most options).

Have you had experience with different bit depth in PS before? I remember when I was first starting out this was something that took me a while to figure out.

No, I have no experience in bit depth in PS. Does it take a lot longer to render in 32bit Tiff? When I render the 6000 x 9000 Jpeg file, it took about 15 hours.

The print shop told me I need to send them a Jpeg file and it must be 300dpi resolution. So when I render in 3DS Max, I enter the Wdith: 6000 and Height: 9000.

20 x 300 = 6000
30 x 300 = 9000

Thanks for making a video for me to follow!

No. It shouldn't take longer (but the file output size will be larger).

Video below-

Notice that when manipulating the image via exposure the 32bit has more color information than the 8bit jpeg. What I did wrong was I did not collapse the exposure adjustment layer into the image layer so that's why you saw the jump in color when I converted to 16bit. You need to merge you layers into one before converting down.

Render in 32bit, tweak what you can tweak (exposure/gamma/levels), collapse adjustments, convert to 16bit, tweak image more (in 32bit you don't have all of photoshops tools available, 16 you do). Then from the 16 bit image you can save to a 8bit image (no need to convert to 8bit as from the 16bit you can save out a jpeg which are all 8bit by nature).

Jpeg is a format for compression. To get rid of all data that's not seen. It's a good handoff file type, but not a good file type to modify/work with.
