can you 'merge' add images?

Toobis

Worth a shot at asking; is it possible to 'merge' render images together after they are done? say I had a standard render of some guy in some location just standing there and I wanted to merge add another render of the exact same image only done with modifications of someone standing behind the person. As the images are exactly the same apart from the new person in the frame they won't really look strange. Can it be done?

Maybe this might be something you have to do with outside software.

If your first image ('some guy') was rendered as a PNG, it should have a transparent background, assuming that you don't render the HDRI map.

If you load this and the second image into separate layers in Photoshop (or similar), you should be able to blend them together.

Yes, I do it all the time. You can use the canvas option, or you can render the background guy with the background, and render the foreground guy with a transparent background then take it into photoshop and put them together.

I do it in PS

The methods described by Tim N and Serene Night work in Paintshop Pro and the Gimp as well. I don't have Photoshop but I have both ot these, the Gimp is free. Most image editing software should be able to do this.

You can do it in DAZ Studio.

• Go to your Go to the Render Album Page, You will see up to the Last 30 Renders you've done. 
• Double Click on any one of them.
• This will bring up the Render Editor (This is also available from the Menu Bar > Render > Render Editor)
  • If you are combining two renders just drag and drop. 
  • If are are putting Joe Dude is October Fest, under the Preview window is an icon for open, go grab his photo. (
    • BTW, PNG's saved from the Windows Paint Program do not preserve the Transparency layer
• Render Editor allows you to Combine to RAW renders so they still have their Transparency ; adjust colors, Brightness and levels; apply filters like Blur, Soften, Sharpen and others; you can change the orientation; and of course Save out the results.

 

To Peter Wade's point:

There are quite a few alternatives to Photoshop (it is not the only game in town any more). They range from Free, donation, and under a hundred Dollars.

If you are on windows there is Paint.Net is donation-ware, Gimp is the same.

There are several on the MAC, Gimp for one.

For relatively low cost for either the Mac or Windows, there is Affinity Photo. Neat thing about it, you can use all the Photoshop Brushes, you can find here.

They also have a Illustrator Replacement called Affinity Design.

Hey @Serene Night, do you know of a youtube video tutorial on the Iray canvas option? Do you just use the default Beauty canvas and hopefully that will create separate layers? I'm doing CPU-only renders b/c I don't have an Nvidia card, so it would take a long time to create separate background/foreground renders.
