P: Transparent background or layers

Bonjour Adobe,

Je génère des images que j'importe dans Photoshop. Parfois, je demande de générer une image sur fond blanc. Je constate que le fond n'est jamais vraiment blanc.  Enfin, j'aimerais pouvoir générer des objets sur fond transparent. Est-ce possible ? 

Bien à vous, 

JSH.

To my knowledge there are only 2 ways currently to create an AI image with a transparent background (without the need to do any editing in Photoshop):

The 'Leonardo AI' website offers this feature. It is rather hit or miss, but does work to a degree.

On a decently powered PC install STABLE DIFFUSION + AUTOMATIC1111 (or better yet STABLE DIFFUSION WEBUI) + SD FORGE LAYERDIFFUSE

The 2nd option is the better option imo, but if you do not have a decently powered computer, running Stable Diffusion locally on your machine can be unbearably slow.

Hello @Mariano_Apaza8175,

Thank you for your message. I merged your message into this thread where others have raised this issue. Saving Firefly images with a transparent background is not a current feature. This thread is a request that Adobe add this feature to Firelfy.

Other replies in this thread offer work arounds.

Thanks,

Cuando intento descargar una imagen sin fondo en Adobe Firefly, aparece la primera imagen que puse para quitarle el fondo

No worries. You can use the same technique I included in that link for creating a consistent green background. You'd just be selecting all the white in the background instead of the green. It might not be necessary based on what you're getting but it's a great technque for removing any color from your backgrounds. Have fun!

Thanks mate. Your prompt "on a seamless white backdrop" works even better. Thank you and all the best from Copenhagen, Adam

Nice compositing work Adam. It's not obvious these are comps (at least, it doesn't "pull my attention" to anything that doesn't look natural (I like the little eyes in the woods). You might try using ("on a seamless greenscreen backdrop") in your prompt. The result looks like the attached and from there, use this technique https://youtu.be/DGeOLJKIHRE?si=k_8FwNg_QYOVr7WS to even out the various green values to make for an easy mask. Once you have a nice even green (even for hair, leaves, grass, trees etc.) that remove.bg filter does an excellent job separating the subject from the background. Might help. Good luck.

Here's another example. All the trees are rendered individually and manually isolated so they can be placed on the sceen with full freedom. Also the leaves that grow around the oak are rendered individually and then wrapped around the tree using the Transform/Warp feature in PS. So. it's possible with the white background to isolated complex images - but it takes a lot of time. But in the old days everything took time - it's ok. 🙂

Dear Cates,

Thank you for your kind response. The greatest challenges I've had is isolating rather complex images like the trees and the hut in the screenshots. The select background just won't cut it and I've had to use old fashioned techniques such as turning down saturation and playing with Levels to get a useful colour selection (black or white).  All trees and the hut are rendered individually and put together in Photoshop.

Let's hope the good people at Adobe one day implement the "render without background" feauture. 🙂

Thanks again and all the best from Copenhagen,

Adam

Adam, there are a number of workarounds to resolve your background challenges.

You mentioned a prompt you get fairly decent success with. If you use that prompt and then the generative fill/remove background (or select subject) you should get an excellent separation between character and background.

I've built a 3D cartoon character and background (two separate images) and then composited them together in PS. Attached are the steps used. Hope this helps.
