Technical Midjourney Question
June 1, 2023 10:58 AM   Subscribe

I feel like I'm climbing Mount Everest when maneuvering Midjourney, the generative artificial intelligence program. Are there any mavens here in the MF hive?

My main question is fairly simple. I found an image someone created in Midjourney and posted it to a FB page I follow. I've tried asking the OP about the prompts that created the image, but they found it somewhere on Tumblr and had no clue.

Is it possible to upload an existing Midjourney-created image and have the program duplicate it at a higher resolution? My FB image is way too small to use in InDesign.

As far as I know, you can't just ask it to upscale an existing image, but a few ideas (chime in if I am wrong on any of this, it's been several months since I've played with MJ)...
You could try uploading the image to MJ and use the /describe function to reverse-engineer the prompt, but even if it gives you something good to work with, you won't be able to replicate it exactly.
If you do a reverse image search via your favorite search engine and figure out who made the original, you can try to trace it back to their account. Unless they are on the Pro plan using stealth mode, the original is out there on MJ's site to be found.
If you have the original file name, this site explains how to find the original user.
But, long story short, it might be like trying to find a needle in a haystack.

I have Gigapixel. If you send me the image I can run it through. No guarantees on the results. Memail me.

There are lots of free image upscalers, here are the two that I use.

I've also found this youtube channel that has a lot of great info on designing effective prompts. It also helps to hang out in the public rooms- when you see an image you like, look at the prompt that generated it, then try using similar prompts and see what you get!

There's apparently something called "promptperfect" which will attempt to recreate the prompt from an image. It won't be perfect recreation, but it should be thematically close.

Response by poster: Thank you to everyone who responded. Some great suggestions here. I’ll report back after my attempts.

Something like this (Github) might be useful, too: You give it an image and it extracts the prompt used to create it. From that, you could reuse the prompt and generate a higher-resolution image. (I'm not experienced with Midjourney, so I don't know what it's capable of, but the software I use can generate images up to 960x960 as well as taller or wider non-square dimensions, and there's built-in upscaling.

Most midjourney images are public.

Normally, it'd be buried under all the results unless it's really really recent, but if it was shared on FB and tumblr, there's a better chance that its a highly rated image, so search through the galleries to see if you can find it:
https://www.midjourney.com/app/

Search based on what you think the text description would be. The pictures there show what the prompt text was.

And, take it back a step, *obviously* reverse image search it first, and see if you can find it on tumblr, asking the OP, or using search, or asking what group it might have been on, or even asking if anyone recognises the source.


If you can find the original on midjourney it's probably already been upscaled, you just click a link to make it bigger or create variations.
