Training Dreambooth with old poor quality images (old 35mm photos)

[SorenTruelsen]

Hi Guys
I have scanned a shit load of old 35mm negatives from my youth. When compared to pictures taken today they are.. well .. out of focus, grainy and low resolution. But ... I have A LOT of them. Like from just a summer vacation I have around 100 with myself on them.

I have tried normal DB settings, but the model was not really that good, always something wrong with eyes and facial features. I then spend quite some time trying to enhance/upscale them via different sites, it helped a bit, but still .. not too happy with the result.

Any suggestions to settings in Dreambooth, or would a Hyper Network be better ... basically, any suggestions on how to approach this?

thanks

use 10-15 pictures that share the same style, use the V2-512, start with 1e-5 and 800 steps unet, and 1e-6 350 steps text encoder, test the model, if not enough, resume only the unet for an additional 200 steps at 8e-6 then test again, keep adding the same amount until you get the right result.

Ill try - thanks

This did not really give the hoped result. I am now trying with a large amount of pictures (57) and 12000 training steps at 1e-5 to at least try to get it overtrained

what is you goal? Do you want more of the old 35mm style photos or clear and modern pictures? Or do you want to re-create a younger yourself as a model?

Use the model you made first and generate 100 pictures, but add "modern, Sony RX100, shoot with a Iphone 10"....to the prompt. Also add "out of focus, grainy,low resolution" to the negativ prompt.

After that you take the 15 best pictures and make a new dreambooth run with Bens settings above.

Furthermore, you can use Automatc1111 to enhance the faces first, using the Extras Tab and Codeformer set to 1
