Meostigmat_f1.7_100mm
This LoRa is intended to modify bokeh effect on the lights in background.
It should slightly increase the size and blurriness of the lights which are out of focus (frontal and background bokeh effect). Also, it converts the circle shape of bokeh lights into a lemon or cat eye shape. Additionally, it adds the areola or light shards protruding from bokeh lights (simulates the imperfections of vintage lens).
Use higher CFG values to make it following better to your prompt. LoRa trained with relatively small dataset. It can affect the scenery (attracting it toward snowy street with heavy weather effect or toward a flowers macro scene with strong separation). Also, it can affect the faces at higher weights. I tested it up to weight of 1.35.
PS: Meostigmat - is a relatively rare lens with lovely render of out of focus parts of photograph.
Description
Meostigmat f/1.7 100mm - relatively rare fast lens with creamy cat eye bokeh effect and spherical aberrations of out of focus parts of scenery.

I apologize if I'm not getting it, but why does this training seem to introduce xenomorph elements?
it is no training. Xenomorph added by promt. I am just an H.R. Giger's fan.
This LoRa showed itself to actually reducing the Xenomorph effect and it shifts the heads to be more realistic human head. Look closely to the comparison grids. Left side with high weight and Right side with almost zero weight.
Hey @homoludens , I tried out this LoRA with a few different prompts and it does enhance the background blur/bokeh or add it if not present. Generally I saw warmer tones with the LoRA than without, and quite a shift for human faces to photoreal. Some of the blurring effect got added to faces. Overall I can see how it would be a useful model for doing straight photorealism. The stuff I’ve been doing lately tends to be unreal/surreal, so the Meostigmat_f1.7_100mm LoRA doesn’t help me. It’s an interesting idea all the same - I’m keeping the LoRA on disk in case I need to do a warm-up/bokeh fix on photos in the future. For what it’s worth, I’ve added a gallery below to show some With/Without comparisons using CineroXLV15Yummy.
If I've got some hidden point correctly, it would be much better if this LoRa can amplify the bokeh effect WITHOUT SHIFTING TO PHOTOREALISM?
Am I correct?
Also, I feel that effect on the face needs to be minimized. I should buy this lens and take much more shots without humans in order to reduces the influence of the faces.
PS: Thanks for comment!
@homoludens Yup - bokeh is nice, colour shift OK, but the photorealism is meh. I use a 60mm macro for classic flowers (and sometimes ppl) with big bokeh - it works well, perhaps sometimes too much too cliche. A LoRA that could convert generated images to the same look would be amazing. I should really find the time (ha ha) to try it myself... too many other projects on the go, but have added this to my to-do.
If you experiment with new version of your LoRA I'd be happy to test :-)
@chromesun noted thx
