Description

An SDXL 1.0 LoRa made by AI_Characters for producing photos with a better quality than base SDXL. Generally photographic images produced with this LoRa should exhibit better and more accurate to real-life lighting, better eyes (may need to be inpainted though) and skin, more and more realistic details, more coherency, very slightly better composition, more intense colors, etc...

While this LoRa was trained solely with high-quality post-processed photos as its dataset and will skew towards such results, with good and extensive prompting (see the example prompts below) one can also output much more realistic and true to real-life results than base SDXL can.

This LoRa is only a slight to moderate improvement upon the base SDXL output. Don't expect huge differences between this LoRa and base SDXL. But the improvements are there and noticable, especially the fewer positive and/or negative prompt words you use!

Changelog

v1.2 'Skynet'

• new training config leading to less overtraining, more flexibility and diversity

• naming each version from now on after the training config used

• for more info see my training guide linked at the top

v1.1 'Hal'

• 27.11.2023 - renamed model name again, updated model description, and added two sets of custom prompts - reflecting my recent discovery that this model can actually output more realistic true-to-life low-quality photos than base SDXL as well as high-quality heavy post-processed photos and as such appears to work as more of a general "better photography" improvement LoRa than just a high-quality photo style LoRa, even if the results will still skew towards such results!

• 22.11.2023 - removed "Heavily Post-Processed" from the model name and description as this model is also perfectly capable of non-post-processed images, as the very last sample image shows

• new version naming convention: first the version number, then an AI from fiction: this is to have better consistency across different models which have different version numbers due to release date differences, but which all have the same underlying training workflow

• slightly reduced overtraining, particularly fixing the eyes and freckles issue, but also some other issues

• new sample images using Kohya's 'DeepShrink High-Res Fix' at 1536x1536/1920x1080/1080x1920 resolutions

• added a link to my new training workflow guide

v1.0

• Initial release - for now final release
