Three separate Comfy workflows in the zip for Dev 8,16 and GGUF.

1.       Primarily it exists to allow subtle grading/colour adjustments of images by comparison and adjusting Loras, Color Adjustments, Sharpness and LUTs.

2.       Adjust colour (temp, hue, brightness etc) , sharpness and apply LUTs to the image (these are film colour grading files but in this context they are more like an overlayed filter) and compare sampler/scheduler changes dynamically.

3.       Its workflow width was primarily set for an ultrawidescreen monitor.

The Workflow Consists of

It consists of 3 separate work units –

1.       Left - Produce image with space for 3 Loras, process the image via colour controls (contrast, brightness etc), sharpen image and add a LUT to the image (think of it as an overlayed Film filter) and changing the sampler / scheduler .

2.       Middle - Process the image via colour controls (contrast, brightness etc), sharpen image and add a LUT to the image (think of it as an overlayed Film filter) and of course the sampler / scheduler.

3.       Comparator for the above two images. Compare adjustments and changes between 2 images that use the same seed for a practically infinite amount of adjustments and changes or on just one image.

Features

Help

Notes on each of the points below are provided in the flow. How to access Lora keywords, where to get the LUTs etc.

Bypassing

All of the units and processes within them are bypassable via the Bypass node (top middle). Turn off the processes you don’t want at any time, even the subprocesses with the main unit (ie loras or colours/luts but still make an unprocessed image) . If you are only tweaking the Loras for example, turn off the second unit and comparator.

Seeds

Seed generator node (rgthree) operates the same as A1111’s, so you click on the recycle button the bottom and it will keep the same seed. This allows you to tweak the current image to your hearts content via the strengths in all the nodes.

Bookmarks

Each of the three working units have bookmarks with a zoom included activated by numbers on your keypad . They link to the 3 work areas as well as ones to the Prompt box and to a text box with Comfy hotkey reminders.

Loras

It will produce images with up to 3 Loras.

The Lora Loader nodes should retrieve the Tags/Trigger/Keywords for each model and add to a file called loras_tags.json . For some reason the Bypass switch in these nodes crashes the workflow, use the dedicated Bypass node switch instead or dropping strength to 0 .

Be aware, some Loras are not compatible.

Saving

Saving is setup to go into dated folders and images named with date, time and LUT name. It saves the original and the Lora/Lut picture with the Lut name as a prefix.

LUTs

I only have about 12 Luts in my folder or I have an overload. If you want more, a quick Google "free luts" will get you more than you can shake a stick at. There is a url for the Luts I am using in the LUTs note in the flow.

Be aware there are 2 types of LUT, 3D Luts are not compatible with Comfy's Lut loader (unfortunately they have the same suffix of .cube)
