# :material-tune-variant: Variations
|
|
|
|
## Intro
|
|
|
|
Release 1.13 of SD-Dream adds support for image variations.
|
|
|
|
You are able to do the following:
|
|
|
|
1. Generate a series of systematic variations of an image, given a prompt. The
|
|
amount of variation from one image to the next can be controlled.
|
|
|
|
2. Given two or more variations that you like, you can combine them in a
|
|
weighted fashion.
|
|
|

|
|
|
|
This cheat sheet provides a quick guide for how this works in practice, using
|
|
variations to create the desired image of Xena, Warrior Princess.
|
|
|

|
|
|
|
## Step 1 -- Find a base image that you like
|
|
|
|
The prompt we will use throughout is
|
|
`lucy lawless as xena, warrior princess, character portrait, high resolution.`
|
|
|
|
This will be indicated as `prompt` in the examples below.
|
|
|
|
First we let SD create a series of images in the usual way, in this case
|
|
requesting six iterations:
|
|
|
|
```bash
|
|
dream> lucy lawless as xena, warrior princess, character portrait, high resolution -n6
|
|
...
|
|
Outputs:
|
|
./outputs/Xena/000001.1579445059.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S1579445059
|
|
./outputs/Xena/000001.1880768722.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S1880768722
|
|
./outputs/Xena/000001.332057179.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S332057179
|
|
./outputs/Xena/000001.2224800325.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S2224800325
|
|
./outputs/Xena/000001.465250761.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S465250761
|
|
./outputs/Xena/000001.3357757885.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -S3357757885
|
|
```

## Step 2 - Generating Variations
|
|
|
|
Let's try to generate some variations. Using the same seed, we pass the argument
|
|
`-v0.1` (or --variant_amount), which generates a series of variations each
|
|
differing by a variation amount of 0.2. This number ranges from `0` to `1.0`,
|
|
with higher numbers being larger amounts of variation.
|
|
|
|
```bash
|
|
dream> "prompt" -n6 -S3357757885 -v0.2
|
|
...
|
|
Outputs:
|
|
./outputs/Xena/000002.784039624.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 784039624:0.2 -S3357757885
|
|
./outputs/Xena/000002.3647897225.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.2 -S3357757885
|
|
./outputs/Xena/000002.917731034.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 917731034:0.2 -S3357757885
|
|
./outputs/Xena/000002.4116285959.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 4116285959:0.2 -S3357757885
|
|
./outputs/Xena/000002.1614299449.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 1614299449:0.2 -S3357757885
|
|
./outputs/Xena/000002.1335553075.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 1335553075:0.2 -S3357757885
|
|
```
|
|
|
|
### **Variation Sub Seeding**
|
|
|
|
Note that the output for each image has a `-V` option giving the "variant
|
|
subseed" for that image, consisting of a seed followed by the variation amount
|
|
used to generate it.
|
|
|
|
This gives us a series of closely-related variations, including the two shown
|
|
here.
|
|
|
|
|
|
|
|
|
|
|
|
I like the expression on Xena's face in the first one (subseed 3647897225), and
|
|
the armor on her shoulder in the second one (subseed 1614299449). Can we combine
|
|
them to get the best of both worlds?
|
|
|
|
We combine the two variations using `-V` (`--with_variations`). Again, we must
|
|
provide the seed for the originally-chosen image in order for this to work.
|
|
|
|
```bash
|
|
dream> "prompt" -S3357757885 -V3647897225,0.1,1614299449,0.1
|
|
Outputs:
|
|
./outputs/Xena/000003.1614299449.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1 -S3357757885
|
|
```
|
|
|
|
Here we are providing equal weights (0.1 and 0.1) for both the subseeds. The
|
|
resulting image is close, but not exactly what I wanted:
|
|
|
|
|
|
|
|
We could either try combining the images with different weights, or we can
|
|
generate more variations around the almost-but-not-quite image. We do the
|
|
latter, using both the `-V` (combining) and `-v` (variation strength) options.
|
|
Note that we use `-n6` to generate 6 variations:
|
|
|
|
```bash
|
|
dream> "prompt" -S3357757885 -V3647897225,0.1,1614299449,0.1 -v0.05 -n6
|
|
Outputs:
|
|
./outputs/Xena/000004.3279757577.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,3279757577:0.05 -S3357757885
|
|
./outputs/Xena/000004.2853129515.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,2853129515:0.05 -S3357757885
|
|
./outputs/Xena/000004.3747154981.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,3747154981:0.05 -S3357757885
|
|
./outputs/Xena/000004.2664260391.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,2664260391:0.05 -S3357757885
|
|
./outputs/Xena/000004.1642517170.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,1642517170:0.05 -S3357757885
|
|
./outputs/Xena/000004.2183375608.png: "prompt" -s50 -W512 -H512 -C7.5 -Ak_lms -V 3647897225:0.1,1614299449:0.1,2183375608:0.05 -S3357757885
|
|
```
|
|
|
|
This produces six images, all slight variations on the combination of the chosen
|
|
two images. Here's the one I like best:
|
|
|
|
|
|
|
|
As you can see, this is a very powerful tool, which when combined with subprompt
|
|
weighting, gives you great control over the content and quality of your
|
|
generated images.
