## Summary

This video provides a comprehensive guide to the image-to-image (img2img) tool in Automatic1111 for Stable Diffusion, covering image-to-image, inpainting, inpainting sketch, inpainting upload, and the sketch tab. It explains how to use an existing image as a starting point to create new images or modify specific parts.

### Key Points

- **Overview of Image-to-Image** [0:00] — The img2img tab lets you create a new image from an existing picture, pulling elements of composition and color.
- **Resize Modes** [1:29] — Four resize modes: Just Resize (stretch/shrink), Crop and Resize (crop to fit), Resize and Fill (fill blanks with colors), and Just Resize Latent Upscale (also upscales).
- **Denoising Strength** [2:29] — Controls how much noise is added; lower values keep image similar, higher values change more. Recommended starting point is 0.7.
- **Inpainting Basics** [4:33] — Inpaint allows painting over specific parts to change only those areas. Settings include mask blur, mask mode (inpaint masked vs not masked), masked content (fill, original, latent noise, latent nothing), and inpainting area (whole picture vs only masked).
- **Inpainting Sketch** [7:21] — Adds color selection to painting; used to add new elements like a scarf. Requires higher denoising strength (e.g., 0.8).
- **Inpaint Upload and Sketch Tab** [8:05] — Inpaint upload allows using an external mask (black for keep, white for change). Sketch tab lets you draw a rough idea and pair with a prompt to generate an image.

### Conclusion

The image-to-image tool in Automatic1111 offers powerful ways to modify or create images from existing ones, with inpainting and sketching providing fine control over specific areas.

## Transcript

in today's video I'm going to show you
everything you need to know about the
imaged image tool in automatic 1111
image to image sketch in painting in
paint sketch even in paint upload this
video has it all ready let's get started
the image to image tab is an essential
tool in your air toolbox it lets you
create a new image or new elements of an
image from an existing picture that you
provide there are so many powerful tools
here but let's start with the image
damage tab itself really you're going to
use this tool if you have an image that
you want to use as a starting point you
can use that image to pull elements of
composition and color into a brand new
image so I've got an image here that
I've generated earlier it's a portrait
of a girl on a city street I use the
sdxl base model to generate this image
but you can use any image you want an
existing photo a painting whatever so to
start we'll drop that into the image to
image box you can also send images here
from the text image tab just click on
send to image to image under your
generation at the top just like we would
for text image we can add in positive
and negative prompts if you did send
your image across from text to image the
original prompt will appear just like
you see here below the image box you'll
see all the settings we can play with
now a lot of these settings in this tab
are shared with text image so I'll only
touch on the image to image specific
ones here for a more in-depth
explanation of settings check out the
video in the description the First new
setting is resize mode use this if your
new image will have a different size or
aspect ratio than your original image
for example if your original image is
landscape and you want your new image to
be portrait the default is just resize
this will stretch or shrink your
original image to fit the new image you
create crop and resize will keep the
aspect of your original image and crop
it to fit the new canvas size resize and
fill takes the original image fits it
into the canvas and fills in the blanks
with colors from the input image I don't
see much use for this one but let me
know in the comments if I'm missing
something just resize latent upscale is
just like just resize but also upscales
the image if necessary note that this
setting is a bit tricky to get right and
there are easier ways to upscale your
images below resize modes you'll find
settings you're already familiar with
including sampling method sampling steps
your size and batch settings and the CFG
scale the most important setting here is
denoising strength stable diffusion
makes images by taking random noise and
converging it into an image based on
your prompt this setting will control
how much extra noise is added to the
picture and in turn will determine how
different the new image is from the
original lower settings won't change the
image that much and higher settings will
make bigger changes I like to use 0.7 as
a good starting point okay so now for
the fun part once you've sent over an
image you can start tweaking some
settings to refine your picture we sent
this image over from text to image so we
have all of our settings and the
original prompt now we could just start
tweaking our prompt here but bear in
mind that the entire prompt plus the
image will be used to create a new image
so if you aren't using the same model
seed and sampler from the original image
you may get some weird results so
instead we're just going to use some
simpler instructions to see how it will
affect the image so let's get rid of the
prompt and put in pink and and blue hair
and let's keep the same sampling method
and steps we'll tick restore faces and
we'll keep the default on just resize
and keep our Dimensions the same and
we'll set our denoising strength to 0.7
so we should see a bit of a variation in
our output foreign
seven that's had a pretty big effect so
if we want something a little more
subtle let's try lowering the denoiser
strength to 0.5
[Music]
and yeah that's a much more subtle
impact on the image
so you can keep on adding more detail
here and reworking things until you get
an image that you're looking for
when we use this method though we can
see that the prompt has had an impact on
the entire image the hair and eyes have
changed but so has the face and the
clothes let's say we just want to change
a particular part of the image and keep
the rest just as it is that's where in
paint comes in in paint is a powerful
tool that allows us to paint over the
specific parts of images that we want to
change this is especially useful when
you like the overall composition of your
image but you get one of those Cosmic
nightmare faces from the hell Dimension
just no to start you can click on the in
paint tab or just click in paint under
the image to copy the image over and all
of its settings so now we can just paint
over the particular part of the image we
want to change in this case the hair we
can use the settings in the top right of
the box to change the brush size or
clear our selection if we go wrong so
let's just paint over the hair and then
we can check our settings we've seen
some of these already so we'll keep
resize mode on default mask blur is the
amount of blurring that happens around
your painted mask lower numbers will
give you harder edges while cranking
this up will affect how many pixels
beyond your mask will be affected by
your prompt the default of four is
usually fine but feel free to play with
this if you're getting hard edges mask
mode determines what is actually changed
in the image in paint mask will change
the parts you've painted while in paint
not masked will change everything but
the parts you painted this is great if
you want to change the background or
large amounts of your image in one go
next you can choose the masked content
setting these settings tell stable
diffusion what method it should use as
its basis for generating the new image
part The Fill option will take the
impainted area blur it then generate
using that as its base the original
setting will use the original image
unaltered as its base to generate a new
image from latent noise will fill the
impainted area with new random noise
based on the seed number this can be
used if you want to result completely
different from the original Late nothing
will fill in the painted area with a
blend of the colors from the surrounding
pixels and base the generation of that
these settings will have a dramatic
effect on the output but if you're
making Minor Adjustments the original
setting will usually work great the
in-paint area setting is easily confused
with mask mode but they are different
choosing whole Picture Tells stable
diffusion to use the whole picture as
inspiration for the in-paint generation
while only masked will treat the Mast
area in isolation and not draw from the
rest of the image typically whole image
is the best setting if you want the
painted area to blend in but if you do
choose only masked you can change the
padding size right next to it which will
tell stable diffusion how many
neighboring pixels it should take into
consideration as inspiration for the new
generation and of course below that we
have the CFG scale and the noising
strength let's stick this on 5.5 and 0.6
and see what happens
now that looks pretty good but we can do
even more within painting sketch so
let's say we want to give our model a
scarf we can send this image to in-paint
sketch just like we did before we can
paint over the image but we now have the
option of choosing colors so let's go
with red here and just paint in the area
we want to add our scarf to
and in the prompt we'll just type in red
Woolen scarf
for this you usually have to bump up the
denoising strength so let's go to 0.8
and we can keep all of the other
settings the same as before
and let's hit generate
and yeah that looks pretty good for a
first try now you can keep iterating and
adding to this to really get the results
that you want the last in painting tool
is in paint upload now I'm not going to
go into too much detail because it's
more of an advanced topic but basically
you can create a mask in another program
like Photoshop using black for the parts
that you want to keep and white for the
parts that you want to change it's
actually a pretty powerful tool and if
you have the patience to get really
detailed it can be really useful
and finally that brings us to the sketch
tab if you're struggling to get the
image you have in your head onto the
screen using image to image or other
tools you can always flex your creative
muscles and draw it out here
simply drop in a white or black mask in
the Box provided and use the paintbrush
to sketch out your idea
use color to highlight the details you
want to show up and pair that with your
prompt and watch your sketch turn into
something incredible
there is so much more image to images
capable of and in my next video I'll be
showing you even more ways to level up
your art with the image to image tab if
