Learning how to put together prompts in Daz AI Studio is like learning a new language.
The idea of this thread is to help each other out when we are stuck with our prompts.
You have a great idea for an image in your mind?
You need help to phrase it in a way the AI Image Generator understands?
Ask away. Someone on this forum may have an idea.
Anyone can ask and help out...

Curated lists by Bunyip02:

- Describe your basic image idea with as few words as possible
- add one more word and observe how the image changes
- combine a subject with two or three additional objects, a background, a lighting style
- the more words you use to describe your image the less effect each word will have
- words at the beginning of the prompt are usually of higher priority

How do you make animals look like toons?
Add the one word that changes the style
+ toon
Add additional words that reenforce the style
+ fluffy
+ cute
Using words that are synonyms can strengthen the theme.
At some point adding more words that affect the same area will not anymore make a huge difference and may have unwanted side effects.
One could argue that the squirrel may look more cute. But it also looks less fluffy now...
I ususally don't use more than 3 attributes for one object.
Mix similar animal shapes together
You can change different parts of the body by morphing them into a feature from another animal.
+ bunny ears
This works best if the base shape of the animals is similar...
It is a matter of trial and error to stumble upon combinations that work...
This part is constantly throwing me, whether Daz or another app. I keep wanting to know if there's a cutoff, and if so, where it is.
Rephrased several times. Hope this version makes sense.
Cut-off point
Some guides talk about a limit of tokens after which inputs are not anymore evaluated.
That token limit for SDXL is indicated by others at ~ 75 tokens.
(Never counted it myself. )
Words compete for dominance in the same area
Some words may affect the whole image. Other words may only affect a small area.
Words that affect the same area "compete" with each other.
Place the words that should have priority first.
The longer the prompt gets the higher is the chance that a word at the beginning of the prompt already "claimed" an area of the image.
The noise in that area is not anymore reshaped and the word has no effect even though the cut-off point was not yet reached.
Examples:
Both the jacket and the shirt occupy the same area.
Sometimes a closed jacket is generated and the shirt is not visible.
If you place the shirt first sometimes the jacket may not be generated.
Word order does not matter because object areas do not overlap.
Absolutely, the words before the first comma are generally the most influencial.

Thanks Bunyip02. I added your link to the first post.
Curated lists of prompts are a great starting point to experiment.
Add your own words, observe what changes.
Remove some words to check if they AI Generator recognizes them and alters the image in your imagined direction.
There does seem to be a word limit that is allowed into the prompt field here at Dazai.
Can you write prompts in Daz AI Studio in other languages?
I just entered some words in german and was surprised to see matching images generated.
A quick google search showed that during the SDXL base model training some images may also have been captioned in german, french, spanish and other frequently used languages.
Based on that prompting in different languages may work for common concepts but not yield the expected results with more advanced descriptions.
Given that some of the first functions for AI was spell check and translations, it makes sense it understands various languages and even mispelt words.
Why does the Angela 9 LoRA sometimes generate white women?
LoRA usually are not just an on - off switch.
To activate them you also need to add the triggers to the prompt - tokens, words that were used in training.
The base triggers for character LoRA are
In case of Angela 9 an additional trigger can be "dark skin".
A different character in the same LoRA with another trigger?
In Daz 3D Studio it is possible to apply a different texture to the Angela 9 shape.
I am not sure if what we see here is a version of the Angela 9 shape with a white skin texture.
In that case the Angela LoRA could have been trained with a second trigger like "pale skin"
a default checkpoint face
Or - this could just be one of the "default checkpoint faces" you get when you enter certain token combinations in the prompt.
In any case, that face triggers consistently when you combine Angela 9 with "pale skin".
What happens if we do not use trigger words in the prompt?
###
The developers who create Daz AI Studio may be able to provide some background information on such questions - to prevent speculation.
How can I make characters look older?
You can make characters look older by adding "old woman" to the prompt.
You can also get more specific by adding an age - "30 year old woman", "70 year old woman".
Edited: I split this up into two posts - may be easier to link when the same question shows up again later.
You have made an interesting discovery linvanchene. Why there is variation in the influence is worth further investigation.
I used your prompt with the "pale skin" keeping all other things equal, and each character's LoRA influenced in various ways the output, except for Angela, and perhaps to a lesser extent Wang.
That is an amazing overview, First Bastion - it illustrates that you can get feminine versions of male LoRA by using the token "woman".
This made me try this in reverse with "man".
kept the prompt the same:
masculine - feminine ?
Edited after trying it again.
I was not able to replicate consistent results when trying to "gender-swap" the LoRA.
When using the token "man" with Kala 9 sometimes still a feminine version would be generated. etc.
We probably would need some feedback from the developers if masculine and feminine versions for each LoRA are
What are styles?
A style is a token that influences the image generation in a massive way.
It can have effects on the color scheme or on the shape of objects.
Genre
You can find some examples in this blog entry:
Daz AI Studio: Prompt Engineering Guide - Daz 3D Blog
Just adding that one word can influence the clothing, shapes, buildings in the background.
Other examples:
Synthwave
This prompt includes other tokens that influence the image
Isometric
Can be a very specific style on its own. In Daz AI Studio it mostly shifts the perspective similar to "view from above".
If you search the internet for "styles for Stable Diffusion XL" you may find plenty of inspiration.
Which are your favorite styles for Daz AI Studio?
xy driving a [enter vehicle name here]
I looked up the prompt I used on those photos with a driver in a car - you may need a lot of rerolls to get a useful one.
Depth ControlNet would be extremely helpful at this point to block in the base pose.
