I downloaded this and tried out a few prompts like, "Mark Twain holding an iPhone", and got back an image of Mark Twain - once in some surrealist nightmare fashion and another more like a 3D render. Neither were holding anything, let alone an iPhone. Cranking up the DDIM slider didn't seem to do much. Trying the same prompt on mage.space (see the creators comment in this thread) produced exactly what I assumed it would. Is there a trick to it?

Sometimes it's difficult to get certain combinations of things in a picture. It's easier if you provide a basic sketch with the components you want and use img2img (not sure how charl-e has it set up for img2img access, since I use the python original). There's also a knack for writing the prompts, generally you want to write your prompt as a list of short sentences. Don't make your prompt too short. Use concrete and clear concepts, beginning with your main subject, and describe their relation. You can also qualify the background, the mood, the material and the style among other things. Generate more than one sample - I normally go for five or ten samples so there are better odds of getting one that works, since the AI could try to interpret the prompt in different ways that make sense (but not to a human). I can't try it right now, but you might try something like: "A man is standing on the street, close up. The man has an iphone in his hand. The man is Mark Twain. Regular city background. Impressionist. Detailed." Tweak a few times and more often than not you'll end up with something satisfying.

You need to be more specific or you're gonna get a grab bag of 3D renders, stock photos, cartoons, etc. Like what were you hoping for? and add terms that will drive towards that.

  I wrote what I was expecting: The same type of results from the online tool I used. My comment was pretty clear, not sure why the two responses I got decided to give me advice about prompts.

    Because it depends on your online tool, Midjourney for example adds things to your prompts to make sure your images are better, OpenAI adds things to your prompts too. SD is much more raw.
