From Prompt to Picture: Comparing Text, Image, and ControlNet Generation Methods
This article will showcase the differences from Text-to-Image, Image-to-Image, and ControlNet for the same prompt.This image of Jane Lane from Daria (MTV 1997) will be used as the source image with control net and image to image. While prompt crafting, one option is to input your image into a free online resource such as Hugging Face's Clip Interrogator to extract a text prompt to match the image. For all examples in this article this prompt was used; Prompt: "Jane Lane, with short black bob haircut and multiple earrings, holding a paintbrush, gothic, woman, painting at easel, The background is simple and uses flat colors, evoking the distinct animation style of late 1990s adult cartoons. bold outlines, minimal shading, line drawing, She wears a red shirt with rolled sleeves and a white cloth draped over her shoulder. overall mood is quirky and creative, emphasizing alternative and artistic vibes"While this text prompt won't be drastically changing the image, it will provide the AI model with a general outline to recreate the image. Running this prompt through text to image with no image through Flux Kontext Alpha with 7 guidance scale, Using control net canny allows for precise transference of the outline and design, while Jane's eyes vary from the original, her hair shape is the same as well as her and the painting's pose. Elements like the eyes can be changed with further text refinement and settings adjustments, or the more advanced inpaint. This image was generated using image to image with .63 Denoise. Closer to 0 will match closer to the original image, and closer to 1 will generate images further away from the source image with more AI creativity. From my experience .5 - .8 is the range of recognizable. There is no preset one right or wrong way to create images, there are tradeoffs with each method. Text to image gives variance but does not match the source material. Control Net allows precision, but will maintain that same posture in each generation unless strength is lowered in settings. Image to image with denoise strength allows more adjustments to the image, the prompt, and the strength of settings. Once you understand the benefits of each method you can decide for yourself which is best suited for each image you are generating. The end goal for all users is best results with least amount of cost, understanding and utilizing the full set of model tools will give you the ability to do so. This is a simple example with simple results, you can extrapolate and apply these foundational generating settings to more advanced image creation. Remixing other AI images, using ADetailers, adding one or multiple LoRAs, using Control Net iP adapter, Inpainting, there are many ways to alter your images further. These methods cost more credits and can be challenging, it is recommended to research and have a basic understanding to get the results you want. Text to image, Control Net, and Image to Image should cover a large amount of use cases, you are able to create freely of any prior source constraint with text to image. There is the precision of matching shapes, vehicles, poses, animals, etc. with Control Net, and image to image can give you nearly photocopy subtle alterations all the way to unrecognizable remixes and every step in between. In my opinion a source image allows a sort of shorthand in facilitating you to convey the adage of a picture is worth a thousand words to the AI without a long verbose prompt. The AI will view the source image and will apply visual information to your new generations based on settings of strength scale. This allows you creativity with making your prompt if you choose unrelated to the image you are using as a source. You can prompt juxtapositions, conflicting elements, complimentary prompting, it's entirely to your desired image result. With dedication, creativity, and a passion for your efforts you should quickly be making the types of image results you want.
