Abnormal clothing, hand gestures, etc. are cropped out when possible. My rule of thumb is that if I wouldn't want the image to be generated by the LoRA, I don't include it in the dataset. There are some exceptions to this rule, but it is a good starting point to trim the dataset.</li><li>As many duplicate clothing items, facial expressions, poses, pieces of jewelry, etc. are excluded as possible, but it can often be hard to avoid this.</li><li>Images are cropped by hand and left at whatever # of pixels achieves the desired final image. They are kept to 3:4, 4:3, or 1:1 aspect ratios.</li><li>Many others have commented that 71 images is unnecessary, and that 20 or so will do. I prefer to be in the 40-80 range.</li></ul></li></ul></li><li>Captions<ul><li>All begin with "adriana chechik, a photo of a woman..."</li><li>I describe the clothing, jewelry, lighting, pose, angle, background, facial expression, makeup, and any other information I do not want showing up in the LoRA gens (abnormal hair color, for example) in sentence form.</li><li>I do not describe things I do want to show up in the LoRA, like eye color, hair color, skin tone, body proportions, etc.</li><li>I have experimented with adding a fake word "ohwx" to the captions with varying results.
