positive prompt of "four fingers and one thumb" = this
Negative prompt of "five fingers" = no fingers at all
negative prompt of "badly drawn hands" = no hands at all
(note = I am using crayon ai for100 percent free since I obviously do not understand prompts)
Sorry PhoenixRising1, I Have Never Used Crayon AI, So Cannot Comment On Your Results, All I Can Say Is There Is More At Work Here Creating AI Images. I Have Tried 2 Other Prompt To Image Generators, And Some Work Better Than Others. Negative and Positive Prompts Are Only a Small Part.
Example= I Can Get Sometimes, Very Different Images Based On The Same Prompt, If I Choose To Change My Model, ie (there are several Including, Dreamshaper, Stable Core, Ideogram, SDXL, Real VisXL, DALLE) Each One Giving A Slightly Altered Image Based On The Model.
The Same Is True For Style Pre-sets , As There Are Even More, Things Like, Vivid, Mech, Photo, Realistic, Hyper Real, Striking, Anime, Vibrant, Colour Painting, Epic, Abstract, CGI, Modern Comic, Cubic, Pop Art Neo, Oil Painting, Cosmic, Sinister, And That Is Only Half Of What They Have. Each Renders Slightly Altered Results, Regardless Of Settings, Some Do Faces Better, Some Do Hands Better Without Negative Prompts. None Are Faultless Giving Perfect Results. Usually, The Higher Cost Pre-sets Like DALLE-3 , Give Much Better Results, Like Most Things, You Get What You Pay For.
New Corrective Tools Are Being Released To Solve Some Issues, Not Long Ago The Site I Use Gave Us Face Correction In A Couple Of Clicks, To Save Users Who Find Negative Prompts Difficult To Use, Maybe We Will Soon Have Hand And Feet Corrective Tools As Well, The Site Is Very Progressive, So I May Never Need To Even Go Down The Negative Prompt Learning Curve, Which Would Be A Great Thing For Peeps Like Me Who Struggle With Learning New Things Due To My Vascular Parkinsonism Dementia.
