  • Photography and Generative Artificial intelligence

    My love has always been art but with kids and stuff I worked as a Linux system architect for over twenty years. The open-source world has given us so many things that we take for granted and I could not miss this extraordinary work done in generative images. In the short time I have been working with it AI has moved extremely quickly.

    The story of an AI apple

    Two Stable Diffusion AI apples were upscaled to a larger image and imported into Photoshop beta. Using the new AI generative fill I have replaced the background and edited it as I would a normal photo.

    But how did I get here…

    It started here.

    Multiple iterations with progressively more instructions until I was generating apples with some blemishes in light that were somewhat natural. I didn’t worry about the background as this would be replaced later in Photoshop

    Between each of the generations, small changes were made to the Stable Diffusion prompt to suggest a more natural apple

    Basic apple generated on Stable Diffusion using Epic_Realism model :
single green apple, realistic,blemishes, volumetric lighting, sunlight, Summicron, 50mm,

    This was the original apple to get the process started.

    Single apple generated on Stable Diffusion using Epic_Realism model :
single green apple, realistic,blemishes, volumetric lighting, sunlight, Summicron, 50mm, DOF

    I changed the prompt to include blemishes on the skin and ran some more steps. It kept doing this strange lighting where half the apple was lighter than the other. It did look more natural though

Steps 50

    This went too far and made me a nicely lit set of apples with bruises, but the apple at the back was deformed and had sprouted leaves. I decided that two apples might be simpler

    I picked this one as t the shape and skin texture looked the most natural I have also introduced:

    Lens type
    Depth of field
    Lens model
    Lens error
    Lighting type
    Lighting intensity

    It would have been faster to just take the photograph but there is an interesting side effect.

    I can apply the same prompts to other things entirely
