Digital Negatives
This is the basic step by step process of making a digital negative for any process once you have your curve.
Download the curve you require from the Google Drive folder below and follow these instructions:
Open your image and edit it exactly how you want to look in black and white. Then flatten the image. Right click on the background and look for flatten image.
2. Convert the profile to gamma gray 2.2.
Edit -> Convert to Profile... -> Select the 'Gray Gamma 2.2' profile in the 'Profile' dropdown under 'Destination Space' and click 'OK'
3. Size the image to what you want it to be.
4. Apply the curve to the positive of the image (Kallitype - do this AFTER inverting the image to negative). Command M or Image -> Adjustments -> Curves.
5. In the 'Curves' window, click the gear icon and select 'Load Preset...'.
The gear icon is in the top center of the window.
6. Navigate to where the curve has been downloaded (usually the 'Downloads' folder) and click 'Open', then in the 'Curves' window click 'OK'.
The curve should reflect the loaded preset.
7. After the curve is applied, invert the image from a positive to negative.
Command I or Image -> Adjustments -> Invert
8. Flip the image.
Image -> Image Rotation -> Flip Canvas Horizontally.
