Adobe Lens Profile Creator
Adobe Lens Profile Creator is a free utility that enables the easy creation of lens profiles for use in the Adobe Photoshop® family of products.
The Adobe Lens Profile Creator application is a characterization application. It is designed to model (characterize) the optical behavior of your chosen photographic system. Since it draws this model from a set of final output images, the model will ultimately represent the optical data as modified by the full photographic system.The Adobe Lens Profile Creator application is a characterization application.

Specifically, Lens Profile Creator characterizes 3 common types of lens aberrations* :
|An optical aberration that bends the light rays that pass through the lens, particularly along the periphery of the image plane, to create a distorted-looking image. The most common forms of distortion are referred to as ‘ barrel distortion ‘ and ‘ pincushion distortion ‘, because of the characteristic shape of the distortion as it appears in the image.||To go further

|Lateral chromatic aberration|
|An optical aberration that gives the appearance of color fringing, particularly along high-contrast areas of the image. This aberration is caused by different wavelengths that make up white light being magnified at different positions of the same focal plane.||To go further

|Light falloff at the periphery of an image, giving the appearance of a darker border along the edges of the image.||To go further

Adobe Camera Calibration Chart
Checkerboard charts that is photographed by Adobe to create a set of images to be analyzed in the Adobe Lens Profile Creator. Charts are located in the ‘ calibration charts ‘ folder of the installation repository.
Process of creating a custom lens profile
1. Capture a set of checkerboard images using your specific camera and lens,
2. Convert the set of raw format images into the standard Digital Negative (DNG) file format using the Adobe Camera Raw processor,
3. Import the raw DNG images (or the JPEG/TIFF images if you prefer creating lens profiles for the non-raw workflow) in the Lens Profile Creator to generate the custom lens profile.
4. (Optionnaly) Submit the newly created lens profiles for your lens to share with the rest of the user community.
