Someone recommended that I use ImageJ to standardize the color in the image which I took with a Color Checker Chart in it. Does anyone know how to calibrate the image without having to buy plug-ins like the inCamera plug-in for adobe photoshop? Could you teach me how to use ImageJ to calibrate an image?

 I'm having a hard time trying to make the 3 standard colors (white, grey and black) in the photo to read constantly and near their true values. My file is in TIFF format.

Thank you! :D
