Colour consistency between photos

    Hi all,

    Looking for some advice for a project. I need to take photos of skin lesions for a medical project.

    The photos will be taken in different settings and possibly with different cameras.

    I want to be able to process the pictures afterwards so I can make comparisons between colours from different images.

    I'm a complete newbee at this. I've done a little researching and was wondering about using a gray card in the photos so I can calibrate the colours afterwards? Is this the best way to do it?

    You'll need to put a calibration card in the shot, and adjust your exposure & colour to make that card's colour correct.

    What you are attempting to do is the same as a Clinic or Forensic Photographer, who has studied years to get that knowledge and skill.

    Where will you source these patients? If its in the public hospital system then there is legislation you will have to consider. You will require the correct paperwork in order to take these photographs.

    I would suggest you contact the Clinical Photographer who has authority in your area and discuss it with them. PM me if you need assistance.

    If you are going to be within different light sources and possibly different cameras, a colour chart would be the only way. This one is pretty small to carry around.
    And also, if possible, have the pictures shot in RAW. With the colourchecker, of course.
