The Math of Digital Photography

This will be a three hour class with handouts. Bring your camera and portable computer.

Digital photography is fraught with math where you know it or it - embrace it or avoid it.  At least being aware of the underlying concepts will help you make better decision on camera settings and post processing.

  • What exactly is DPI?  What is Resolution? What is a Megapixel? What is Aspect Ratio?
  • How do I resize my images to meet a DPI/Size Specification?
  • Can I make an image Larger? What happens when I make an image smaller?
  • Should I shoot in RAW or JPG?
  • How do I crop for printing at standard sizes or fitting a certain size Mat?
  • How can i use PhotoShop to plan an exhibit?

This class will answer these questions and more.  We'll look at the image size, canvas size and crop features in PhotoShop extensively. (also in elements) We'll demonstrate how to get an uncropped print that does not conform to a standard size at the discount printer.

OH . . . did I mention?  THERE WILL BE MATH.  Bring your portable computers. We'll do  exercises.

I'll also demonstrate a cool exhibit planning trick.

Attendees get a coupon to enter a future exhibit at the Darkroom Gallery.

    The class was great! It was very informative and the class size was small enough that we really had the chance to get help individually if we needed it. We had handouts to follow along with the lesson and worked on being able to figure out the formulas and concepts within the lesson not just read them.

    Ken's class was excellent. He took the time to cover many aspects of aspect ratio, resizing photos, etc. in a way that I will be able to remember it and practice the concepts. The tips on setting up an exhibition were brilliant. It will help me set up a couple walls at home with photos that I have been putting off for a few years. Thanks again Ken.

    Ken, I just saw the notice about this class. I don't have a DSLR, just a Panasonic DMC-FZ35; nor do I own a laptop. This is info. I could really use, but probably not right now. Thanks for offering it at such a great low price!

      Yes we can go over resizing in lightroom too. It's very simple.

      You can pair up with someone that is using the same software.
