Expositor is a Handy slide-Rule Based Exposure Calculator

Cool Stuff
Written By Bobby Parker

Expositor is a handy slide-rule based exposure calculator for photography. Pick the scene you're shooting, then slide the roller until your camera's ISO is lined up beside it, and every combination of F-Stop and shutter speed on the right will get you close to a perfect exposure.

For a more creative example, let's calculate shooting sports on an overcast day with a shallow depth of field (F4) to isolate the subject, and a fast shutter speed (1/500s) to stop motion. Match the F-stop and speed, then check the ISO value next to 'Heavy overcast day' to see how sensitive your camera needs to be. In this case, it's ISO 200!

Use Expositor in the field if you don't have a light meter handy, or use it to train your brain to be its own exposure calculator. Expositor is here to help you shoot great pictures!

Hey there, thanks for visiting my online portfolio. My name is Bobby Parker and I’m a Minnesota based illustrator who specializes in photo-real architectural renderings, and I’m not afraid to turn my hand to animation if the job requires it. While growing up in Illinios I always had a childhood interest in drawing and artwork that has stayed with me throughout my career in architecture. I received my architectural education working for some of the most talented architects in Chicago. I’ve worked on a wide range of projects, and pride myself on the ability to deliver a valuable and visually-appealing end product, no matter what the scope. For me, it’s essential to achieve a balance between quality and speed. 24 years after working professionally, I am still combining the fundamentals of art with the most current industry technology, to create incredibly realistic 3D architectural renderings. I love what I do, and I hope that it shows in my portfolio. Please take a minute to visit my work page and drop me a message if you have any questions
