Tuesday, May 27th: Merit and Adjust

Marty Grivjack, knows what it takes to create a merit image and you should too.

Entering your local, state, district or international competition is one of the best ways to push yourself to be more. And you'll learn where you stand—how your photography matches up with your peers. Marty will talk about the 12 elements of a merit image, and how to incorporate them into your daily photography.  Even if you don’t compete, your photography will only improve if you shoot and edit as if every images was going to competition.

Bring images on a USB drive that you would like to have critiqued.

During our Social hour, 5pm to 6pm:

Auto-focus Micro measurement and correction.

Have you ever looked at one of your portraits and found that the ear of your subject was in focus and the eyes were not.  Are you concerned that maybe your lens are not “spot on” and providing razor-sharp auto focusing performance.

Bring your camera and lens to Tuesdays meeting and during the social hour, 5 pm to 6 pm, have it check with a Spyder Lenscal target.  

The Problem:

 Photographers have enjoyed the benefit of autofocus for 25 years now, but many still struggle with its accuracy and repeatability. Auto-focus is a great convenience, especially in fast shooting situations. But typically the first step in reviewing files from a shoot is tossing all the images where the focus isn’t quite right. This can be motion blur or other issues, but one of the most frequent causes is auto-focus error. We tend to blame this on the camera choosing the wrong object, or the wrong point on the object as the focal point, but there is another possibility, one we hate to consider, given the price of the hi-end lenses we use: the auto-focus of our lens may simply be off. When you take a simple shot of a flat object perpendicular to the camera, and it still isn’t quite as sharp as it should be, you have to accept that this may be the cause.

The Solution: 

Many newer DSLR cameras now offer a method to correct this issue: they allow you to store auto-focus correction data for several of your most important lenses. This feature is likely to become more common, and appear in other camera types.  Spyder lenscal™ provides a fast, reliable method of measuring the focus performance on your camera and lens combinations. It allows photographers to obtain razor-sharp focusing or check to see that their lenses are working at their peak performance.
