Library Gig: Know Thy Camera

September 4, 2012

I recently spoke at the Glenview Library. Since the admission price was right ($0), 94 people were in the room to hear my Know Thy Camera presentation. As you might imagine, the spread of both camera knowledge and equipment was vast. Presuming that would be the case, I addressed the mid-point of camera understanding, figuring that in a relaxed atmosphere, beginning photographers would ask questions without shame. That worked, and including questions, the presentation went on for 75 minutes.    Not bad for a Tuesday night in August.  Last Thursday, The Glenview Announcements local weekly newspaper ran a 2-page color spread on my time at the library.  I’ve added the link here.  //pioneerlocal.mycapture.com/mycapture/enlarge.asp?image=43268538&event=1518557&CategoryID=2297

Weekly Photo Tip

Get an Infrared Filter to create snow

 

Infra-red filter creates eerie snow effect.

Magnus, the faithful camera clubhouse cat, thoughtfully dropped a B+H gift card in my Christmas stocking. I used the card to order an Infrared (IR) filter which, as you will remember knocks out all wavelengths of light below the filter rating. In this case, all light below 930nm doesn’t make it through the filter, and the wavelengths that do make it require 2 1/2 minutes of exposure time. This filter is so dark red, the composing and focusing must be done before the filter is attached to the front of the lens. In addition to a tripod and ballhead, it helps to have gloves and a mug of some type of warm liquid to keep hands and insides warm while walking around behind the camera for those 150 seconds while the shutter is open.

IR filters come in varying strengths which affect the price. Mine wasn’t priced in the low-end promo department, but the effects it creates are both enjoyable and worth the price. Get one and see for yourself.

About Jack

A classically trained musician since childhood, Jack Carlson always had the “ear” of an artist. It was only a short step to develop the artist’s “eye” as well.

The portfolio of this certified photographer reveals images that emphasize mood and composition. Their purpose is to present a feeling in addition to portrayal of person, place or thing. Sometimes that feeling is nostalgia; other times it is serenity.

Each photograph tells a story.
