Record highs and a record stretch of high temps are being experienced in Western Arkansas and Eastern Oklahoma. It is too hot to take pictures. Sweating image sensors are bad. Well I do have motors to shoot tomorrow and a big thanks to Jeff Pryor and Pryor Marketing and Communications in Fort Smith for contributing to sponsorship of the upcoming Photographic Alliance of Fort Smith return of the Annual Photography Contest. This was a great contest with national submissions when the Photo' Alliance and the Fort Smith Art Center put this on years ago. I am happy to see a return and a good part of the non prize money will benefit the local Boys Club/Girls Club in support of the "Jim Hanna Photography Program". It is a great way for young and old to share in the Art of Photography.
To contribute or sponsor contact me, the Photographic Alliance of Fort Smith or the Fort Smith Boys and Girls Clubs. Watch for more information on the upcoming (November, 2011) contest. $500. "Best of Show" prize and other awards.
Enjoy the arts, with ice! John Cross

Sunny Sixteen- old rule Still Valid Today
The sunny sixteen rule states that a basic starting exposure (for film or digital still pictures) is the reciprocal of the film speed (back in the day ASA, now ISO) for the shutter speed at f16 for full sunny daylight exposures. Example bright sunny day no meter, or the reflective qualities would throw off a reflected (built in) light meter. You are using ISO 100, or your ISO is set at 100. Then your starting exposure would be 1/100 second at f16. or an equal value (EV). The lone lucky winner will receive a signed copy of my latest 4th of july abstract. Photos from this shoot will be post in a gallery at cross-photography.com by this Friday.
Remember to check your histogram for proper exposure. After the shoot is too late.
