Growing up in the shadow of the Eastman Kodak Company, photography has always been my passion. From the first time my father and I developed film to printing it in our basement darkroom. After completing university with a business degree, I pursued commercial photography for over 20 years, during film's heydey.

Sigma 24mm f/3.5 DG DN

Sigma 24mm vs. Leica 24mm Mini-Review – By JK Lockwood

The just-released Sigma 24mm f/3.5 DG DN is the newest member of the L-Mount Alliance. It joins their 35mm and 65mm DG DN compact prime lenses and the older 45mm DG DN (previously reviewed here).

Well, those clever marketers at B&H Photo in NYC kept reminding me that I once had an interest in it, so I recently acquired one for $119 USD. For that kind of money I just had to try it!

Metering for Film, Understanding the Basics of Exposure – By JK Lockwood

Shooting film is a challenging process for many new photographers, especially those used to the instant feedback of digital cameras. Modern DSLRs are precision instruments that quite scientifically gather light. Film however is a bit more mysterious. The complete lack of feedback from film, plus multiple film stocks (which all respond differently to light) only adds to the complexity. Additionally, properly exposing color or black and white negative film requires a metering technique that is opposite of exposing a positive image. Permit me to explain.
