The purpose of this article is to clear up myths and misinformation about image exposure ISO, and noise. So, what is exposure exactly? Exposure is simply the amount of light reaching your sensor or film in a given amount of time. The amount of light reaching your sensor is determined by the length of time the camera’s shutter is open, and the size of the opening in your selected lens model.
The plan was to arrive at the lake for a morning of red-winged blackbird photography. I was awake way early, but decided to start up the coffee pot… and my day. I checked my weather app, wondering what yesterday’s snowstorm had wrought. When I saw it was only 9 degrees outside, the thought crossed my mind to back out! However, there were still a couple of hours of darkness remaining, and I hoped the morning sunshine would warm the air a bit, by the time we arrived.
There have been a rash of fake AI osprey pictures on social media lately. They are quite fantastic and almost impossible to identify as fake. However for a real osprey photographer, there is one telltale difference. All the osprey pictures showing up on the web lately show the great raptor with a perfect fish, perfect face with perfect eyes looking around at the scenery on his unexpected flight through the wilderness.
This post has been a long time coming. Last winter I loaded my old Canon A-1 film camera with a roll of Ilford Delta 400 to see if I like it better than the venerable HP5 emulsion. In addition, I will be testing out my new yellow and orange filters to see what effect they have on this film stock.
Thought I'd put together this quick Easter message YouTube video from the top of Grouse Mountain at the base of the Sangre de Cristo Range of Colorado!
It was actually foggy and spitting a bit of snow in Eleven Mile Canyon, but the wildlife were showing clear signs of the changing seasons.
It's difficult to keep up with all the new developments in my world in 2026! In addition to all the excitement in the mountains from returning bird species and new four legged babies being born in the wild, I have managed to complete my historical fiction and romantic adventure trilogy with the publishing of my latest, The War On Wildlife. I have also recently launched a new online sports and leisure magazine, which I will be talking about in this post!
It's taken a while to shoot a roll of 36 in the Pentax IQ Zoom 105 WR. It required a trip to the Rocky Mountain Arsenal coupled with a hike in the Garden of the Gods to get the job done! For this test I used a roll of Fuji 200 speed film. The WR stands for Weather Resistant, which is the main reason I also bought this version in addition to the IQ Zoom 200. This version of the IQ Zoom has no mode wheel, and very few external controls, to avoid as many entry points for dust and moisture as possible!
Another awesome visit to the Rocky Mountain Arsenal National WIldlife Reserve to test my newest acquisition, the Lumix DMC ZS50 camera with 24-720mm Leica glass! (I also took along my new Pentax IQ Zoom 105 WR film camera, but I haven't had those negatives processed yet, so that's a story for another time.
Episode Sixteen of my serial novel The War on Wildlife, has now been published and available for your reading enjoyment
