Okay, I have a digital camera converted to capture infrared light. I’m ready to go out and shoot pictures, right? My camera is ready–Is my lens? Light is bent when it passes through transparent materials such as air, water, and glass. However, different colors (wavelengths of light) may not bend at the same degree so […]
I’ve learned not to think when I run out with my camera to take some pictures. I may have a feeling about a place, a time of day, a sense of perfection or ruin in mind, but I am looking in my camera for something that just feels right. When I began as a photographer […]
I believe digital cameras, their sensors, lenses, and image processors have evolved and multiplied enough that I can buy equipment to make “fine art” for not a lot of bucks. However, I don’t think full frame cameras, professional lenses and the like are without value. They’re tools in talented hands for making extraordinary images. […]
Sensitivity is defined by the International Organization for Standards (ISO) in its abstract thus: “ISO 12232:2006 specifies the method for assigning and reporting ISO speed ratings, ISO speed latitude ratings, standard output sensitivity values, and recommended exposure index values, for digital still cameras. ISO 12232:2006 is applicable to both monochrome and colour digital still cameras.” […]
Today, I want to talk about time. The duration of an exposure can be very short, very long or anywhere in-between. Cameras can be set for exposures of one thousandth of a second or less, or of many seconds or minutes. Time, how long the shutter is open, or how long the sensor is recording […]
Sometimes I understand the way one person says things better than others. So here in my words are a few comments about camera settings that may help us know our cameras better. Photo editing software may allow me to compensate for less than ideal exposures, but better results come with good initial captures. Loosely defined, these […]
Having your camera configured to save in camera raw file format is like having a negative from which to work. All the data from light that reached the sensor is recorded in your file. JPEGs are smaller, but some data and development or editing latitude are lost in the process of compressing the files. Here […]
The naming scheme for digital camera sensors is derived from old television camera sizes expressed as the diameter of the tube through which light enters to strike the sensor at the end of the tube. The sensor’s diagonal measurement is about one third less than that of the tv camera tube so camera sensor diagonal […]
As I said in an earlier post, several years ago I resumed shooting and printing a lot. With some review at the Worcester Craft Center I went back out with my cameras and into the darkroom with less pain and more joy than ever. I changed formats from 35mm to 645 medium format when I […]
