In my previous article, I talked about cleaning your lenses and your camera. It's time to tackle a bigger, more complex subject: cleaning your sensor! If you shoot a lot, and especially if you shoot mirrorless, you definitely need to clean your sensor. If you have never done it, it can be quite intimidating, as you don't want to damage your camera. If that's your case, you may want to consider a professional sensor cleaning at your local camera store. But if you have to clean your sensor often (say, because you shoot mirrorless) or if you're … [Read more...] about Sensor cleaning: The ultimate guide

The idea of cleaning your camera's sensor scares most photographers half to death. The thing is, if you don't clean the sensor, you'll end up with spots in your pictures anytime you stop down the aperture a little bit, and it just gets worse over time. I know many photographers who are so nervous about cleaning their sensors that they won't even change lenses in the field for fear of getting some dust on the sensor.

What is “Normal” Focal Length?
Normal is defined as conforming to a standard, the usual, the typical or the expected. When it comes to photography, normal most often refers to the standard focal length lens on a camera. A normal lens sees about the same angle of view as the human eye. Let's delve into what normal means and why it's important. A "normal" lens is one whose focal length is the diagonal of the sensor of the camera. The sensor size is commonly known as the format. A full frame DSLR sensor is 36mm by 24mm. A cropped or APS-C sensor is typically 22.7mm by 15.1mm … [Read more...] about What is “Normal” Focal Length?

This allows you to set up a shot, specify the number of faces that need to be detected, as well as ad any … [Read more...] about Shoot Photos with a Motion Sensor
What is a Cropped Sensor?
If you're shopping for a DSLR or mirror less camera this season, you may hear the terms cropped or full-frame sensor pop up. Essentially, these are describing the size of the sensor within the camera. Full frame sensors are generally only found on cameras considered for pros, while cropped sensors are most common and can appear throughout product lines. Digital sensor sizes vary greatly between camera models and manufacturers. This is why the 35mm frame from a traditional film camera is used as a standard for comparison. This is often … [Read more...] about What is a Cropped Sensor?
