Google researchers have unveiled a new artificially intelligent (AI) program that has incredible denoising ability allowing users to "see in the dark."

Photographer Brent Hall recently went out to shoot a comparison video that a lot of Canon shooters are eager to see: the brand new EOS R5 vs the EOS R6, for astrophotography, at high ISO. Does the lower resolution sensor of the R6 give it a low-light advantage?

Given all of the overheating controversy and the intense focus on the camera's 8K and 4K video capabilities, you'd be forgiven for forgetting that the Canon EOS R5 is also a stills camera. But Gordon Laing at Cameralabs didn't forget, and he's reviewed this camera specifically for stills photographers.

Photographer Chris Lee of the YouTube channel pal2tech recently released one of the most straightforward technical explanations of ISO that we've seen. In this 12 minute video, he explains what ISO is and, just as importantly, takes on a couple of common misconceptions by explaining what ISO is not.

Is noise in photos always bad? It might seem like a rhetorical question with an obvious and universal answer: yes. But landscape photographer and YouTuber James Popsys begs to differ in an opinion video that will no doubt spark some debate.

Here's a 10-minute video tutorial by PiXimperfect that teaches how to add artificial film grain to your photos. Learn three ways to give your digital photos a film look.

After doing an astrophotography shoot and zooming in on the stars, and you may find digital noise spoiling the scene. Removal in Lightroom can result in less color in the cosmos, but using a piece of software called Starry Landscape Stacker software can make the final output much better.

As the saying goes, "There's no such thing as a free lunch." And it looks like this applies to camera tech as much as anything else. According to a new report, the Sony a9 had to sacrifice some dynamic range to reach the crazy 20fps speeds everyone is so excited about.

Pentax fans have been waiting for the full-frame K1 with bated breath, and the first impressions coming out of the review community seem to indicate they haven't been holding their breath for nothing. In fact, a new test report claims the K1's dynamic range can compete with medium format!

In a world in which photographs are primarily taken with digital image sensors, there are a growing number of photographers who are newly interested in film formats of the past. But why would anyone in our age of technological convenience still choose to shoot with analog film?

Ever wondered what's actually going on inside your camera when you take your ISO from 400, to 800, to`1,600 and so on? If you'd like to find out, this straight-forward explanation by Ian Gibbons of PanvistaProductions from 2012 does a great job of explaining the electronics behind the exposure.

As photography technology continues to improve year in and year out, the ISO ranges we’re capable of pulling quality images from are getting truly ridiculous. But as amazing as the improvements in ISO are, it's important to have an understanding of what ISO actually is and how you can make the most of these growing numbers.

It's those questions that Mike Wallace tackles in the detailed video above, as he breaks down that part of the exposure triangle that is all too often misunderstood or ignored altogether.

DSLRs and Compact System Cameras are becoming increasingly capable video capture devices in addition to being solid still shooters. But when it comes time to focus or zoom using the lens' or camera's built-in motor, you're often left with glaringly obvious noise on your soundtrack.

So far manufacturers have tackled this problem by introducing silent focusing motor lenses, but one group of engineers is taking a firmware-based approach that seems to work just as well (if not better) and might someday soon do away with zoom and AF noise entirely.

You've probably heard of cameras that can detect wavelengths of light that human eyes can't, and also cameras that can detect heat in a scene, but have you ever heard of one that can capture sound? That's right: scientists at the Korea Advanced Institute of Science and Technology have created a portable sound camera that's sensitive to sound waves.

Photographer Zack Arias created this video titled Signal vs. Noise to help his …

Astrophotography enthusiast Don Marcotte wanted to find out whether the Canon 6D or Canon 5D Mark III was more suitable for his area of photography, so he pitted the two cameras against one another in a few noise tests at his local camera store. He simply shot long exposures without any light (the cap was on) in order to see how much noise would show up in the frame.

Canon made a splash earlier this month by announcing its first EF pancake lens, the Canon 40mm …

The first sample images of the Nikon D3200 have just come out of Nikon France; and although they look great for the most part, the one low-light image confirms suspicions that Nikon may have gone too far putting 24.2-megapixels in the camera. More noticeable on the full-resolution photographs, you can tell that once the ISO is cranked up to about 1600, noise begins to play a significant role.

Japanese website mono-logue released this short 30-second video comparing footage from the Canon 5D Mark II and the new 5D Mark III captured at ISO 12,800. The difference in noise levels is remarkable (be sure to watch it full screen and in HD).

Last Friday an anonymous poster on the photography board of 4chan sparked a discussion that rippled into the blogosphere after freezing their camera to see whether ISO performance improves at lower temperatures.
