As a landscape photographer, perhaps you’ve been advised not to increase your ISO over 100 or 160. I’ve seen this piece of advice many times, and I know a few people who rely on it way too much. But should you really stay at the lowest ISO at all times? Should astrophotography be the only time you increase it? In this video, Mark Denney goes over two situations when using higher ISO is a must. As a bonus, he shares a useful trick to help you determine just how high you can go without fear of compromising image quality.
Whenever Canon comes out with new cameras, one of my most important real-world tests is determining how clean the images look at higher ISOs. I am not testing this for scientific reasons, I am doing this test because I shoot in low light quite often and want the highest quality images for my clients. I also thought that you and the rest of the world might be interested in this as well.
Many people get caught up in the number of megapixels that a camera has on its sensor, thinking that the more the better. What people may not know is that the more megapixels they cram onto a sensor, and the closer that those pixels are to each other, the more heat build-up occurs. This increase in heat can ultimately also increase the digital noise (graininess) in our photos.
Everybody knows the exposure triangle by now, right? ISO, aperture and shutter speed. Once you know your scene’s exposure value, you can just balance out the three to get a good exposure. And as you adjust one up or down, you need to adjust another in the opposite direction to compensate. Well, what if one of them isn’t really anything to do with exposure?
That’s the argument put forth by Chris Lee of the YouTube channel pal2tech, and it’s a compelling one. Back in the days of film, it was a little different, and your ISO really did reflect the sensitivity of the film stock to light. These days, though, with digital cameras, not so much.
Increasing the ISO value increases the amount of noise in your images. So, you may want to shoot at the lowest ISO possible. But is it a good idea to shoot at ISO 100 whenever you can? Michael Sasser believes it isn’t always the best choice, and in this video, he gives you his reasons why. Let’s see if you agree.
From the beginning of time, photographers have argued about the crucial stuff such as how to pronounce the word “bokeh.” And from what I’ve heard so far, most of them are pronouncing it wrong. But guess what: there are a few other photography terms that you’re likely saying (or spelling) wrong. In this video, Gerald Undone discusses these and explains how you should pronounce them and why.
If you’re just starting out with photography, the relationship between ISO, aperture and shutter speed is one of the crucial things to learn. However, it can be difficult to grasp if the concept is new to you. In this great animated video from Apalapse you’ll easily learn the relationship between the three parameters and how they affect the exposure and the look of your images.
How important is exposure in photography? What are the components of exposure? What is the “Exposure Triangle”? These are the questions I will attempt to answer in this introductory post about ISO, Aperture and Shutter Speed – the components of achieving a properly exposed photo.
Understanding the purpose and value of exposure is a must for photographers, particularly beginners who are serious about developing their craft.
ISO is one of the three major exposure settings in the exposure triangle of a digital camera. Of the three: shutter time, f/number, and ISO, it is ISO that is probably most misunderstood. Even more so than f/number. In fact, it is a common misconception that higher ISO settings will cause images to be noisier. In fact, the opposite is often true. Wait, what?
That’s right, higher ISO settings alone do not increase image noise and higher ISOs can even be beneficial to low-light photography. In this post, I talk about the craziness surrounding ISO settings, how ISO actually affects exposure and how to find the optimal ISO setting on your camera for astrophotography.
ISO is just one third of the exposure triangle. But, it stands out as the most interesting due to the fact that year after year, camera manufacturers are making it easier and more feasible to shoot higher and higher ISOs.
To get down to the basics though, Tony Northup has shared an ‘Ultimate Guide’ to ISO.[Read More…]
