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…]
Earlier this year we shared a rumor that said Nikon’s next flagship DSLR, the D5, will have 173 autofocus points, a 20-megapixel sensor and a maximum ISO of over one million – the first camera to feature a seven-figure maximum ISO.
Whether one is trying to photograph far away objects with a massive telephoto lens or using a microscope to document the tiny creatures that surround us, the rule is simple – if you can see it, you can photograph it.
It turns out, however, that objects don’t need to be visible to the lens in order for the camera to “see” them, as a research team from Scotland recently demonstrated.
A first of its kind camera is able to spot and track moving objects around corners in real time using short pulses of light from a laser beam.
The kind folks over at Panvista Productions put together a great informational video aimed at helping us better understand ISO. Most of us already know that we can adjust exposure through ISO, but for many that’s about the extent of what we know about the subject. Panvista’s 9 1/2 minute long clip, however, goes far beyond the basics of ISO we learn in the beginning of our careers. The video gets right down to the nitty gritty as it shows us exactly what’s going on inside our DSLR or micro four thirds camera every time we adjust the ISO setting. This of course leads us into the topic of digital noise (ugh) and why it occurs (interesting). Overall, it’s a well rounded video that’s delivered in a way which is easy to understand and engaging.[Read More…]
