One question I'm asked a lot is "Where does all the noise come from when my camera is set to ISO 100?" The answer is simple. The photograph is underexposed. What is ISO? Grain vs. noise Back in the film days, the ISO (or ASA as it was called then) setting was the sensitivity of the film in the camera. While grain existed in every image, high ISO numbers produced more grain because the film had to have bigger chunks of light gathering chemistry. Today, the same idea applies. ISO in digital cameras refers to the light sensitivity of the … [Read more...] about Photography 101: How does noise happen at a low ISO?
HDR (High Dynamic Range) processing of your photos by its nature can result in a lot of noise or graininess in your final image. While Macphun's new Aurora HDR 2018 for PC's does a great job overall reducing noise, there are still times when noisy areas appear in your processed HDR. This can be caused by many reasons, but most commonly it's due to your settings in camera (such as shooting at too high of an ISO) or any image processing you have done to your images before merging them in Aurora (such as exposure adjustments). Regardless of the … [Read more...] about How to Remove Noise with a Luminosity Layer in Aurora HDR 2018

How do I remove noise from an image? from Lightroom: Tips and Quick Fixes by Richard Harrington How do I remove noise from an image? Noise is often caused by shooting at a higher ISO.

If you look at your interchangeable-lens camera's menu, you'll probably find a setting for Long Exposure Noise Reduction. In fact, many cameras have this activated by default. It's a cool tool, and here's a simple explanation of how it works and when you might not want to use it. What's it for? When you do a long exposure, let's say something longer than one second, your camera's sensor is activated the whole time the shutter is open. As it's working, it's also generating heat, and that heat (as well as other stuff) can cause image noise. … [Read more...] about Long Exposure Noise Reduction (I’m Eating Crow)

Photographs are wonderful things, and one of their amazing characteristics is the detail we can see in a picture. I'm pretty observant of details in face to face contact, so I enjoy the fact that my camera can record those details with great clarity and I can share them with others. However, digital noise sometimes obscures the detail and can create distracting color specs that I find really frustrating. In fact, when I first started photography, I wouldn't raise my ISO above 400 for fear that noise would ruin the images. I'd like to share with … [Read more...] about Hate Noisy Pictures?

I gotta say, in my grumbling transition to Lightroom (read backstory here), I am discovering more and more tools that I enjoy using. Recently, the tool I've been having fun using is Lightroom's Noise Reduction. In the past, I've often had to revert to third party plug ins to achieve effective noise reduction, however, I've found the tools within LR to be able to get the job I'm looking for, done. It's comprehensive without being cumbersome and allows for a great deal of flexibility and customization. The Shooting Environment The other week I … [Read more...] about Removing Noise with Lightroom
Grain is a word used in film photography to describe the fineness of detail a film or paper is capable of capturing. Landscape photographers typically want the finest detail possible, which comes from fine grained films. Documentary photographers and journalists may need faster speeds (higher ISOs) and will compromise detail for speedier films that have more grain. In digital, noise is the compromise we make for shooting faster ISOs, and the latest cameras biggest improvement is usually related to the detail maintained even at very high speed … [Read more...] about 3 Reasons to Add Grain in Lightroom
By When working with the Camera Raw dialog, you should always take the time to switch over to the Detail tab. Here you can take precise control over both sharpening and reducing noise. All raw images need sharpening. By default a value may be applied to the raw file based on a camera present. Noise, on the other hand, may not appear unless the image was shot with a high ISO setting. This is typically a problem when shooting under low light. To start, open an image into Camera Raw dialog. Click the Detail tab. Double-click the Zoom tool … [Read more...] about 88 Secrets of Photoshop — Add Detail in Camera Raw
I'm amazed at how well today's cameras handle low light situations; any DSLR you buy today can make a decent picture at high ISO's. Obviously, when we have the option we can control light and bring as much as necessary to make a high quality image at as low an ISO as possible. But if you're like me, you often find yourself in situations where the light is scarce and flash is not an option, but you still need to make a photograph. Maybe it's your kid's basketball game, or a dance recital, or a poorly lit rodeo. Tip #1 Get Over It High ISO (800 … [Read more...] about High ISO Shooting Tips
