What does ETTR mean in photography?
exposing to the right
In digital photography, exposing to the right (ETTR) is the technique of adjusting the exposure of an image as high as possible at base ISO (without causing unwanted saturation) to collect the maximum amount of light and thus get the optimum performance out of the digital image sensor.
Is f3 5 good for astrophotography?
With the vast number of options available today there’s zero reason to even consider an f3. 5 lens for astrophotography/nightscape photography, there are far far far too many good to great options that are f2. 8 (and much faster) that don’t break the bank.
How do you shoot ETTR?
One method of aiming for a proper ETTR image is to take a photo, then analyze its histogram in-camera. If none of the histogram is bunching up against the right, you can increase the exposure. Stop increasing the exposure once the histogram says that your highlights are blown-out to white, and you’re good.
What is ETTR networking?
ETTR, Exposure to the Right, is a method for determining exposure with a digital camera that, when achievable, maximizes the captured signal-to-noise and, as such, provides the best underlying information from which to base a final image.

Is 2.8 fast enough for low light?
Ideally, the lens aperture should be f/2.8 or greater. Many zoom lenses have a fixed aperture of f/2.8, such as the 16-35mm f/2.8 or 24-70mm f/2.8. Although they are pricey, they are well worth the extra cost due to their flexible zoom range and their ability to shoot at f/2.8, which is ideal for shooting in low light.
Is 1.8 or 2.8 aperture better?
1.8 is actually more than 1 stop faster than f/2.8. If you are shooting hand held at 50mm and 1/60 f/2 with the prime you will most likely get a nice sharp shot.
How long does it take to catch star trails?
Shutter speeds ranging from 20-90 seconds are the best for star trails photography. I use a technique that takes a few hundred-star images, without trails, and overlays them on top of each other, creating a star trails image. You will learn this technique below.
How long does it take to get exposed to astrophotography?
between 20 seconds and 30 seconds
You want to use a long exposure time (slow shutter speed) when doing astrophotography, this will give your camera’s sensor enough time to record those little dots of flickering light. Usually, a good place to start is somewhere in between 20 seconds and 30 seconds.
