Light field camera
I downloaded the latest RawTherapee and converted a Canon G10 image with RT and ACR5.2. I found RT very unpleasant. So slow that changing sliders is agony (and I run a very fast core duo with 8GB RAM), controls that make little sense with scales in the thousands, and hyper-sensitive to sharpening.
What is an aperture? The aperture is the name used to describe the size of the diaphragm (the opening, or hole, which allows light through to the sensor). Apertures are measured in F-stops. F-stops are measured in incremental, numerical steps but to make things a little more confusing, the higher you go, the smaller the hole which lets the light through. Which, even though it may seem a little odd, means by selecting a higher number less light will be let through onto the sensor. For example:
In this post, Steve Berardi from PhotoNaturalist talks about three ways to get better control of autofocus. Sometimes autofocus can be really annoying. For some shots it’ll focus on the right part of your subject, but then the very next shot it may choose to focus on something far and away into the background. Sure, you could avoid this problem by always using manual focus, but autofocus is great when you need to focus quickly or when you’re photographing a landscape and you need to focus on a certain spot in the scene.
