No matter how hard you try, your sensor will eventually get a few specks of dust. Now, you have two options: clean the sensor, or clean the photos by removing the dust spots in post-processing. If you prefer the second method, this short video by Benjamin Warde will show you how to make sure you haven’t missed a single part of the photo.
When you are out shooting, you can sometimes end up with plenty of photos that vary significantly in exposure. Adobe Lightroom published a short video tutorial on their YouTube channel to help photographers match exposure on multiple photos. The tutorial lasts as short as 60 seconds, yet it gives you a useful tip that will help you save a lot of time when editing photos.
