The digital age and the ability to crop our photos however we want instantly has reduced the attention placed on aspect ratios. Nonetheless, aspect ratio has an important impact on many factors of your image, ranging from composition to printing. This excellent video tutorial features an experienced landscape photographer discussing the effect aspect ratio has on images and how to leverage it to improve the quality of your photos.
Coming to you from Christian Irmler - Landscape Photography, this awesome video tutorial discusses the use of aspect ratio in landscape photography. Modern digital sensors are almost always made in the 3:2 or 4:3 format, but that does not mean you have to keep the resultant photos in those ratios. While you can always crop in post, it is worth considering how you plan on framing the final image in editing, as this will allow you to account for it in the composition and minimize the amount of resolution you will lose when you crop to the desired aspect ratio. Check out the video above for the full rundown from Irmler, and try getting creative with aspect ratios during your next editing session!
