According to recent reports, two new features are coming to WhatsApp. It looks like we’ll soon be able to share photos and videos at their “best quality.” In other words, it’s possible that WhatsApp will let us send them without compression.
This post will probably upset a few of you. Don’t care. Lens compression is a myth, I’ve been saying it for years, but when I try to explain why, peoples’ eyes start to glaze over. This video from Dave McKeegan, however, explains and demonstrates the principle wonderfully. Although, as Dave says, it really doesn’t matter.
Dave does go very in-depth into explaining the technical side of why lens compression doesn’t really exist, and if you’re not technically minded in the least, you’ll probably want to watch some parts of the video two or three times to fully understand what the demonstrations… uh, demonstrate. But it’s worth sticking with it. The better you know the principles, the better you’ll be able to use your gear.
Most the time when I am out doing landscape photography, I have a Canon EF 16-35mm f/4L IS and Canon EF 70-200mm f/4L IS with me. On roadtrips, I try to bring my Canon EF 100-400mm f/4.5-5.6L IS II – it’s a fantastic lens with great image stabilization and impressive image quality. Unfortunately, it is a bit too big and heavy for me to bring out more often!
I believe you already know that “zooming with your feet” and changing the focal length can affect the relationship between your subject and the background. In this short video, you can see the effect of both coming close to the subject and changing the focal length, and how it affects the final look of your image.
Instagram is notorious for destroying the quality of videos posted to your feed. You spend all this time editing a video in Premiere Pro, Resolve or whatever only to have it destroyed by recompression algorithms. It actually puts many people off posting videos to the platform at all. But all is not lost.
Filmmaker and YouTuber Daniel Schiffer believes he’s cracked the problem. And looking at his Instagram, it seems that he may have done just that. He doesn’t look to be having quality issues at all. In this video, Daniel walks us through his process from the rendering on the desktop to pushing it out on Instagram.
PSB files are Adobe’s answer to the 2GB file size limit of PSD files, the standard Photoshop Document, and something which most photographers will likely never have to deal with, but the big issue that plagues them can also apply to large or complex PSD files, too.
PSB files are something I only ever have to worry about myself when I’m making 100MP+ medium format film scans, but for professional retouchers, a 2GB document can be hit really quickly, and regularly. One thing that’s bothered many of them for a long time is how long it takes to compress and save out those huge files.
