I read a lot of blogs, follow a lot of YouTube channels and subscribe to many “handy tips” postings that come into my mailbox daily. One such recent posting was from Tim Grey, a respected Photoshop expert and professional photographer.
Viewers had posted questions about the long standing belief that as you use lenses of longer and longer focal length, and compare the same scene shot through these different lenses, the apparent separation between foreground and background diminishes with focal length. In fact, this has been a long accepted “generality”, passed on from photographer to photographer, that scene “compression” occurs with telephoto lenses. But as with many things, the details get somewhat “blurry” (pardon the pun) and the specifics of the effect are often not explained. Continue reading “Scene Compression Uncompressed”
What are filters and why are they separate from adjustments? And what the heck is rasterizing anyway? Or the difference between “rasters” and “vectors”? And what is “rendering”? And of course, the single most important concept – non-destructive vs. destructive editing.
I come from a generation born before televisions were common in middle class homes. We relied on a radio for news and our only “social network” was the people we knew in the neighbourhood, at school, through our parents or through our church. Getting your name out there was done by word of mouth and by advertising on the radio and in the “yellow pages” or other print publications.
Experienced photographers who share their knowledge with new photographers spend a lot of time talking about composition and the “rules”. Leading lines, rule of thirds, negative space, etc. help to teach the eye what to look for when evaluating a scene. But they don’t spend a lot of time talking about why these rules matter at all.
