One of the things I love about the photography industry is that there's no shortage of myths and folklore. You'll probably hear a bunch of different myths and claims as you develop your career and I have to say it's a lot of fun.
In a recent video from two of my favorite photographers and YouTubers, Tony and Chelsea Northrup; they discuss some of the many myths that photographers still believe. Most of the time the myths that we believe tend to be rooted in something real or something that was once true. For example, many photographers still use UV filters which is honestly beyond me. There's a very good chance that no lens has ever actually been protected from impact damage by any UV filter in the history of photography. Also if you shoot with a digital camera then UV filters offer virtually no improvement to your images. Personally, the myth that I believed for a long time was that you should never delete images in-camera. This is quite obviously not true and something we can ignore.
Check out the full video linked above. Also, are there any particular myths that you used to believe? Are there any myths that even though you no longer believe, you still have trouble letting go of?
