As a designer I insist that the value of IR photography is overestimated by so called ‘photographers’. We all know how many HDRi photos there are now on Flickr, 500px or Google+. The real reason of its popularity as well as love IR is poor skills in Photoshop.
The reason is that it is so popular it is so simple to get: a) all you need is just 2 or more still RAWs and b) a simple program with ugly UI downloaded from Internet. Any dummy can pretend being pro retoucher changing colours so much (and they do). Now you can take you dull photo and burn the colours so much that no one will be able to notice that there’s absolutely nothing in your picture behind the saturation and micro sharpness — they gonna simply have an epileptic attack caused by colours.
HDRi though is a very handy technics in skilled hands. The technology itself isn’t guilty for being used by idiots mostly. Some of them I would never give a driving license.
Unlike HDRi there’s no obvious advantage like recovering colours in dark/light areas. And all the photographers who have no idea how to work in Photoshop beside going 1-2-3 tutorials day to day say “you can’t achieve the same luminosity with Photoshop”. The should say “I can’t…” because a) personally I can and b) the IR luminosity isn’t that brilliant to stick to it. Shooting with IR filter is a nightmare because you literally can see nothing in viewfinder, cant set up proper colour balance, hard to focus and get ugly pink photo out of camera. It doesn’t really bring warmer surfaces brighter like in the movies. So why those ‘photogrphers’ keep using it and say it is unique? Simply because with the same pink image source they now can follow some 1-2-3 tutorial to swap it to b/w and colour.
So IR isn’t really that handy, just photo pips should learn more or photo editing but most of them a really hopeless. But well, now you can dilute your photo stream with alternatively looking photos now just in few clicks.
