Infrared is a type of photography that appeals to some and not others, but it's definitely different.  I got into IR photography years ago when I bought a Hoya 720nm external filter for my old Nikon D70. I loved the results I got but had little understanding of what I was doing..ie: why I was getting what I got and how to control it.  IR to me then was what you get out of a 720nm filter.  I still like that look, but there is so much more. Like most people getting into IR I shot primarily landscapes with lots of trees, since that was where IR seemed to excel.   Post processing, which is absolutely essential in IR was somewhat of a mystery. I did it but without a lot of creativity.  

I eventually decided to acquire a converted camera to take with me as a second shooter on my travels.  I got a small Canon ELPH180 point and shoot full-spectrum camera with three filters, a 720, a 590, and a chrome filters.  Again..didn't understand much, but had a lot of fun and actually got some good shots...some featured in this gallery.  This camera taught me what the different cut-off ranges did, and allowed for more creative Post Processing.  As I traveled with that little camera the range of subjects also broadened considerably.  For me I saw IR really excelling in architectural shots, and black and white. Skies are always critical to me, and IR made them pop!

Finally, recently I converted a Sony a6000 camera, that had been my wife's travel camera, since she had switched to using her updated iPhone for most shots.  I converted the Sony to 590nm based on the thinking that I didn't much like the chrome look...that would need a full spectrum conversion...and 590nm with Post could give me about any look I wanted...easier to carry around on my trips as a second shooter.  I did eventually find a filter adapter to allow me to attach my old Hoya 720nm filter to the Canon, and then just for fun I purchased a 890nm filter.  So that is my "gear" at the point.  The Canon ELPH180 full spectrum and the Sony a6000 590nm with filters.

My opinion of the Sony as an IR camera...  I could not be happier.  I can now shoot in Raw, opening up all sorts of creative opportunities.  The camera is small and fits easily into my bike handlebar bag, or fanny pack.  Great choice for an IR camera.  The lenses are probably a more important consideration.  They are that for any photography, but especially for IR because of the "hot spot" issue.  Not wanting to break the bank, I stayed with the two kit lenses that the camera came with; Sony 16-50, f/3.5-5.5, and Sony 55-210 f/4.5-6.3.  While not top-of-the-line lenses, they are more that adequate.  High speed (eg: expensive) lenses aren't required for IR since most of the shots are at mid day, well lit and standing still.  I use the wider angle lens for 90% of my shots.  The hot spot issue is not unmanageable at wide apertures, unless you shoot close the the sun.  Sun flairs are more of a problem with the external filters since one is 77mm and the other 58mm, both requiring filter step-up adapters which doesn't leave room for the lens hood.  Thats not a lens problem....that just means I need to spring for new filters that fit the 40.5 filter size.

One thing I haven't tried as of this post is long-exposure shots.  With my filter adapters I can add ND filters.  Will have to try that.
