simpler HDR on my phone



Continuing on with the HDR theme, which seems to be this week sub-plot. I was out walk (unusually without my DSLR) and notice an interesting cloud formation. Of Course I had my phone, A normal exposure would be ok but I guess an extended dynamic range HDR  might be better. So I used my HDR Camera app, which has been changed a little lately. It still takes and processes the three bracketed images on the phone, and has the big advantage that you don’t have to keep the phone exactly steady and it now has the more common interface where you pick the look & tone mapping from small thumbnails  I like the natural tone mapping but sometimes I might do light tweaks to the exposure and colour vividness. It still does this on the phone, so you can cross reference back to what you are actually seeing.

I’m sure there are a lot of HDR apps out there now, Yet for those, such as an artist, who might like to capture difficult subjects straight onto the phone as close to what they are seeing as possible, and check, doing everything on the phone is a big bonus. More traditional HDR approach are normally carried out some time later under different lighting and colour context so it can become a little more challenging to get the “feel” of the colours
