1st HDR photograph

MJG Uncategorized 8 Comments

HDR imaging is a fascinating sub-branch of photography that I just became aware of. HDR means High Dynamic Range, which basically means you have a photograph with a heck of a lot of information in it, spanning a range of lights through darks impossible to capture in a regular photograph.

Here is my first HDR effort- taken from my 3rd floor balcony.

Wikipedia has an interesting article on HDR– dating it as far back as the 1850’s, with a sailor/photographer taking two shots, one with the sky exposed correctly, the other with the sea. He’d then physically cut the negatives, splice them, and produce a single shot with the sea and sky as balanced as we might see with our eyes.

Apparently a decent HDR technique has been a holy-grail of still-image photographers for a long time- one which they’ve pretty much wholly acquired now, at a commercially viable level- what with everyone going digital, and the software easily distributed over the net. It involves a method similar to the sailors’, except all in a computer program. You take multiple shots of the same still-image at different exposure levels- in the above shot I took one for the sky, and one for the buildings. You plug those images into your HDR tone-mapping program, in my case Photomatix Pro 3.0, which I heard is probably the best, and it produces a composite which you then tweak back and forth until satisfied.

Here are the 2 images I used to create the composite:

Dark foreground, but the sky is well-exposed.

The sky is blown out, but the foreground is at a good light level.

You’ll notice in the final image I also ramped up the color and contrast some- it was a grey day and I neglected to change the filter to accomodate that.

I’ll play around with more digital images in my coming ruins articles, plus more upcoming shots of interesting Tokyo architectures.

  1. Funnily enough, I just came across this type of photography today myself!

    I might have to look into playing around with some of my own photos when I have more time. It makes perfect sense though – my digital camera is not quite good enough for complete tonal range, so taking several shots at different exposures and combining them is a great, albeit labour-intensive way.

    Hey Al- Yes you can do it with your digital camera, you just need the right HDR post-production software. In this case, Photomatix Pro. I think some cameras can do this kind of thing in camera- which is very cool, but probably only very expensive top-of-the-range models. Photomatix costs $99, but you can get a trial version from their website for free.

    Mike- Yeah I looked at that link- some of the stuff is amazing- though there are some photography purists who look on it as ‘cheating’. I don’t really worry about that though, and am looking forward to giving it a real go at the next haikyo I visit.

  3. Ha, I’m one of those purists! I’m not against HDR and even started to try it myself. I just wouldn’t want it to be called a photograph. I think it should be called an “HDR image.”

    They would be good to use as creative images in various print and online media.

  4. This isn’t going to work for a moving subject- or indeed- for portriature- or is it? Is there a way you can take all your different exposures at once?

    Jason- Yeah, it’s a fair point- it’s not a conventional photograph, it’s a digital manipulation.

    Tony- With a regular camera I think a moving subject would be impossible, though with portraiture, if you could get the subject to sit totally still- and of course you used a tripod- it’s do-able. I’ve seen one, it looked weird, but not bad. As for all in one shot- Jason who commented above told me about RAW images that higher level cameras can take- which capture much more light vs. dark information than a regular shot- thus allowing you to re-balance things digitally after-wards, much like an HDR shot.

  6. Interesting… I’ve been doing that with some of the pics on my photoblog for a couple of years now, using Photoshop. Didn’t know it had a name – HDR – nor that other people were into it. Cool.

    Tony – you can do a moving subject, but it takes more work. Just focus on the moving subject when he is there. Then take a picture of the background when he is not there, to get those colors right. You’ll need to cut and paste and blend, but it’s doable.
