I've been doing some interior HDR experimentation; it seems to be the optimal format for HDR work. I hesitate to call this architecture photography because the ultrawide by nature distorts the hell out of everything, but it's creating some good results. These were all done using multiple exposures (usually six exposures at 2 stop brackets), tripoded with cable release. Files were merged and downconverted using Photoshop.

Wow, quite nice. In playing with HDR, I too think it works best indoors.

Amazing photos indeed.

It's hard for me to imagine how these photos would have looked like withiut using HDR.

Impressive shots, and it looks like the HDR works really well for interiors as the colour detail is lovely, but yet not strange as can sometimes happen with HDR shots.

Outstanding work, the 3D effect of these is awesome. They seem like really advanced computer games graphics, the detail is amazing.

I agree these are great shots. I'm surprised it required so many exposures to get the full range.

Hi! HDR is short for "High Dynamic Range". Essentially, a camera captures much less exposure information than exists in a scene -- if, on a bright sunny day, you expose, say, for the ground in a photo, the sky will be white, or if you expose for the sky, the ground will be nearly black. However, our eyes do not see the world this way, as our cones and rods and brains are capable of collecting and processing much more exposure information than a camera can. In steps HDR. Essentially, you take several photographs of the same scene (in the case of the pics above, I used 6 photos each), each photo using a different shutter speed so as to capture as much information as possible. You then feed these photos to a computer program (Photoshop CS2 has one built in), which will assemble a single HDR image which will contain all of the information found in all of the photos. You can then downsample the image and, using curves, more or less tone the image however you please. You can find a tutorial in these two places:

So you use the shutter speed, not the aperature to adjust the exposure. I would have guessed the aperature...

What speeds do you usually use?

There is some software you can try for free from HDRSoft (http://www.hdrsoft.com/) which is kind of fun. Its also easier to use than Photoshop to do the Tone Mapping. The free software is fully functional it just leaves a watermark on your final image.

You use whatever speeds are appropriate to the scene -- you use a lightmeter (or the camera's built in lightmeter) to get a base reading, then bracket around that.

If you adjust the aperature, the DOF changes between each shot.

Very nice, good detail.

Any chance of posting one of the original pics to see how much of a difference the hdr makes?

great photos of those unbelievably beautiful interiors. however I am going to break from the rest of the comments on these photos because a couple of these photos look like the pillars have been layered on top in PS. reiterating previous requests, I would love to see an original exposure to see the difference.

I second that. I would be curious to see some of the originals.

This is the first HDR image on this site that actually works, and generally looks normal, with impressive detail, however, the lack of shadows leaves a technically impressive image, but lacks the added dimension of depth.
Still good work.

I agree with Les. For example in #5 it would be better if the upper floor behind the pillars was made just a little darker, without losing any detail. That would add more depth to an already impressive image.

Is that degree of adjustment possible in the software or do you have to accept what the program decides?
