A Study in HDR 2 by Okavanga A Study in HDR 2 by Okavanga
This set of three images, A Study in HDR 1-3, shows the results of high dynamic range imaging followed by tone-mapping for an interior scene lit by halogen lights as well as ambient light. The first image is the mid shot of 11 exposures, each approximately 1 stop apart. This shot is then the camera's automatic best exposure for the scene. The full EV range turned out to be 13.4 stops, slightly more than the Canon 5D Mk 2 working range of 11-12 EV. Auto White Balance was used throughout and the camera set upon a tripod. Manual mode was used to allow the large number of exposures to be made. The software used was Canon's Digital Photo Professional v3.9.3; Photomatix Pro (64-bit) v4.1; and Picturenaut v3.2 from HDRLabs. Apart from the HDR software the only significant post-processing was sharpening (via DPP) of the tone-mapped images followed by scaling down for posting.

The second image in the series is that from using Photomatix Pro, with its default settings. The third image is that from Picturenaut, using the Adaptive Logarithmic method and adjusted to my best eye.

This second image, that from HDR and tone-mapping via Photomatix Pro brings out the dark areas very well with the carvings, seat, printer and computer now seen with considerable detail. There is even some differentiation in the area of the light bulb of the main lamp. However, the shape of the light bulb (one of those spiral types) is not seen here. It is seen as such in the preview window of Photomatix Pro, but does not translate upon processing. The colour balance has altered slightly and is more what my eye sees. In particular, the colours in the prints have been rendered reasonably accurately.

Yes I see what you mean the detailing is immense.....especially the cats :D:D. I like that you can see all the wires in the computer and the same picture on the monitor make it a bit surreal :D:D

Well spotted re the computer image, Linda - how did I do that I wonder? I think that in certain circumstances this sort of approach may be justified, but there is a great deal of work involved in setting this up.

Cheers

Must be magic :D:D:D luminance HDR crashes if I try to use full size image, who knows what it would do if I tried to process 11 of them :D:D I have bought photomatix now, but I'm not so keen on it for some reason. I think it does a better job of making an image look realistic but I still prefer luminance :D:D

I never tried the old "Luminance" with any more than 5 shots as I recall. I would have thought that any modern version ought to be able to cope with 11. I must go look at it again when I have time.

The latest Photomatix Pro has all these built in presets that you can browse through or use as starting points. I usually end up saving a set of parameters that I have developed and then using that on other images. I can sympathise if you feel that you are not so keen on Photomatix; you develop a liking for the quirks of some software, and miss them when you change. I try to see these different packages as tools for use in appropriate circumstances, although Photomatix does, for me, have that all round capability.

Cheers

For me what the Photomatix 'lacks' is the ability to do that really OTT detail thing that the Mantuik 06 does so well. It sort of has the ability to make photos look more like game graphics and gives it a really surreal feel. I have used Photomatix on a couple of my pics and then Topaz Labs to up the detail, I may need to start doing this more often as Luminace is constantly crashing for some reason. Your right about the tools fitting the job though, i took an autumn woodland scape the other day and used photomatix as the OTT look was out of place and it needed a more natural look. I really like the Cartoon (ish) look that some people apply to farm machinery and the like but haven't found that one yet!! :D:D:D

Hi Linda - yes - there are differences. Photomatix does have all these presets that you can use, but at the end of the day, it is us who decide what to do. I'm a fan of Mantiuk, but I think Luminance is the only package that uses it.

Cheers

Thank you, Pamela - It is the best of the three in terms of information content and shows the power of HDR and tone-mapping. It also shows why Photomatix is the leading HDR software. I was particularly happy with the colour balance - my study does look like this, perhaps a tad less vibrant.

Cheers
