I havent had a chance to go out and try taking shots but Ive been playing with it around the house (from inside a dark room looking into bright areas) and the results are definitely noticeable.


Pissed off Ive only figured out how to do this now, wouldve come in really handy on my recent trips over the last few years.

You can still do it now, use the Original & use Adobe Photoshop or Lightroom to get the -2 & +2 pictures needed from the original

A very good guide can be found here http://www.vanilladays.com/hdr-guide/

Personally, I like very subtle HDR images, but at least it points you in the right direction.

Must give this a go myself at some point, a nice shot of the tyne bridges would probably look great, just getting the light right would be a pain in the rear.

Doesnt that only work if youve kept the original in RAW?

In the process of getting some GND and ND filters as mentioned in that link.

Will be interesting to try both the filter and bracketed shots at the same time to see what kind of results it gives.

ND Filter will just make everything darker, and allow you to do longer shots, so lights will be blurrier :)

You need to over expose & under expose them first. I do that in Adobe Lightbox

Not sure about that version of PS.  I am using CS3 and there is an exposure option.  You can try just cranking up the contrast up on one and cranking it down on the other.  When you import into Photomatrix it will say they all have the same exposure, but you then can manually say which one is the + image and which one is the - image.
