Oh well, may as well get things rolling again!

Here are some HDR snaps from my local area, taken using a Nikon D80 in RAW and post-processed in Photoshop CS3 and Photomatix Pro.

There is a little bit of graining present unfortunately, owing to the original exposures not being in very good light and having to bump the ISO up a bit much to get the best tonal mapped HDRs, but they still haven't turned out too bad :)

(Edit: the right hand sides of these images are being cropped on the forum display for me... you may want to 'right click > view image' to get the full pics! )

Wipe my arse question - What is HDR again?

I assume to get the colours corect both (foreground and background) you had to do some funkeh effects. What did you do?

Also what camera you using?

Nikon D80 is almost exactly the same as a Canon EOS 400 in terms of spec price & review ratings
That's The REVEREND Dr. Kazza to you.

HDR is 'High Dynamic Range'

To get an HDR image you need to take three or five shots of a scene at different exposures, usually a normal shot and then one at +2/-2 stops.

To help you do this you can use your camera's AEB (Auto Exposure Bracketing) mode. For scenes with movement you can sometimes use a high ISO (if the light is good) + continuous shooting drive, but its usually best to cheat and take a single exposure and create the two differently exposed images using CameraRAW.

You then stitch the three/five together. The favourite for this is PhotoMatix, in which you generate an HDR from the tree (or more) exposures, and then use tone mapping to get the correct contrasts.

Final corrections can be applied with level adjustment layers in Photoshop.

A good guide posted in the forum pre-Rex was http://www.vanilladays.com/hdr-guide/

As I said in the OP these were taken with a Nikon D80... or possibly a D50, can't remember which they all came off. I've got some off a Canon EOS400D too that I might get around to posting sometime :)

Is that right? I thought the E400D was more similar to the D50

The most useful thing I find with the D80 is that it has more focus lock points.

Thanks for reposting this, I'm going to have a go at it and was annoyed the information was lost. Time to dust off my rusty SLR skills.

Folks might find this useful, a Photoshop HDR plugin

Might not work with Vista or Elements though.
