Resize the height in photoshop/gimp to 600px.

Then the file size should be much lower.

Here's my first attempt at HDR, top right didn't come out so good...

Not to say that isnt an HDR, but it really doesnt show what and HDR really does.

Here is one (I didnt take this):


This turned what would be a VERY contrasty photo into something with little contrast.

Without HDR, it would have a blown out sky if exposed for the street. So two exposures were shot, and thus combined.

Guess I will try it outside later today.

The Macro bug never bit me. I had the "OLD" Nikon 105mm f/2.8 and I used it mostly for portrait shots. I bought the 60mm f/2.8 and rarely used it for macro as well. I sold both to get a 105mm VR and STILL the macro bug didnt bite, pluse I felt more comfortable with the old 105mm, so I sold the VR for a 70-300mm VR. Currently looking for an "old" 105mm 2.8 or an 85mm 1.4.

BTW, HDR or IR is great for landscapes (NOT MINE):

No need for exposure blending/HDR shots.
Have a look at the pic below (not mine) of the difference between a shot without HDR and one with HDR on the K20D. On this camera, it's a built-in feature, no need for filters, multiple exposures (to combine in software later) or any of that, just turn it on and each shot is an HDR shot. Apparently there are three different HDR modes as well on the K20D, although I don't know what they might be?

The one on the left is "normal" while the one on the right is an HDR shot, straight out of the K20D, with no filters, software use or anything else.



I've scaled it down, so the details aren't super, but you can clearly see the difference it makes. Here is the page it's from, so you can see the bigger version. Personally, I think it makes all the difference, in this shot anyway.

I've tried creating HDR images using my RAW processor to over-expose and under-expose an image, then blending them both together in GIMP and the results do look good and give great detail in both dark and light areas, but it can be a bit time consuming, especially if you create more than just two differently exposed shots and merge them. The K20D takes all the hassle out of it and the results look good to me .

What do you think?

I think it looks alright- But aside from the shy in my opinion the first shot looks better. Shadows just fir the scene.... PERSONAL PREF alert!!! It IS cool though....


So: On cameras: I went to Wolf Camera today- Decided on Nikon. D40/60/80.... I MIGHT be able to trade a D60 for my dads D80....

Very promising indeed, but I'd like to see more examples. The one above doesn't have to much of a difference between the sky and foreground, I'd like to see if the K20D could produce an HDR a shot more like what ecoyd posted.

You can actually see, that in the non-HDR shot, a lot of the colours are so dark, they look black. See the bottom left section, which is the colour it's supposed to be the HDR shot, but essentially black in the non-HDR shot. See the cranes also.

There's a lot more contrast in the first (non-HDR) shot, which perhaps is more pleasing to your eye than mine? Personally, I find the second image more pleasing, as it seems more balanced and there is more image detail and colour detail.

There's not a huge contrast between sky and foreground, I agree, but there are loads of areas in the non-HDR shot where lots of detail gets lost in the darkness. In the HDR shot, you see so much more detail, as well as colour.

I'll have a hunt around the web and see if I can find any more examples .

Sorry for the double post .

I found this pic, from a review of the K20D, taken on a damp day in the UK.

The first (left) image is "normal" the second (right) is with one of the HDR modes switched on, called "EDR".



Here's the page it's from.

There's a bit more of a contrast here between sky and foreground in the first shot, which is balanced out quite well in the second. I think the HDR shot looks much better. Again, image details are more prominent and colour is more vibrant in the HDR shot. Just look at the lady's pink top in the left foreground and slightly further away, the hair of the two blonde ladies. The colour is much better in the HDR shot. This is all achieved in-camera, automatically, when the setting in turned on.

Apparently you can use this setting with RAW shooting, so if you prefer a bit more contrast, you could always dial it up a fraction or so in the "digital darkroom", if you wanted.

There’s a whole bunch of seagull shots here, from a guy using a K20D with the “EDR” function that gives you the HDR effect. Apparently the white of the seagulls was very bright and the shadowing dark, or at least so he says here. Although you don’t get to see a comparison, the shot’s do look good, to me at least.

I’m yet to find anything that looks much like what ecoyd posted, but the camera is pretty new, so it's hard to find many comparison shots. It was only released the first quarter of this year apparently. If I ever get the camera (which, as you know, I'm seriously considering) I'll have a play around and see what I can do in-camera, HDR wise.

If you like HDR shots though, there are some really nice ones (achieved manually I believe) here on flickr, tagged HDR and K20D. This one and this one are really nice (imo) but I doubt they were achieved with the in-camera HDR function.
