My first HDR

Finally, I made my self my very first HDR picture! It wasn't a bright day when we arrove in London, and all of our "normal" picture looks so bleak and dull. Then we decided to try an HDR shot. And here is the result. (Below : London Natural History Museum)

To those of you that wonder what is HDR?
HDR stands for high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.

How to take HDR picture?
HDR picture consist of minimum 3 individual picture taken at different exposure (say -2,0,and 2). And there is photoshop/GIMP techniques to merge the picture in order to create HDR effect. It is highly recommended that you use tripod to do this to avoid any misalignment among the pictures.
I follow a simple step by step HDR construction at this site, which also will give you a better understanding on what and how HDR works. I suggest that you do more than 3 exposure bracket for a better result.
(Picture of the ball is taken from wikipedia.)

Unfortunately for me, because we had no tripod at hand that day, we just have to rely on fence or pole to keep the camera on it's position and took 3 exposure (marked as -2,0 and 2).
Right, this is unrelated to HDR, but I can't resist to show you the beauty of this museum. How can a thing this nice can come free in this country?

These look lovely . I am so glad you did them the correct way and didn't you those awful HDR photoshop action.

Well done. I never carry a tripod. It gets to heavy for me to carry by myself with the rest of my equipment and kids stuff.

Stardust said...

Oh the pictures are AWESOME!!! I want to travel London again!!

Now HDR sounds like some mammoth theory to me, I really need time to digest all that! ;P

@Ellena : Give me a shout when you are coming :-)

@Liss : I use GIMP (not a true HDR) and GIMP is not as advance as Photoshop. Talking about tripod? I guess carrying it is my biggest nightmare.

@yadkin, Char & Cath : thanks!!!

@LittleKiwis : hey, share the result when you have them :-)

@Hippo & Merryn : if you think about to go to London again, give us a shout and we'll let you know where is this :-)

@Stardust : I am not a big fan of HDR myself, but something told me that I have to try it at least once.
