Default HDR (High Dynamic Range

A lot of photographers are experimenting with the HDR Technique including me and Roger_L.

Short explanation of the HDR technique:

Take 3 picture's which are exactly the same except for the shutter speed. Take 1 normal picture, 1 over-exposed picture and 1 under-exposed picture (1 to 2 stops). Use a programm like photomatix to convert these picture to a HDR image. What results is a picture with great lightning and detailing.

To give an example:

The first picture shows the picture with standard camera settings.
The second picture shows the picture wich is produced out of 3 diffrent pictures.

VU, Canon-camera's have an automatic function for that where you can define how many stops plus and minus you want (AEB). After pressing the releasebutton 3 photos are taken

Peter, Roger thanks for your replies!
This is a very interesting technique....definitely worth trying.

I am also experimentating with time-lapse atm. Does someone here on the board has experience with this?

Regards,

V

This is a very cool technique. But you have to be carefull, sometimes you see HDR pictures which are way overdone. But I think the examples above could have been a little bit more extreme.

When you use this technique to create a HDR picture (yes, there are other methods) you get the best result when using a tripod. The photos has to be exactly the same cropping. Some applications can correct this, but you'll always loose some sharpness. With a digital SLR (which can produce raw files) you ave another option: you can take multiple exposures out of one photo with a raw convertor. No more sharpness problems, but very nice results are possible!

A very nice tutorial about this technique is http://www.luminous-landscape.com/tutorials/hdr.shtml. He also shows that to get even better results you can use more than three photos.

Roger: most SLR camera's have this feature (even analog), but some can only take 1-stop-steps (what a word ) others can do more ranges. HDR is most fun with a little bit bigger steps.

Some nice HDR pictures by other photographers:



I even found a car, it's by a friend of mine

Hi all....

I found this picture of this BMW from another forum. Can you tell me whether this photographer used the HDR-technique or not .....

I'm not sure, he has done a lot with the colors, but it is not needed to be HDR.

With some HDR techniques you can get very paint-like colors, so that's not an excuse

I dont think so, I guess he selected some parts of this picture and worked on several layers and than compressed it to one picture again. There are no colors in the background and the diffrence in brightness between the car and the tree behind it are to big for a HDR IMO

Not nessesarily, it depends on what difference in stops you use how big the brightness difference is. But I think he has done some local color corrections too

Well the photo we are talking abt was entered in an online photo competition. I have seen many other photo's of this guy and it's always stunning. He used the following equipment for the BMW-shot: Canon EOS 20D / Tamron SP 28-75 f/2.8 XR DI LD

The attached photo here is also one of his artworks.....amazing

Lately I have been trying things out with my camera, when I discovered a function which is called "bracketing". Do you guys use this function to make 3 shots with different shutterspeeds? and use the resulting photo's for HDR

bracketing is an easy way to make shots that can be used for HDR. I don't exactly know how nikons work, but with canon you can preset your exposure compensation.
I have used this feature at a wedding party where the shot had to be right and difficult lighting (and a bride and groom who were wearing white and black, very, very difficult to meter correctly).
I bracketed for neutral, +1 stop, -1 stop (at shutter speed). set the camera to continous, composed the shot and focussed, held the shutter and the camera made 3 shots automaticcaly with my preset exposure correction.

So bracketing is a fast way to make 3 pictures with different exposures. It has the same effect as manual setting of exp compensation. And therefore it is perfect for HDR

And how was the result of this all? Did it work out well? Do you have some examples Erik, of HDR photo's you made yourself

I don't have any HDR pictures here, that's because i'm often too lazy to carry my tripod with me without a tripod it is almost impossible to take HDR.

I have used the bracket function sometimes when lighting is extremely difficult, like my example of black and white clothing together. Or in badly-lit ereas. I make 3 pics with different lighting and choose the best later (i can make little adjustments later, thanks to RAW shooting)

there is a very nice article on HRD on the site from traumflieger.de, if you understand the german language, there are some very interesting articles about photography on that site
