HDR Photo questions

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

HDR Photo questions

Postby larsonpics on Tue Feb 24, 2009 12:06 pm

I'm brand new to the forum and just trying to get my feet wet. All I can say is what a great resource. So be easy on me if I don't have a lay of the room, yet.

I have just started playing around with HDR photography. I have recently purchased Photomatix and have taken some bracketed photos. A couple of questions about HDR. What is the recommended number of photos I should use for an HDR photo? How do I recognize good subjects for HDR photography. Also, Here is a recent HDR photo I took that was comprised of 5 photos with +1 EV for my exposure compensation. I would appreciate any tips or suggestions.

Hi there. Welcome to the forum.

I have also played with HDR images and one thing that I have noticed with Photomatix is that it is easy to overdo the HDR. When you do you get that cloud or smokey look that you have in the sky on your pier image.

I prefer to reduce the amount of HDR I apply to the image to create a more realistic contrast, one that the eyes can see plus just a touch more.

I also try to use as fine a difference in exposure as possible, which means I end up with about +/- 0.3 per shot. I do end up with a lot of images to process though, which can be a pain. Having a camera capable of a high rate of exposures (8FPS) helps tremendously with moving objects such as waves. (Except when it's dark and long exposures are necessary.)

Try to give the software as much help as possible and it will produce a much nicer result. Here is one image I applied this principle to, just as an example of what I do with HDRs;

The best thing to do is experiment until you are happy with a style of HDR that suits your photography. Some people prefer images that defy the principles of light while others, me included, find that simulating light conditions gives a nice look.
