    Default Hdr

    I think I'm gonna try a shot at HDR this weekend.... I haven't done any deep research as to the technique aside but will before I attempt....

    All I know so far is that I take that same shot at multiple exposure settings and I guess kinda stitch them from there using a software program...

    I am looking for any advice as to what not to do(mistakes that you made when you first tried)... and are there subjects that suit HDR more than others? ie landscapes vs portrait or macro...?

    I am not much of a HDR expert, but I guess the classic subject for a HDR image would be sunrise/sunset.

    HDR is only really useful if the dynamic range of the image can't be captured in a single exposure.

    So, the typical successful HDR images are landscapes (with a large tonal difference between the sky and ground), interior images (churches are good candidates, where you get a range between the bright stained-glass and the darker interior areas), night-time cityscapes (lots of range between the bright lights from buildings/cars and the darker areas).

    True (multi-image) HDR portraits are pretty much impossible since people would move between shots, though you could alway composite an HDR background with the person. Not to mention that the increased contrast of HDR is very unflattering to the skin tones.

    If you like the re-contrasted look of HDR images, but you have just a single image that already has the full range, you can still use HDR processing on it, but you can pretty much get an identical result using the Shadows and Highlights tool in Photoshop, or anything other processing that increases local contrast (link to a PS action I made that does the same thing with layers).

    I would also add that HDR is only ONE method of getting detail and tone and even the HDR\illustration look does not fit all landscapes.

    A neutral grad filter on the camera will often do the same thing and yet give a more natural look to the photo as a bonus. The dynamic range optimizer or variations thereof on individual cameras will also produce greater detail in shadow and highlight areas.

    Increasing contrast by the way, reduces the tonal gradation and the detail in the darker tones, so that is not be recommended either in colour or black and white. It also washes out the brighter tones.

    Thank you everyone.....

    I know that HDR is kinda overdone but wanted to give it a try for learning purposes....

    It rained all weekend here and I was not afforded any decent landscapes shots to try... maybe next weekend...

    HDR, though, just increases *local* contrast, so it does the opposite.

    Sorry, I did not mean to suggest that HDR is not to be recommended but rather the general notion of increasing contrast.

    Pardon me for butting in here, but I was reading over all the posts and didn’t see where anyone had followed up with any HDR images. I’m a big fan of HDR and have made several attempts at it myself. Most of the time, the shots I make could easily be made with the proper exposure without having to resort to the processes involved in HDR photography. It’s just that I like the tone mapping options available in some of the software used to merge the images.

    Here’s one shot at night of a bridge not far from my home. It was done this past summer and I’m sorry I don’t remember just how many frames I used to create the image. It was at least three, and maybe as many as five or six.

    Hey Travis ... did you listen to Podcast #59 - HDR with Joseph Cartright - http://www.photography.ca/blog/?p=198 ?

    If you are going to try to use the HDR Software for the first time you might want to have a listen to this one. Understanding the visible ranges within the image you create is necessary because the HDR rendered image tends to look like crap at first until you know what to do with it.

    I don't. Haven't looked into it myself yet. I tried once but it looked like crap so I went back my own method of manually blending the exposures via layers and masking etc. After listening to that podcast I now realise that I need to know more about HDR softeware if I'm going to use it. Either that or stubbornly keep using my own way.
