Banff National Park Alberta, Canon 5D Markii, 24-105 at 24mm, f16, 1/25sec, ISO 200, HDR 3 exposures, Photomatix 5.0 |
First
step before starting with HDR, get a tripod, and a cable release
• WB White Balance to daylight ( WB can be
change with most editing programs, but to get the same color temperature for
all your exposures when shooting for HDR, you have to get the same WB for all
of them, you can use any WB setting except auto WB.
• Set your camera to AV "Aperture
Priority" or Manual,
• Set your Auto Exposure Bracketing (AEB) for
the number of exposures you want, most camera will let you take 3, -1, 0
+1, or -2,0,+2, depending on scene nothing stop you to try both, if you have a
more advance camera, you can try different setting up to 9 exposures,
• Set ISO not
higher than 200, to prevent noise in the shadows
• Set your camera on Continuous Shooting
• Shoot in RAW
• Set Auto focusing to get the subject in focus and turn off your
auto focus button before shooting HDR, to insure that the focus will not change
during the HDR shooting.

• High-dynamic-range
photographs are generally achieved by capturing multiple standard
photographs, using exposure bracketing, and then merging them
into an HDR image from 3 and up to 9 exposures,
depending of the scene and your camera limitation, I am a Canon user and did HDR
for many years using only 3 exposures, most camera have this ability, now that
I upgraded to 5D Markiii, I am setting my HDR to 5,
it's more than enough for me.
• Any
camera that allows manual over- or under-exposure of a photo can be used to
create HDR images. The best cameras for the job are the one with an auto
exposure bracketing (AEB) feature.
• One
thing that you have to understand is
that many scenes don't need HDR, low contrast scenes are fine with most of camera
dynamic range, but you can always use bracketing to get the best exposure,
by using your camera auto exposure bracketing (AEB), I set mine at -1, 0
+1, this range is more than enough to get the perfect exposure. It's also ok to have pure black in an image, you don't need to have detail in every shadows or highlights, think about silhouettes image, where is no detail in the shadows, or for some moody image where most of the image is dark. In the old time before the digital era, most photographers make sure their highlights we not overexposed to prevent the lost of detail, lost detail in highlights couldn't be recovered, contrary to lost detail in shadows that could, same story with digital, even with the best program the ability to bring lost detail in highlights is very difficult almost impossible, a different story with detail in shadows that can be retrieved with most program, especially if you shoot raw file.

The best way to ensure that you are keeping the detail
in the highlights is to expose for them and retrieved the lost detail in
shadows with your program, you may end up with grain in the shadows but you'll
get quite a bit of details back. To prevent grain problem the best way when you
have high contrast scenes it to use your AEB, and used HDR program or manual
HDR whatever work best for you. To learn

post from School Of Digital Photography

• When I am facing a high contrast situation, where
I cannot exposed for the shadows without overexposing the highlights, I set my
camera to AEB 5 exposures and shoot, knowing that I can work with 5 files to
bring back details.
• Our eyes are very adaptive and they are also
more sensitive to intensity than color. It is estimated that our eye can see
over a dynamic range of nearly 24 f-stops while a digital camera can capture a
dynamic range around 6 to 11 f-stops at best.
• This means that when we look at a beautiful scene with a high range of lights we see much more detail. We can see detail in the shadows as well as clouds in the sky. But for camera to correctly capture the scene with its limited dynamic range is far more difficult. We (or the camera auto metering) can overexposed the image to get detail in the shadows or underexposed the image to get detail in the bright sky but can't get both the same way our eye can.

• The
good news is that with all the tools we have in the digital world, the
quality we can achieve is very good even with small DSLR, and e some
point and shoot, just make sure that you have the AEB option, even if it
is just for the basic 3 exposures bracketing,
• Shooting
indoor exposure problem with lights coming in from windows, skylights, and
doors; over exposing the highlights and under exposing the shadows! Using HDR
will solve this problem, it's been use a lot in real estate.

Banff Town Main Street, 5D Markii, 24-105 at 28mm, f4, 1/50 sec, ISO 200, 3 exposures, NikHDR Efex Pro, for this one I didn't want a realistic look, I wanted a bit of grunge. |
• I
am using all of the above programs, but I also like to do manual hdr, to get a
natural look and control over my image. Depending of what you want to achieve, natural, artistic, painterly, grunge, color or black and white, the choice is yours. On advantage of shooting using AEB 3 to 5 exposures is that not only you can use the files to produce HDR, but also getting the perfect exposure each time. If you want to do a manual HDR you can keep it really sample as per the following post by Post Processing Mastery using only 2 exposures.

As you can see on my examples, natural or futurist HDR is a question of taste, you do what you like, and experiment with it, have fun! As a finishing touch when working on HDR I used onOne Perfect Effect 8 software in combo with Photoshop.
