My Photos Aren't Sharp
(Part 2)
By: Jason Busch
This is the second part of My Photos Aren't Sharp.
You may have thought there was only one page of
possibilities for unsharp photos, but there are
more.
Environmental Conditions
I
took a roadtrip with some friends to Las Vegas back
in 2002, in February. We traveled through parts of
Oregon, California, Nevada, Utah, and Idaho. Seeing
this country during the months just before spring is
absolutely the way to go. Everything is clear,
crisp, but of course, the temperatures are very
cool.
One of the obstacles in taking a few particular
shots, was the wind factor. Regardless of trying to
take images handheld in between bursts of wind, I
noticed when I got home to review the images, they
were not as sharp as I had thought they were. My
images looked like I was taking shots from a moving
car. Wind is one of nature's elements which can
become a pain to deal with if you are not aware of
it or think you can manage it on your own. A tripod
definitely helps.
Rain is another obstacle. Most of you may not have
to deal with it as much as those who are
photojournalists ("PJs") or who just like to live
life on the wild side, but if you do shoot in the
rain, you will need to have knowledge of the
Shooting Trinity: Aperture, Shutter Speed, and Depth
Of Field. Sometimes you may get visible rain drops
in your image when you don't want them, and
sometimes you may want them when you don't have them
in your image. In addition, a nice little rain drop
may decide to take a rest right on the front element
of your lens, which can distort an image at
particular settings. The amount of rain is also
something to think about. Be sure to monitor the
rain and its behavior when you're shooting in it. It
can change drastically, and render an image that
would have been just a 15 seconds ago, useless.
Wind and rain can also be a great addition to your
creativity and expression of images, so they are not
necessarily unwelcome. Shoot with nature. Not
against it.
Quality
Of Your Tripod
Not all tripods are built the same. Yes, this is
true to some extent. However, you can still find a
tripod for around $50-$200 that will perform just as
well as a $500...and even a $3,000 tripod. Some
people don't want to admit this, but hey, it's their
money--not mine. In any case, regardless of the
money spent on your tripod, make sure the tripod can
accept the weight of your camera and lenses on it.
Observe if the tripod is having difficulty remaining
still when a gust of wind whips up. Depending on
your equipment, you may need a tripod that can
handle heavier equipment.
You And Your Tripod
This is sort of like the above, but looking at it
from a different angle. Be aware of your stance when
using a tripod and your camera equipment. I've seen
photographers bump their tripods when shooting,
accidentally trip over their tripods (I've done this
a few times myself). Don't lean into the tripod.
Extend yourself OUT to the tripod, and begin
shooting. If you just have to have the tripod in
your face, read the following...
You And Your Feet
Suffice it to say, make sure your feet are firmly
planted when you shoot. Handheld or with a tripod.
The system is only as strong as its weakest link,
and yes, photographers themselves are usually the
weakest link. Be aware of what you do when you
shoot. I've noticed in some cases I actually sway
back and forth if I am stationary for a particular
time. What I do is gather myself again, and create a
new stance. Some photographers have the physical
capabilities of having the movement of a stone, and
some have the behaviors of a long blade of grass,
just waiting to be swayed back and forth.
The
Camera Diopter
Most DSLRs have a built-in diopter to match your
eyesight requirements. Also, you can buy attachments
which have more of a precise and accomodation to
your particular eyesight needs. Be sure to adjust
the diopter on your camera, regardless if you think
you need it or not. You might be surprised.
Your Eyesight
Yes, I had to mention it. If your eyesight is not
particularly accurate, this could be a problem for
your images appearing blurred. Be aware of
Presbyopia, where one eye could be more affected
than the other. This condition is progressive, and
you may need adjustments every year. Eyesight issues
are generally progressive in nature which could be
the explanation for your images looking fine one
season, and this season they are just as good as
they could be. So, be sure to have your eyesight
prescriptions up to date.
Final Thoughts
We've covered several possibilities for your images
not coming out the way you are wanting them to.
Overall, if you haven't noticed, the key to
eliminating a lot of these possibilities, is being
aware of your own behavior, and aware of your
equipment. In another articles, we will discuss
image processing to reduce (or even eliminate) the
effects of unsharp images.
