by Henry Soto·Comments Off on White Balance and Photography
White balance is a topic that doesn’t get a lot of attention
in photography. Years ago, the film purchased for your camera controlled the
white balance. You would simply purchase the film based on what you plan to
photograph and how the lighting would be. These days, the white balance is
controlled in digital photography through your camera’s settings.
The way the human eye color differs greatly from how it is
decoded by our digital devices. Even individual digital devices interpret color
differently. That can create a situation where your final images look much
different when printed. There is a way to get the correct color, though, known
as color management. To properly manage color, there are several things you
must learn to work with such as your monitor calibration, the postproduction
software you use, and your camera settings.
All forms of white have a color. Each color has a
temperature. Different temperatures of light create different hues within your
image. The Kelvin scale measures the color temperature scale of light. When
looking at the lower end of the scale, you have more reds and yellows at around
2000 to 4000 Kelvin. When you get close to 5500 Kelvin, everything becomes brighter,
sort of like the light you see on a sunny day at noon. As the Kelvin increases,
everything becomes bluer.
Every camera comes with a sensor that will determine the
color of the light. This is typically done with the AWB, or auto white balance,
setting that sets the sensor to the correct white balance on the camera. The
AWB sensor tends to be quite accurate but can be fooled when presented with a
large single color, such as a child wearing a bright red outfit. In that case,
the sensor may be fooled into seeing the image as redder than it truly is an
overcompensate by adding more blue to the image.
The white balance is generally managed through the camera
itself, it is important to understand the basics of white balance so you can
manually adjust when needed to get the pictures you desire.

Aperture is a
part of photography that many amateurs lack understanding of. It is a simple
concept, though, and one that is important if you want to grow in your
A simple way to
better understand aperture is by thinking of it as your eye pupil. As more
light comes in, the wider your pupil becomes. And exposure is produced by the
combination of ISO, shutter speed, and aperture settings. As the size of the
aperture diameter change, less or more light is allowed into the sensor. The
aperture should be determined based upon the situation you are photographing.
In general, though, the wider the aperture, the more light while the narrower
the aperture, the less light allowed into the sensor.
photographers are confused by aperture. Part of this is because of the language
surrounding aperture. Some will refer to aperture as wide or narrow, while
others refer to it as small or large. It can refer to either considering a wide
aperture is referring to the opening of the lens being wide, while a large
aperture is referring to the f-stop.
The size of the
aperture is measured using the f-stop scale. The f-number refers to how wide
the aperture is open. The size of that opening will affect the depth of field
and the exposure in the final product. It is important to remember that the
lower the f-stop, the wider the aperture is open. If the aperture settings on
your camera are set to a small f-stop number, your aperture is wide open. When
you have a higher f-stop, your aperture is narrow.
numbers can be difficult to understand fully, but to help you better understand
them, remember that as the numbers rise, the settings on aperture decrease to
half its size. In other words, each f-stop will allow 50% less or more light
through your lens.
Aperture can be
a difficult topic to learn, making it even more important get out and practice
your photography at different f-stops to see what happens.
by Henry Soto·Comments Off on Improving Photography with Shutter Speed
This week, we will be discussing one of the most obvious
factors that contribute to exposure, the shutter speed. Shutter speed tends to
have a huge effect on your photos. When you don’t know how to use shutter speed
correctly, you tend to have photos that are blurred. Continue reading below for
a better idea on how to use shutter speed for your photos, whether you want
sharp photos or prefer something more artistic.
First, we will discuss what shutter speed is. To summarize,
shutter speed is the precise amount of time your camera will use to record an
image. The camera’s shutter is how this is done. When the shutter opens, it
allows light to hit the digital sensor or film plane.
Generally speaking, you will have camera shake if the
shutter speed value is shorter than the focal length of your lens. For example,
you will want at least 1/60 of a second for a 50 mm lens. You will need a
tripod if you attempt anything slower. Another option is to have image
stabilization on your camera.
Most times, it is best to snap your photo quickly, around
1/1000 of a second preferably. At this speed, the movement of the object will
be frozen. Of course, you must take into consideration the speed your subject
is moving and how far you are from your subject. For the most part, though, you
will have blurred images if you use a slow shutter speed.
Just like aperture, stops are used in photography in
relation to shutter speed. It seems to be an easier concept to learn, though.
For example, understanding the concept of using half of an exposure in relation
to shutter speed is simpler than understanding that same concept with aperture.
You simply must remember that a full step down doubles the amount of light and
a full step up will half it.
Once you understand the basics of shutter speed, you will be
able to enjoy sharp images through your photography.
by Henry Soto·Comments Off on ISO Light Sensitivity
In our last article, we discussed the importance of learning
exposure. Once you learn the basics of exposure, it’s time to begin learning
other parts of the camera such as the ISO.
It is unknown exactly what ISO, but it is a very important
part of manual photography. The ISO of the camera determines the light
sensitivity. In order to use it effectively, you must determine how much light
you need, then set the digital sensors to that sensitivity. For example, if
your photography set up has plenty of light, you may choose to set your camera
to an ISO of 100, which is the lowest setting. If you are in a dark
surrounding, such as outside in the middle of the night, you will need to set
your ISO much higher. Many cameras will allow you to set your ISO as high as
6400. That does require you to make a sacrifice, though. When you have your ISO
set high, you will find a lot more noise in your finished product. That is
simply because the camera is compensating for the low amount of light in your
Some of the newer, more expensive cameras may have less
grain with a high ISO, though. Those cameras’ have an improved ability to pick
up light in a dark scene, making the overall picture look much better.
One of the best ways to learn about your cameras ISO
abilities is to play around with it. Try different settings in the middle of
the day and late at night. Also try different ISO settings at other times
throughout the day. Look at the final product to determine what settings are
best on your camera for each scene. Once you play around with it enough, you
will understand the role that ISO plays in your photography.
If you would like more information and hands on learning
when it comes to ISO settings, be sure to come to our next meeting. We would
love to have you.

Here at Flat Irons Photo Club, encourage our members to pick
up their cameras regularly, even if they don’t understand the functions of the
camera. Once you get a better feel for your camera, though, it is good to start
learning the different basics. That is where these articles come in, to help
you learn more about your camera and how to use it.
If you have just started photography, you may have a basic
camera that you are unable to modify much. If you are more serious, though, you
likely have a DSLR camera where you can adjust ISO, shutter speed, aperture,
and more. If so, we are here to help you get started learning how to use those
The first function we will be exploring is exposure.
Exposure is basically the brightness or darkness of a photo. Getting a properly
exposed photo may seem easy, but it isn’t always as simple as it seems for
beginning photographers. Luckily, until you learn how to adjust exposure
yourself, your camera will control that function under the automatic selection.
Though photographing on auto can be useful, it tends to limit your control and
There are times when you may want to purposefully create a
darker photo, depending on your desired effect. A darker photo tends to bring
along with it a darker mood. It can also bring out more color in your photo.
For example, if you are photographing a colorful sunset, creatively darkening
the exposure can help bring out the colors. Though the photo is not technically
correct in its exposure, if it portrays the mood you are looking for, then the
photo is a success. Just keeping your camera on the auto selection, it will
always choose the middle ground between light and dark exposure, losing the
Now that you understand the importance of learning exposure,
you may be interested in learning more about how to get the effects you are
looking for. If so, join us at our next club meeting. We will go over the
basics of exposure and give you some practice using what you learn.
