Most of the digital cameras are so advanced that makes people wonder why do they need a photographer when they can take nice photos by on their own. Hiring a photographer isn't just about carrying a heavy DSLR with expensive lens on it walking around taking photos. It is about getting creative images that stand out from the rest and using the correct camera setting for it. Sure enough, putting any camera in auto mode and you are ready to shoot for any events and even weddings. But does that make the person a photographer? We will talk about a few main points that a photographer sees before taking a photo. Environment An experienced photographer will know the different kinds of lightings in any environment. Regardless of fluorescent or incandescent lightings, it will affect the image a lot. We call this white balance. What it does is to balance the color temperature and show “white” as white. It is a way of measuring the quality of the light source based on warmness or coolness measured in Kelvin. Which is why on most DSLRs you will see the white balance measured with a set of numbers followed by (K). A wrong white balance setting can cause a white object to look yellowish or bluish in the photos. Flash Not all photographers use flash nor all events require using flash. It all depends on the lighting conditions and the type of camera the photographer using at the point of time. Lighting will differ from venue to venue and events going on indoor and outdoor simultaneously. So photographers are geared to tackle these kinds of lighting issues at all times. Why we mentioned about the types of camera is because technology in photography is so advanced now that the camera can shoot in a dark condition even our human eyes can't see properly. Therefore, flash is subjective when using such good camera. Aperture, Shutter and ISO Here comes a more complicated part of being a photographer. But once you understand the concept, you are able take control of your exposure and ditch auto mode for good. There is a lot of confusion going on when you first come in contact with exposure triangle, we will try to explain it as simple as possible. Let’s go… Aperture is to control your depth of field, the focus area, measured in f-stops. Usually you hear photographers saying F2.8, F4 etc. and even on the lens itself, this is to set the area that you want it to be in focus. The smaller the number the smaller the focus area is. For example, if you want to take a photo with just your subject in focus and background out of focus, you will likely to use F4 or lesser to achieve it. Or if you are taking a group photo of your family members, you will likely to use F8 or larger to make sure everyone in the photo is in focus. Shutter speed will depend on the movement or the activity of the subject you taking photograph, measured in 1/number to seconds. The numbers at the back represent the opening speed of the shutter of your camera. A slow shutter speed (e.g. 1/10) will cause your image to be blurred because the shutter opening is too long for sensor to capture a sharp photo. It is useful of you are taking a non-moving object or you want to capture a silky smooth waterfall. A fast shutter speed (e.g. 1/160) will stop the movement. For example, a sports event and you want to freeze a runner in action. You will need shutter speed of 1/1000 or faster. ISO is the sensitivity of the camera sensor and it varies from camera to camera on the performance. Some camera is able to perform up to ISO 25600 while some topped at ISO 12800. ISO will affect the noise in your images and the term noise technically means the amount of gains in the pictures. A higher ISO will make your camera sensor more sensitive to light and introduce more gain in the photo. Ideally, you would want your ISO settings to be as low as possible. On the right is an example of how aperture, shutter speed and ISO function. After knowing each function, we now put these 3 together to create an exposure for an image. Sometimes by looking at the camera settings without looking at the picture, you can tell how is the lighting condition on the actual environment. For example, in manual mode, we have settings like let’s say F8, 1/125 and ISO 6400. The lighting condition for these setting can be very dark and maybe the photographer is trying to take a group photo. Usually in any scenarios, the photographers get to decide which two settings are more important compared to another. For example, we want our image to be out of focus and less grainy image. We will need the setting to be somewhere F2.8, ISO 100 and let the shutter speed compensate for the overall exposure.
These are the brief fundamentals on the exposure triangle. Knowing which area is more important compared to another and let the third exposure element to compensate the rest. Let us know if you have any questions with regards to this week’s topic by contacting us here.
