It’s common to think that most professional photographers, or all professional photographers, shoot in manual mode, for the simple reason that it offers the greatest possible control over a photo. Why would you leave your camera to make important decisions without your input? However, as valuable as manual mode is, you may not need to use it 100% of the time — even as an advanced photographer. In this article, I’ll explain semi-automatic modes and cover some cases where they can be the quickest option available, without sacrificing any control over your settings.
In this article, we will go over what exposure compensation is on a digital camera and how you can take advantage of it to make adjustments to your exposure when shooting in camera modes such as aperture priority, shutter priority, program mode and other scene modes of your camera. Every modern camera today has a built-in capability to adjust exposure settings in order to make it easier to properly expose images. In simple terms, the idea is to be able to control the brightness of an image, so that it does not end up looking too bright or too dark. To be able to do this, one has to use the Exposure Compensation feature, which is typically provided either as a dedicated button on a camera, or as a dial that one can move from positive exposure compensation to negative. Let’s take a look at how you can utilize this great feature on your camera and take a full control of your exposure.
There are many combinations of aperture, shutter speed, and ISO that will correctly expose an image. With all those combinations, which one is the right one? If you leave your camera in full program mode, your camera will pick a combination for you. However, letting your camera have complete control is not why you bought an expensive DSLR or mirrorless camera! Learning how to adjust the settings and modes on your camera before you click the shutter will give you the upper hand. You will end up capturing images creatively, rather than by chance. Read on to find out how aperture, shutter speed, and ISO affect the look and feel of a photograph and how to choose the best camera settings to take creative control of your images.
In this final installment to this series, I have chosen to discuss one of my favorite topics in photography: close-ups. My goals with this article are to provide a basic understanding of light and exposure when photographing a subject at close range, the rationale for exposure loss during magnification, and guidance on how to correct for this exposure loss. To illustrate these principles, I will share my own empiric observations, review the pertinent calculations that govern magnification and exposure loss compensation, and discuss select photographs that I have made at close range. Hopefully, this article will help beginning and advanced photographers grasp the physics of light at close range and take command and control of magnification and exposure compensation. Although I crafted this article from the framework of a photographer using traditional close-up and macro equipment (i.e., bellows, extension tubes), the use of an external light meter (i.e., non-TTL metering), and continuous lighting (e.g., natural light, lamps), the tenets and technical considerations for close-up exposure compensation are still relevant to those photographers who prefer automation, TTL metering, and electronic flash. Finally, I will wrap up the discussion by sharing some thoughts on the use of film as a tool for learning the visualization process.
