PHOTOGRAPHY BRACKETING: WHAT IS IT AND HOW IS IT USED?
Speaking of words and strange concepts in photography, I'm sure you've ever encountered this word: " Bracketing or Bracketing " while browsing through an article or tutorial related to photography. I do not know if at that time you have felt the slightest curiosity about this concept or simply turned the page like the one who does not want the thing ... Or you got to it but you completely forgot it. Whatever your situation, if you need to refresh the concept or clarify it, or just find out again, this article is for you.
BRACKETING OR BRACKETING WHAT IS IT?
Bracketing is nothing more than taking several photographs of identical composition and framing, but varying a parameter , which can be exposure, focus, white balance, flash or ISO.
WHAT IS IT FOR?
When we are not able (rather our team) to accurately capture all the correct exposure, focus or white balance settings, we take several shots by slightly varying the parameter that we are interested in adjusting.
The most common is the exhibition for those high contrast scenes (with a lot of light difference between lights and shadows) in which we often have to "sacrifice" the lights or the shadows.
Through bracketing, you will have several shots of the same scene with different values. From these shots, you can:
Choose the one that most closely resembles the results you expected.
Join the images to “add” the information through a specific-specialized software and thus obtain a more “complete” image with correct values ??in each area of ??the image.
TYPES OF BRACKETING OR BRACKETING
As I said before, the best known is the exhibition, and it is also the one we refer to most of the times we find it written out there. In SLR cameras, access is usually possible using an external BKT (Bracketing) button or within the menu. If you don't have the option, remember that you can always do it manually by varying the different parameters.
BRACKETING OR EXPOSURE BRACKETING
Many cameras have an automatic system that allows several simultaneous photographs to be taken at different exposure values. Normally the camera takes a shot with the exposure value "correct" (which is not so much because of the difficulty of the scene), another slightly underexposed, and another slightly overexposed; In total three images.
If you do not have this configuration, you must make these adjustments "by hand", yes, for this type of technique you will need, or at least it is highly recommended, a tripod to not vary the framing of the scene. If you do not want to vary the depth of field, you should adjust the speed of the scene and not the diaphragm.
Applications: For the already well-known HDR (High Dynamic Range) that has as many lovers as detractors but at least once, you have to try ;-). This article will solve all your doubts about it, by using a very simple program: Photomatix Pro .
BRACKETING OR FOCUS BRACKETING
When you need to increase the depth of field but through the usual techniques you cannot (modifying the diaphragm), you can also resort to focus bracketing . With the same idea as the exposure, through different shots with the focus on different areas of the image, you can substantially increase the depth of field of your image by joining them later with an editing program such as Photoshop or Helicon Remote .
Applications: If until now you didn't follow me too much, now you will. It is mostly used for macro photography . You have in mind those scenes of small insects or petals or enlarged objects at impossible scales, right? Do you remember the limited focus area of ??the image? Well, it is not for pleasure, it is something very associated with this type of photography.
BRACKETING OR FLASH BRACKETING
In combination with natural light , not only based on the flash, but this as a fill flash , it is about adjusting it with different power values ??to obtain the best possible result.
BRACKETING OR WHITE BALANCE BRACKETING
If you shoot in RAW, you can move on to the next point since you can do it in the post-processing process just by moving. If not, keep reading. It is about taking different shots by varying in each of them the chosen white balance . For what? Because many times it is difficult to see at the time of taking the picture which white balance is better at that time . It is best to try a couple of logical options (if you are under a fluorescent it does not make much sense that you use the daylight, for example ) to get the best result. As you can see, bracketing is not only for itself to unify the different images through specific software, but sometimes it is based on, through several "tests",be able to choose the most correct values ??for each occasion .
ISO BRACKETING OR BRACKETING
When you need to maintain the speed and aperture exposure values, you can vary the ISO values, taking into account that the image noise will vary from one ISO setting to another. Although if the difference is a few steps, it will be almost negligible, you should take it into account especially when working with high ISO (More ISO more noise).
Do you see how those (terrible-strange-unpronounceable-impossible-to-retain) words that occasionally appear in the arduous path of the amateur-self-taught photographer are really nothing? As long as you understand the concepts, you can call it bracketing, bracketing, or “ I take a few equal pictures by varying only one of the parameters of the shot depending on whether what I need is a more accurate exposure of all parts of the scene, or more focus ... »
In short, do not be intimidated, a few words are nothing compared to your desire to learn. So you can put bracketing, white balances, diaphragms, hyperfocal distances or whatever. Together we will discover the simplest explanation of each of them
