Know Histogram In Photography | Tutorial Photography
Know Histogram In Photography – you may have asked when the exploring the camera or are reviewing your shots and find a screen labeled ‘Histogram’. Are Histogram and why should I pay attention? Is there an ideal shape of the histogram graph? What is the purpose of the histogram?
What is a Histogram
We should at least take the time to discuss this topic histogram. We’ll review a little bit about the overview and answer the questions above. Histogram is a very useful tool to help a lot of camera owners to take a short summary or conclusion of any photograph their tonal range. Histogram Chart describing tone in your image, from black (left side) to white (right side). The higher the graph at any point then the tone is more pixels in the image, so a histogram graph that has a lot of dark pixels will tend to cone to the left, and vice versa images that have a lighter tone is likely to be high on the right side.
Histogram advantage is that even with a small LCD screen on the camera, you can check or review the results of your photos, and make changes to the camera settings when the histogram gives the information that the image is too dark or bright. As we know that the relatively small size of the camera’s LCD to see the results of our photos, and we often come home and find the image underexposure or overexposure when looking back on the computer screen that is larger than the camera’s LCD.
Some examples Histogram
Let’s look at some examples of histograms and review the following:
Photos of Flowers has the right exposure, as shown in the graph of brightness from left to right
In this second crop photos not appear to have the right exposure, the graphics are great differences on the right side of the histogram. Most of the photos looked dark and underexpose
In the third flower picture, looks really over-exposure and the ‘washed-out’. It can be seen from the right side of the histogram of the towering, this means the area filled with white light instead of highlight detail
Is There Ideal of Graph Histogram?
As in most aspects that exist in the world of photography, beauty is in the eye of the beholder and there is always an element of personal taste and a different way to express yourself as a photographer. Nothing in this world called Histogram ‘Perfect’, as well as the subject of a different type of photography will give different results. For example, when taking photos silhouette will give a histogram graph with peaks at both ends of the spectrum, and there is not much in the middle graph.
In general, indeed we would always want the photo with a balanced tonal range and spread. The images have the correct exposure will typically have a peak in the middle and taper toward the edge of the graph.
current digital camera has many features that come with the LCD screen brightness settings, to look back at the photos that have been taken. Increases the brightness or look at the screen with a brightness that is too high may result in exposure evaluation errors. A histogram is a better way if you are skeptical of the images when evaluated through the LCD screen on a digital camera.
Did you Know?
Digital Photo Editor like Photoshop, Lightroom has a feature similar to the existing histogram on a digital camera to read the brightness of an image.
