The waveform is video’s answer to the histogram. Like a histogram it shows the brightness levels throughout your image. Also like the histogram, it can be confusing to those new to video or colour correction. While the information displayed is essentially the same, how it displays it is very differently.
This video from Aputure walks you step by step through what exactly the waveform is and how to interpret it. Once you learn how it works, it lets you quickly and easily see under or overexposure as well as colour or white balance issues. And when you are used to it, you won’t want to shoot or edit without it.
Histograms are handy things. They either confirm that you’ve nailed your exposure or let you instantly see if you need to adjust. But, they can be difficult for newer photographers to understand.
The histogram is based around a fairly simple principle, but one that many still struggle to get to grips with. Put simply, it’s a graph showing the relative proportion of brightness levels throughout your image.
Histograms have become an invaluable tool when assessing exposure. Combined with the ability to pick at a photo you just took, they have replaced the use of a light meter for many photographers. This is true for video as well as stills.
Photographer and videographer Cédric Hauteville started a new web series and his first episode deals with Histograms For Video. He covers the obvious like what a histogram is and how to use it, but also some more advanced topics like the importance of looking at a histogram along with the photo, and how to use histograms to judge the white balance settings.
Are you just starting out with photography? Have you ever wondered why that expensive, brand new, professional grade DSLR in your hands is betraying you and not giving you perfectly exposed photos – every time?
Read this article and you can learn the secret to correct exposure with any DSLR camera – revealed for the very first time – right here on the internet.
(Warning – the truth about getting correct exposures from your DSLR camera may shock some readers – discretion is advised.)
There’s no denying the fact Tom Mangelsen is a master when it comes to nature photography. Even the briefest look at his portfolio instills a level of trust in the photographer’s ability to create great photos over and over again. Which is precisely why we tend to listen, intently, when we’re presented with the opportunity to learn a thing or two from Mangelsen. [Read more…]
Looking on the back of the camera to see if you got a shot properly exposed can be misleading. The LCD may not be calibrated showing a too dark or a too light image. Or the sun hitting the LCD can be laying tricks on you.
Yet there is a tool, that is often ignored that can give you a very quick and good indication if you exposed correctly – The Histogram.
In a nut shell, the histogram is a graph that show how many pixels of each brightness level are present in a frame. John Greengo of CreativeLive give a full back to basics course on photography, in this installation he discusses the Histogram in very easy to understand manner.
Generally, John mentions that you would want a histogram that looks like a mountain with a strong peak in the middle and a slope that goes out to either end. While specific captures may be unique, (such a capturing snow, or night shots), a strong peak on the right may indicate an over exposed image, while a strong peak on the left may indicate an under exposed image.
