HDR Photography is a method of combining multiple exposures into a single image in order to achieve a greater dynamic range in an image. If that sounded a bit complex, let’s break that down a bit more. If I take a photo, the sensor only can capture a given range from light to dark, in a normally exposed image, you may lose some detail in the darkest areas and you may lose some detail in the brightest areas. But if we can take an normal exposure, an underexposed image (to get the detail in the highlights) and an overexposed image (to get the details in the shadows) and combine them into a single image, then we can get a new image that can be the best of all three.
As part of our Photography Basics series we talked about Exposure already and this time we are going to cover the mystery of aperture. Aperture is probably the least understood setting of everything on your camera. While shutter settings are very easy to understand, to long of a shutter speed and you will get blurring, pretty simple stuff. Same with ISO, too high of ISO and you introduce digital noise. But learning how to use aperture properly can kill brain cells faster than a frat house kegger party.
MELVILLE, N.Y. (Nov. 30, 2008) – Nikon Inc. today announced the D3X, an FX-format digital SLR featuring extreme 24.5-megapixel resolution and superb low-noise capabilities, which provides professional photographers with commercial-quality image performance in a familiar and extraordinarily versatile D-SLR form factor. In conjunction with the groundbreaking Nikon FX-format D3, the D3X tops off a collection of flagship level, rugged, professional caliber digital single lens reflex cameras engineered to excel in all types of professional photographic disciplines from photojournalism and sideline sports, to commercial in-studio applications.
We are beginning a series we are going to call photography basics to help explore the basics of digital photography. While the focus is on digital photography, all of the concepts will apply whether you are shooting film or digital. In this first installment we are going to look at how to control exposure by manipulating the different settings on the camera such as ISO, Shutter, and Aperture. Upcoming installments will focus on other areas such as depth of field, motion control, and specific shooting scenarios.
Canon’s update to the wildly popular full frame EOS 5D is here, and it’s better than ever. The EOS 5D Mark II has a stunning 21.1-megapixel full-frame CMOS sensor with DIGIC 4 Image Processor, a vast ISO Range of 100-6400 (expandable to ISO L: 50, H1: 12800 and H2: 25600), plus EOS technologies like Auto Lighting Optimizer and Peripheral Illumination Correction.
We have done a number of articles with different flash heads but we have never gone into the detail of how to set them up and make them work, this results in emails that we sit and explain all the details to people. So today I am going to go through how to setup these studio flashes and connect them to your camera to get the results you want.
A big stumbling block for many new camera users is how to figure out how much depth of field a particular image will have it in given the focal length of the lens, the aperture used and the distance to the subject. Trust me on this, trying to do the algebra to figure it out is not something most people want to try to do in their heads. In this article we will cover all of the math involved and then make it real easy with an Excel spreadsheet and some links to some free applications to help you out.
A common issue some people have is getting their images to portray a sense of movement. Today we are going to look at how adjusting our shutter speed can help achieve the desired look that we want. For this simple example we will look at a ceiling fan taken at different shutter speeds so you can see how adjusting the shutter speed through an entire typical range can help you achieve the exact look you are aiming for.
One thing that seems to baffle a lot of new photographers is understanding the term “stop” as it pertains to a measurement of light. We see this word used over and over with regards to shutter speed, aperture, film speed, filters, lighting, and other ways that light is used. You may hear a phrase like “you should expose one side of face 1-2 stops under the lit side of the face and expose the background 1 stop under the main subject”. For many people that’s about like asking them to solve a complex calculus problem.
If you have ever shopped for a flash or read a review, you may have noticed a section of the spec called the guide number or GN. While this value is a measurement of power that the flash has and allows you to compare flash models, is this number useful to you at all? In this article we dig into the guide number and see how we can use this number help us dial in our flash and camera settings using some math instead of just guessing and retrying until you get what you want.
