What is High Dynamic Range Imaging? (HDR)
HDR is when you take 3-5 or 7 photos at different exposure settings, and then merge them into a single image using speciality software. What you get are beautiful photos with incredible detail, controlled lighting and accurate colour. You cannot reproduce an HDR image manipulating a single JPG or RAW image in Photoshop.
This might be a good time to turn your cameras towards the night sky, with Jupiter, Venus and the moon converging on one another.
Here’s a photo I took of a previous convergence, or conjunction as I believe the phenomenon is also known.

The brightest planets in the solar system are lining up in the evening sky, and you can see the formation—some of it at least—tonight.
No text on this page, just a collection of excellent photographs, many of them iconic ones that you will recognise.
Calibrating our monitors and printers is something that we, as photographers, should be particularly concerned with. Lifehacker recently made a blog post that talks about this, covering some of the options available.
On her blog, our member Noleen has posted about Stephan Cooper, accomplished car photographer. There are a number of photographs covering motor racing as well as some more personal work in the form of landscapes and portraits. She begins,
Famed photographer and author Scott Kelby listed Stephan Cooper as one of “The Best five photographers you might not have heard of” I am proud to say I can call this photographer a friend.
Chris, one of our members, sent me this link to a beautiful time lapse video of the Milky Way. The picture about is a grab of one frame and gives some idea of what the video is like.
Terje Sorgjerd, the photographer behind the viral video The Aurora, has done it again. Here, Sogjerd captures the Milky Way over El Teide, Spain’s highest mountain. Click through to watch, and get details on how the video was made.
Filmed between April 4 and April 11, 2011, the individual frames were shot using a Canon 5D Mark II with a Canon 17mm TSE, Canon 16-35mm II, Canon 24/1.4II, and Sigma 12-24mm.
Florian, one of our members, sent in this article that he thought others might find interesting. It begins,
For years, lens makers have fought hard to market lenses of wider and wider aperture. Wide apertures (e.g., f /1.4 instead of f /2) but a series of measurement published on dxomark.com cast some doubts on the real benefits, for digitally equipped photographers, of these progresses.

When you start to get serious about photography, something becomes very apparent to you – that getting different effects while photographing the same subject doesn’t need to be particularly difficult. It is actually quite easy to render totally different effects on a single subject using a few tried and tested tactics. What you will come to realise is the variety of outcomes that can come from that single object is quite remarkable.

Employing long exposure photography techniques is a great way to create an image that makes others go “Wow!”. If you’re unfamiliar with long exposure photography the major ingredient needed is low light conditions, which will require your camera to expose for longer periods of time. In fact it’s even possible to use filters to reduce the amount of light that comes through your lens so as to produce long exposures even during the brightest times of day. Long exposures enable photographers to create an abstracted or surreal visual experience as opposed to reproducing a scene as we might see with our naked eye. In this regard long exposures allow you to artistically create something from a subject or scene that might otherwise seem ordinary with more standard photographic techniques.

Until a few years ago, workflow was a virtually unheard of word. Now it is the mantra of nearly every professional photographer but what does it mean? Well, put simply, its carrying out the day to day work tasks in a consistent and hence efficient way. Following on from my last article on Digital Image Management I want to talk about my workflow for ingesting and organizing images.
