On the Apple site there is a great feature on Richard Walch, snowboarder and professional photographer. In the article he talks about his new found love, Aperture on the Mac. For those that don’t know, Aperture is similar to Adobe Lightroom and is one of the prefered choices for professional photographers who handle, process and organise large collections of RAW shots.

Apple’s Aperture software running on a 15-inch MacBook Pro is the foundation of the mobile digital darkroom that he carries in his backback — rain, shine or snowstorm — when he goes on a shoot. Aperture’s RAW-focused workflow is particularly important to Walch, who shoots RAW at up to eight frames per second in a bid to capture his fast-moving subjects. He explains: “When I get down the mountain after a full day’s shooting, I normally have around 10 gigabytes of data. Aperture handles it so quickly and so easily”.

Because of these remote locations, and because Walch is himself a rider as well as a photographer, it’s important to travel light. Walch can fit everything he needs — cameras, lenses, laptop, supplies — into his backpack, so that he can begin importing shots into his MacBook Pro while he’s still on the mountain. He explains the advantage: “We normally break for food at some point, and I take that opportunity to import and organise my shots in Aperture. This is great for me, because I can isolate any shots I’ve missed during the morning session, and get them in the afternoon”.

By the end of the day, Walch is frequently exhausted, which is where Aperture’s backup facilities come into their own. Walch says: “During a shoot, I usually hike for many miles, often just to get a single shot, so the last thing I want to do when I get home is spend an extra two hours backing up my work.

“Aperture is smart enough to know which photos haven’t been backed up to my external drive. With one click I can start the process and Aperture does the rest. For me, it’s one less thing to worry about”. Apple have a short movie with Richard’s voiceover here.

Some photographers prefer Aperture, some Lightroom - it depends on your own workflow preference. They both have trial versions so why not download them and see which fits your own style best - it might be that missing part of your photography kit. If you have a preference let us know why…

You may have heard of HDR images before but what exactly are they and what purpose do they serve? Well let’s start with what it stands for - High Dynamic Range. Basically this is a technique that allows for a far greater dynamic range of exposures (i.e. a large range of values between light and dark areas) than normal digital imaging techniques. The intention of HDR is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to the deepest shadows.

This effect is made by blending a minimum of 3 differently exposed images together to create the ideal exposure, which is more like the human eye would see it. There are various programs such as Adobe Photoshop and Photomatix which will help you automate the process as it can be quite difficult and time consuming doing it by hand using blending layers. There is still a lot of tweaking required as every picture requires different settings to achieve the desired result, so practice makes perfect.

With the rising popularity of digital cameras and easy to use desktop software, the term ‘HDR’ is now popularly used to refer to the process of tone mapping together with bracketed exposures of normal digital images, giving the end result a high, often exaggerated dynamic range. It is necessary to use a tripod for your bracketed exposures to ensure alignment and sharpness.

Searching through the net you will find wildly differing styles of HDR use with some images looking totally unrealistic with crazy colours and toning. On the other hand there are the serious photographers who use HDR to subtley enhance their pictures to create an image more akin to how the human eye would see the scene, rather than have to rely on filters to help improve the limitations of digital cameras’ sensors.

This HDR image of a sunset over a field of haybales was generated from 3 exposures using Photomatix Pro. It was then enhanced further with various Photoshop techniques. I have kept the HDR changes to a minimum to preserve the authentic appearance. Sunset images are a great topic for HDR as they have such a wide tonal range. Try attempting to create a similar result with one exposure and you will no doubt either end up with a washed out sky with a good exposed foreground or a nice sunset but no detail in the shadow areas such as the haybales. This hdr picture can be bought as a poster or canvas print from the Fotoviva Art Store.

We found a useful independent website called Photoshop Tutorials which has a range of resources available if you are looking to improve your post processing technique. They have interesting tutorials on working with Photoshop to improve your pictures and create special effects for backgrounds, as well as showing how to create those professional looking shots that the real pros seem to make.

There is also a section on Photography skills which provides handy ideas for generating great photography before you throw it into Photoshop. In fact there is a whole wealth of information for the photographer who is looking to improve their work or find new resources. Speaking of which, head on over to the Photoshop Plugin Download area which has lots of hard to find additions to integrate into Photoshop.

They also have a new forum that is growing all the time, so if you are looking for a new place to discuss everything Photoshop sign up and start learning new skills.
