HDR Photography

What is HDR Photography?

High Dynamic Range photography or HDR photography is an advanced set of photography techniques that play on image’s dynamic range in exposures. HDR Photography allows photographers to capture a greater range of tonal detail than any camera could capture thru a single photo.
While many imaging experts regard HDR photography as the future of digital photography, the discipline has long been in existence.
HDR photography is present in many pictures taken through modern day digital cameras. The truth is, if you are a real photography enthusiast then there is a great chance that you have taken at least one photo exemplifying HDR photography.
The real functions or even executions of HDR photography may be debatable. But no matter which website or source you consult they will always say it is a technique that employs the great use of exposure range to get distinct values between light and dark areas of the image. Its real intention is to create an image that accurately characterizes the intensity levels found in natural scenes. If you ever wondered why the picture you took was different from the scenery you actually saw, then maybe it’s time for you to learn HDR photography.
HDR Photography is the technique used to capture and represent the full  DR found in a scene with high perceptual accuracy and precision. To remember things better, think of the 3S: sunlight, shadows and subjects. These are the things that make an ordinary picture an HDR image.

Theory Behind HDR photography

There are two theories behind HDR photography. And as the technology around HDR photography evolves so is the discipline itself. But if one wants to take HDR imagery seriously then he must first understand the concepts and theories that make up this discipline.
The most fundamental of all HDR photography theories is to take multiple shots at varying exposure levels of a particular subject. A special computer program will then combine the images together into a single image. This is just an incarnation of the original theory during the time when there are no digital cameras and advanced computers and programs were nothing more than a work of science-fiction.
The second theory is the one that capitalizes on the RAW processing software to create various exposure levels of the same image. Modern Digital SLR camera and a lot of the Point and Shoot models allow photographers to capture RAW images. A RAW image or file is the data captured by your Camera’s sensor that is not processed yet and therefore does have color information. You can manipulate this file, adjust its color, lighting or while balance.

How to gather data for HDR photographs

Taking the images is the first stage in HDR photography. You can use a simple point and shoot camera or a fully configurable digital SLR camera.
In both techniques you will need a camera with configurable exposure settings. All DSLRs and most point and shoot cameras have this. Certain SLR cameras have bracketing function which makes it easier for photographers to change exposure settings.
For starters, you can use the following setting: ISO 200 and Aperture Priority Mode. And as they say good things come in threes, you can take picture with three different exposure settings: EV 0, EV -2 and EV +2. You can experiment more on these but generally speaking, the more exposure versions you can have, the better your final image will be.
It is recommended to use a tripod when taking HDR photo. This is because tripod stabilizes the photo camera and you need to get the clearest image you can get since you are experimenting on exposure values. The best way to do this is to use a shutter remote or if your photo camera doesn’t have one, just make sure you press the shutter button lightly.

Post-processing

 

Post processing is the last stage in HDR photography that you can really control. This is where technical skills merge with creative sensibility. And with the introduction of advanced digital cameras and photo editing software, HDR image post-processing is made a lot easier.
However, this does not guarantee that having an excellent HDR image will be as easy as clicking the shutter button. There may be times that the three or more images you took with varying exposure values are simply not enough. With this, the only chance you are left with is to do a post-processing of the image.
Post-processing generally involves color correction, saturation, contrast and brightness and darkness adjustment and other image element manipulation. But in HDR photography we need to concentrate on contrast and brightness and darkness adjustment. Brightness and darkness adjustment is the direct digital translation of exposure manipulation in the picture taking stage. If in the camera you adjust exposure settings, in the post-processing stage you will adjust the brightness.
The main advantage of process is surpassing the limitation of actually configuring your camera in different exposure levels. While some cameras may have eight exposure settings and therefore 8 different images, post-processing can simply give you a limitless number.
After the shoot, transfer the images to your computer. There is a merge to HDR feature in many photo editing software including Adobe Photoshop and above, Photomatix Pro, Dynamic Photo HDR and others.
Post-processing software also allows you to blend photographs with different exposures. This clearly increases the dynamic range of the final output photo. There is also tone mapping which reveals highlight and shadow details in an HDR image made from multiple exposures.

Black and White Photography

Black and white photography

Funnily enough, in the age of digital SLR's and highly colored computer graphics, black and white photography seems to be re-emerging as a strong trend. Many new photographers presume that all they need to do is take the shot in black and white to start with, using the onboard monochrome camera setting. If only black and white photography was that easy. Like any style of photography, it takes practise. Otherwise, you could end up with a photo that seems flat and lifeless.

Black and White Photography Tips

 1.Shoot in RAW

I know many readers of DPS can’t shoot in RAW (because their photo camera doesn’t offer it) or don’t shoot in RAW (because they either don’t know how or don’t like to) but for the most control in the post production phase of converting your color images into black and white ones – you’ll want to shoot in RAW if your photo camera does allow it. Of course shooting in JPEG doesn’t stop you shooting in black and white – but if it’s an option, give RAW a go, you might be surprised by what it offers you in post production

 2.Low ISO

Shoot with the lowest possible ISO possible. While this is something that most of us do in color photography it is particularly important when it comes to black and white where noise created by ISO can become even more obvious. If you’re after this ‘noise’ (or grain) you can always add it later in your post production – but it’s harder to go the other way and take noise out. 

3.When to Shoot 

Many digital photographers actually prefer to shoot images for Black and White in low contrast situations. So an dark or overcast day can be a great time to shoot out door shots.
Ironically these are the days that those who shoot only in color sit at home complaining about the ‘poor light’. So next time you find yourself with a dark and gloomy day – shoot some black and white shots.

 

4.Composition 

 

Most of the general tips on how to compose or frame a good shot apply just as well to black and white photography as they do when shooting in color – however the main obvious difference is that you’re unable to use color to lead the eye into or around your shot. This means you need to train yourself to look at shapes, tones and textures in your frame as points of interest. Pay particularly attention to shadows and highlights which will become a feature of your shot

DSLR camera by Yaniv Berg

The unique DSLR photo camera concept looks really like a cylindrical smoking pipe. It’s designed by Yaniv Berg, a designer from Israel. From the unique shaped  photo camera, it’s not hard to see the photo camera is inspired by retro reflex photo camera, for instance, the horizontal LCD viewfinder on the top of the photo camera, which allows you to capture images from low angles. No doubt, the way to hold the photo camera also can help you take clear photos.
Unfortunately, the digital single lens reflex photo camera is just a design concept. We have no idea whether the DSLR  photo camera will be on the market.

Hasselblad Celebrates Centenary of Founder's Birth with Launch of Limited Edition Hasselblad 503CWD Digital Camera

In recognition of the centenary of Victor Hasselblad's birth on March 8, 2006, Hasselblad unveils the Hasselblad 503CWD Anniversary Kit, a prestigious high-end photographic system that offers state-of-the-art digital capture technology elegantly integrated with a classically designed Hasselblad 503CW body.

Combining the rugged reliability of the black and chrome V System body, with its range of high performance, central shutter-based lenses, and the technology of Hasselblad's new CFV digital back, the exclusive Hasselblad 503CWD perfectly melds the heritage of the old Hasselblad with the focus of the new Hasselblad on digital high-end photography to create a new digital workhorse. Of undoubted appeal to the Hasselblad connoisseur, the camera delivers the perfect blend of versatility and simplicity in a compact, professional tool that gives the user complete control over digital image capture and is a pleasure to operate.

Christian Poulsen, CEO of Hasselblad, comments: “Hasselblad's reputation for excellence and outstanding quality was built on the V System. Therefore the Hasselblad 503CWD – a truly professional tool that is fully compatible with the Hasselblad V system, offers great value for money, and is built to the same exacting standards that have become the signature of the Hasselblad company - is a fitting tribute to the design process that Victor Hasselblad started himself in the 1940s. Having been passionate about photography, Victor would also have loved the concept of digital photography, and in the 503CWD kit, with its stylish retro body and advanced digital capture technology offering the ideal balance of old and new
Hasselblad, he would recognize the culmination of his own work.”

The 503CWD Anniversary kit will be supplied as a limited edition of 500 cameras, each one numbered and engraved with Victor Hasselblad's signature. Reassuringly solid, the kit comprises a 503CWD body with waist-level finder, specially marked focusing screen and chrome winding lever, a Zeiss Planar CFE 2.8/80mm lens and a CFV digital back, and will be supplied with a beautifully produced book marking Victor's anniversary.

Not only does the Hasselblad 503CWD satisfy the aesthetic needs of V System fans, but it also boasts very advanced and, in some aspects, unique digital technology, such as Hasselblad Natural Color Solution, Instant Approval Architecture, and versatile storage and workflow, alongside files captured on a CCD 50% larger than a full frame 35mm DSLR.

Hasselblad Natural Color Solution

Color management solutions have in the past imposed limitations on professional digital photographers, because of the forced choice of a specific color profile to suit the job: for example, capturing various skin tones, metals, fabrics or flowers. To combat this, Hasselblad has developed the Hasselblad Natural Color Solution to be used with its FlexColor imaging software. Working with the powerful, new Hasselblad Natural Color Solution enables professional photographers to produce outstanding, reliable out-of-the-box colors, with skin tones, special product gradations, and other difficult colors accurately reproduced.

Instant Approval Architecture

Some of the potential benefits of capturing large numbers of images can be lost if the photographer cannot quickly review and select the best images to present to the client. Hasselblad's Instant Approval Architecture (IAA) assists by labelling images according to technical parameters and allowing the photographer to downgrade visually poor images, having previewed them on the clear, bright OLED viewing screen. Sorting the red, amber or green flagged images is then very quick. Audible and visible signals facilitate the selection process by giving instant feedback during a
shoot.

Three modes of operation and storage

Optimum portability and image storage are critical for the professional photographer. Hasselblad 503CWD offers a choice of the portable CF card storage, the flexible Imagebank, or the tethered operation with extended, special capture controls. With these three operating and storage options, the photographer is able to select a mode to suit the nature of the work at hand, whether in the studio or on location.

For the studio photographer, the most accurate colours and highest degree of control can be achieved by using 3F RAW (3FR), Hasselblad's raw file format, in Hasselblad's workflow software, FlexColor. The file format also includes lossless image compression, saving 33% of storage space. In tethered operation tools such as live video and overlay masking bring increased productivity to advanced set composition. The newest FlexColor version allows the photographer to manipulate color temperature and compare image details across multiple images for precise image selection. Alternatively the 3FR files can be converted directly into Adobe's raw image format DNG (Digital NeGative), which can be opened directly in Adobe PhotoShop CS2.
