Understanding How To Use Contrast In Photography

Monday, August 23rd, 2010

When learning photography, you’ll discover there are lots of different elements that make an photograph appear the way it does. Exposure, film speed, camera quality, type of frame (like a gallery picture frame) and printing method all have an impact on the quality of your final print. Contrast is one of the easist elements to manipulate in photography and also one of the most important. When used properly, contrast can take your pictures to a whole new level.

Contrast is simply the difference between the darks and light in your photographs. In terms of black and white photography, high contrast images have very bright whites and incredibly dark blacks with little room in between, while low contrast images will have more grey and appear less distinct. In color photographs, contrast can be used to describe the intensity of the colors and how they stand out in relation to each other. While theres no perfect level of contrast, a good rule of thumb is to try and create images that have pure black, pure white, and every shade in between. However, this is more challenging than it sounds!

Different Degrees of Contrast
As a photographer, you’ll have a preference on the amount of contrast that you like in your prints. Some prefer high contrast, some prefer low, but remember that its all about what works for you. As long as your pictures tell the story you want to share, there is no right or wrong answer.

If you want to see some examples of excellent normal contrast just look at the work by Ansel Adams. His landscape black and white pictures are so powerful because they cover every possible shade of grey, black and white. No wonder Ansel Adams images are so frequently seen framed in simple black picture frames in homes and offices - as the contrast black and white tones are exquisite. For an example of high-contrast, recent films such as Sin City and The Spirit used high-contrast imagery to augment their story.

Adjusting Contrast
There are a few things you can do to adjust the contrast of your images. Different types of film or digital camera settings will give your pictures different amounts of contrast. For example, slide film has a high contrast ratio compared to regular film. You can also push your film while developing it by allowing it to soak in the developer longer than recommended the longer it sits, the higher your contrast will be. Be careful that you don’t over-develop your film because, unlike prints, it can’t be redone once you develop it.

In the darkroom, you can apply a filter to your enlarger to change the contrast of your images. A #1 filter wil be a slight contrast increase, whereas a #4 filter will significantly increase the contrast level in your print. If you’re using a digital camera, most photo editing software has a built in contrast option that will let you mimic the changes you could make in the darkroom. Contrast is unlimited in what you can do with it so play around and take it to the limit and see what happens.

Contrast can control the focal point of an image, as in where your viewers look. It can help further define important parts of your photograph as well as create a higher quality image when done properly. The right (or wrong type) of picture frame can also impact how the viewer looks at your picture so make sure to stick with a frame that has simple clean lines and avoid highly decorative, beaded or jeweled picture frames.

Use the “pure white, pure black” rule in every picture and you’ll see a huge difference in the prints you will produce. Once you understand what degree of contrast works in your photos, you’ll start to see how you can use contrast in the real world to shoot even better pictures. As always, the best way to get better is to shoot, shoot, shoot!

Digital Photography Basics - Types Of Photo Editing Software

Tuesday, July 27th, 2010

For anyone who loves taking pictures, it’s worth while getting acquainted with photo editing software as they can make a big difference with how your pictures turn out.

You can think of image software as the same to a digital photographer as the dark room is to a film photographer. The big benefit of photo editing software is that it’s easier to do than setting up a darkroom.

And with photo editing software, you can do standard image editing functions like cropping and adjusting color, and can also do photo manipulation.

Image editing refers to all changes that are made to a photograph. Photo manipulation refers to what film shutterbugs used to call “trick photography” switching backgrounds and such. (For some fun examples of photo manipulation, look up the “National Geographic Photo Foolery” page online.)

Once you know the type of image editing you want to do, you will be better able to choose a photo editor. In this article, we will highlight the most popular types of photo editing software so you can understand the differences between each of them.

Picasa: A free photo editor from Google. If you are just starting to learn the digital photography basics, then this will serve you well for a while. It’s really intended to be more of a photo manager and online photo album both very handy applications, but Picasa also handles the most basic editing. Picasa offers basic editing functions like retouching where you can remove scratches or blemishes. Like many photo editors it has red eye remover. It also has some fun functionality where you can create screensavers with your photos and even integrate them with Google Earth.

If you’re ready to advance from digital photography basics and do more with your images, consider one of the other photo editors.

Adobe Photoshop Elements: This is more user-friendly and less costly than it’s “big brother” Photoshop CS4 and is the market leader in photo editing and manipulation. It’s good for the photography enthusiast plus there is a free trial version.

Adobe Photoshop CS4: This has everything you could possibly need as a professional photographer or graphic artist. It sells for approximately $700 on their site, but it’s offered for half that by some vendors and may offer a free trial version.

Paint Shop Pro : This is a direct competitor of Photoshop Elements and also costs about $90. They also offer a free 30-day trial.

The GIMP: For such a powerful program the name certainly doesn’t fit it but instead is an acronym for GNU Image Manipulation Program. This photo editor is open source (aka freeware) and continues to improve and has a good community of users if you need help. It is available for Windows (NT4, 2000/XP/Vista), Mac Operating Systems (OS X) and even Unix/Linux platforms. It doesn’t quite have everything that you get with Adobe Photoshop CS4, but it has more than Elements or Paint Shop Pro and is used by some professionals.

No matter what photo editor you have, read through the guide or help sections so you understand what you can do with it.

It takes time to learn but you will be impressed with what you can do with your images.

For example, here are a just a few of the things you can accomplish (the top 5 even with just Picasa):

  • Crop
  • Resize
  • Lighten or darken shadows, highlights, and midtones
  • Correct Colors
  • Remove blemishes, a stray branch, a logo, or anything else you don’t want in the picture
  • Blur Backgrounds (Photoshop Elements, Paintshop Pro and The GIMP all offer background-blurring applications. Picasa can’t do this.)

You can also create all sorts of special effects with a photo editor. For example you can turn your photo into an impressionistic painting. You can also convert a color picture into a black and white image to better capture the tones and highlights.
Or for a more vintage or antique look, you can choose sepia.

And with photo editing software, you can also more easily create pictures that can go in any size picture frame whether it’s a small picture frame or a 4×6 picture frame or larger.

Even if you don’t want to do any cool special effects, learning the basics of any photo editor will let you fix “mistakes” in your photos. Just cropping alone can do wonders if you couldn’t get a close enough shot or you’ve got too much clutter in the picture. For these reasons image editing is part of just about any digital photography basics course or book you might find. Before long, you will be editing and producing quality photographs that you will be proud to display in a metal photo frame and hang on your wall.

Photography Tips: Five Tips for Beginning Photographers

Saturday, April 10th, 2010

While you can’t obviously learn everything in one photo article, this article gives you five basic tips to start using right away. Whether you have a point and shoot camera or are the proud owner of an SLR, there are a few basic concepts that once understood will get you on your way towards taking excellent photos. Here are five important and easy to use tips that you can put to use right away.

1) Resolve to Have Enough Resolution

Yes, a low resolution setting saves space on your memory card, but it doesn’t make for suitable prints. You can easily resize for a smaller picture, even in free programs like Picasa (”resize” is hidden there under “export”), but making a picture larger usually brings awful results. When you enlarge the picture, the pixels that make up the image are spread thinner.

If you like printing your images, choose medium or high resolution. Depending on your camera, 3 megapixels should give you high quality 4×6 images and sometimes even a very nice 8×10. For excellent quality 11×14’s go for 6 megapixels.

2) Let There be Light (but Make it the Right Kind)

Natural lighting is almost always best so don’t worry if you don’t have a flash or any fancy equipment. If your only flash is the built-in one, that’s all the more reason to opt for natural light. Built-in flashes can make subjects look flat. That’s why the pros use an external flash and bounce light off the umbrellas. There are tricks you can use like wearing a white shirt or taping foil to the camera to bounce the light off the ceiling, but if you want an easy way to get professional quality photos without the equipment, go outdoors.

When taking pictures outdoors, consider the position of the sun. With the exception of sunrise and dawn, the lower the sun is in the sky the better. You should also try to avoid noon as this time brings the harshest shadows. Unless the sky is part of your photograph, bright overcast days produce the best light.

3) Compose a Perfect Picture

Getting a fast snapshot of something without any thought mostly depends upon luck. But by first learning how to compose a photo, you will end up with more pictures that look good and are suitable for framing. The pictures you take will look more like what you had in mind when you clicked the shutter release.

There is a lot to learn about photo composition, but for starters, here is the number one rule. Fill the frame of the viewfinder. First, decide on what is the most important subject in your photo and then move close enough (or zoom-optical zoom is best) to fill the viewfinder with the subject. For example, if the subject is your grandmother watering her petunias then that’s the subject not her entire yard. Many make the mistake of losing their subjects in the landscape.

4) Steady Now

It doesn’t take much camera movement to create a blur, in fact most times, you’ll never even notice the movement until you see the blurry picture. For sharp photographs, keep your elbows down, feet apart and hold the camera steady while pressing (not punching) the shutter release. Continue holding still until the light indicates the camera has finished taking the picture. When you are taking a photo that needs a slower than usual shutter speed, like a fireworks display, use a tripod to steady the camera. You can also use other items as props to set your camera on as long as you have a remote shutter release. A good rule of thumb is to use a tripod for shutter speeds slower than 1/60.

5) Share Your Creations

If your photos are digital, use a photo editor to bring copies (save originals) of your photos down to the appropriate size for your website, email, photo album or picture frame. Use photo-printing paper that is compatible with your printer model. If you’re using a film camera but want photos for email or a website, use a quality scanner or when dropping off film to be developed, request a CD. 

Frame your best photographs and display them in a decorative wood picture frame. A picture framed in a classic silver picture frame also makes a very welcome gift, especially when it is a portrait of someone special. Remember a portrait can be of a single person, family, multiple friends or a beloved pet…the list is endless, and again, these make lovely gifts, especially when framed nicely.

By using these 5 tips you’ll help to expand your photography knowledge so you can continue to take even better looking photographs.

Photography 101: How to Understand Aperture

Sunday, April 4th, 2010

Aperture and other photo basics can induce yawns in the most eager of new shutterbugs, but once these basics are understood, the rest of photography comes easily into focus. Aperture, ISO and shutter speed are all important terms to know, whether you have a point-and-shoot or a professional camera. This article explains the basics of aperture and provides tips on how to use it to take better pictures that you’ll be proud to display on your wall in a hanging picture frame.

To best understand aperture, consider how the irises of your eyes widen and narrow to allow more or less light into the pupil. Like your irises, the camera’s lens diaphragm widens and narrows to let in more or less light. Thus the aperture determines the exposure of the picture, that is how bright or dark it is. The aperture also has another important function which we’ll look at shortly.

“Aperture” refers to the size of this opening and is measured in F stops. The smaller the F stop, the wider the aperture. This is why it can be confusing. Actually the F stop numbers represent ratios, which is why the larger the F stop number, the smaller the aperture.

In addition to controlling light, aperture also controls depth of field. To better understand this, make a fist and hold it in front of your eye. Now gradually open your hand. See how the focus changes as you open your hand? Sure you can see more through the larger opening, but notice how when the opening in your fist was small, everything that you could see was equally in focus? Try it again, and notice how when you open your fist, the object closest to you will come into sharp focus while objects farther away will be out of focus. This is how aperture determines depth of field, that is how much of a photograph is focused.

If you are taking pictures in Auto Focus (AF), the camera will attempt to focus on what it sees as the main subject, but often it may not be what you want.

For this reason, many cameras have an Aperture Priority setting to help eliminate this problem. This allows you to set the aperture and then it automatically adjusts the shutter speed to compensate for the larger or smaller aperture. For example, if you set the aperture for a landscape, it narrows it and therefore lets in less light. The camera would automatically lengthen the time the shutter stays open so that your photo isn’t underexposed (too dark). Aperture Priority isn’t perfect, but generally this how it works.

Now if you have an SLR and are taking pictures in manual mode, you can adjust the shutter speeds and aperture separately.

Most will have a camera with preset modes such as landscape, sports or portrait. When the mode is set for landscape, the aperture automatically narrows so everything will be brought into focus. At the same time, the shutter speed automatically slows down, leaving the shutter open longer to offset the smaller amount of light coming through the lens diaphragm.

When you switch to portrait mode and focus on someone in front of you with the landscape in the background, the camera will make your subject in focus and make them stand out from the background. And it will speed up the shutter speed so the picture isn’t overexposed by the additional light allowed in with the larger aperture.

Remember: the smaller the aperture, the greater the F stop number (because it represents a ratio not a whole number) and the greater the depth of field.

Understanding photo basics like aperture is super important for using manual settings or aperture priority but also helps those using preset modes as well. Here are three preset modes you should better understand:

  • Portrait: How much the background blurs when using this mode depends on your camera and the distance between your subject and background – a minimum of 10 feet works best. This mode can be used for any subject you want to bring into focus while taking the background out of focus.
  • Landscape (also called “infinity” on some cameras) is the mode represented by a mountain peak or a figure 8. You can use this for anything where you want everything in the picture to be in focus, such as seascapes, cityscapes or your garden. And for shots of breathtaking vistas, try framing them in a panoramic picture frame to make your images really stand out.
  • Macro: This mode, often depicted by a tulip opens the camera’s aperture extra wide so you can take super close ups. Depending upon your camera, you should be able to get anywhere between an inch to a foot of your subject. When preparing to take photos outdoors of items like flowers, remember that even the smallest petal movement can cause the image to be blurry because of the slower shutter speed. Also remember to focus on the part of the subject that you want most in focus, whether it be a butterfly’s wing or a caterpillar’s eyes.

Just applying this knowledge can help you produce some beautiful photographs that you’ll be proud to display in a gallery picture frame on the wall.

8 Benefits of Why You Should Learn Photography

Tuesday, March 9th, 2010

So you’re interested in starting to learn photography –  congratulations! Photography is a wonderful practical hobby as well as an exciting career opportunity. Learning photography takes a little bit of patience but in the end it’s all worth it. Let’s start with the reasons why you should learn photography:

  • The chance to capture special events like a special birthday or the family vacation with clear, well composed pictures.
  • Never missing another “Kodak moment” while searching for the right dial or button.
  • Taking beautiful photographs that you and your loved ones proudly frame and display.
  • Communicating through your photographs. A picture really is worth a thousand words (especially if you put it in a beautiful jeweled picture frame)! You can capture an expression that says it all. Or as we’ve seen in magazines like Time and National Geographic, you can shoot photographs that convey messages powerful enough to open a mind or convey just about anything you want to communicate. You don’t have to be a professional photojournalist to get out there and take some great shots.
  • The ability to take a portrait photograph in a home or outdoor setting that captures the unique personality and beauty of a loved one – the type of portrait that uplifts the person and makes them want to see the portrait framed on the wall, not hidden at the bottom of a box.
  • Excitement! With a good telephoto lens you can, from a safe distance, capture exciting shots of wildlife and weather phenomena. Picture your friends reactions when they see your photographs beautifully framed on your wall.
  • Fun! It’s fun to take photographs of people, places and things we love. It’s even more fun to take pictures after learning just a few skills!
  • Fame and Fortune! Many a hobbyist photographer has gone on to win ribbons, awards and make money by selling their prints online with or without frames. Others photographers sell downloads at photo sites like iStock. Some take pet pictures of their friends pets and get their business started from there. Others become wedding photographers or get jobs working as photographers.

You may have some goals in mind that weren’t listed here. As mentioned the rewards of taking pictures are numerous. To get started taking pictures, all you need is a good (not expensive) camera and a few basic skills and you’ll be well on your way.
