Infrared Photography and Big City Crime
One of the major problems of the larger cities of the word these days is crime. It appears that the larger the city the more-acceptable serious crime seems to be. If not because to the proliferation of serious crime then because the mindset of its citizens have been conditioned to accept the serious behaviour of a minority of its inhabitants. So, how does this statement relate to infrared digital photography and the hobbyist or professional camera operator? Not much escapes the all-seeing eye of the infrared camera of the police helicopter as it chases a carload of thieves down the freeway in the middle of the night. They will almost invariably be caught by the police when they exit their vehicle thanks to the thermal heat imaging of the helicopter's infrared camera. Likewise, your own infrared daytime photography should let no entity go unnoticed. After all ? you've spent a lot of time setting up the shot and composing the image with just the right light, shutter speed and aperture. Your mindset should not be to simply accept inaccuracies and faults with your photograph, but to go that extra step to eliminate them altogether. Just like the officers in the police chopper, why would you go to great lengths to capture that final important infrared image only to decide at the last second to give up the chase? Digital infrared photography does have a few things that should be taken into account to ensure your image is as best as could be. The following combination of items will affect your image: Light, Dust on the infrared filter, Type of infrared filter, Exposure setting, Aperture and Movement of the subject The digital infrared images at Photo Shop Australia http://www.PhotoShopAustralia.com/ have varying amounts of light, shutter speeds and apertures. Low light may require longer exposure times if you can't get the aperture down low enough. This could have a dramatic effect on the final image ? especially if you are shooting a subject that may move even slightly. Dust on the infrared filter will affect the image by producing "blind spots" in the final image. A close inspection of your infrared image in your photo editing software will reveal these. The blind spots can be smudged out of the image easily, but if you have hundreds then it may be more worthwhile to recompose the image than to edit the digital photo. The type of infrared filter will also determine the outcome of the print. The Hoya R70 filter seems to be the best-priced for digital infrared photography. Exposure and aperture settings can be played with until you find the best combination for your camera. But keep in mind that usually the higher the F-stop the longer the shutter speed required. So shooting a moving subject at a long shutter speed can result in unwanted effects. Long shutter speeds (of up to 15 seconds or more) of trees on a windy day can actually produce the most spectacular effects. We've all seen those long exposure night photographs of cars moving along a freeway. Long exposure daytime digital infrared imaging can produce amazing results too. You just have to get creative with your camera and subjects. Think of the possibilities! Be aware that adding an infrared filter may have serious effects on your camera's electronics or lens. Consult your camera's operations manual or manufacturer before fitting any infrared filter to your camera, and never look through an infrared or any other type of filter with your own eyes.

Travel and Scenic Photography 101 When you're driving through the mountains somewhere, and you notice a car parked half off the road and some guy leaning to the left to avoid a branch with his Rebel 2000 camera in the act of focusing, you've met me. I do this because, to me, a trip isn't fulfilling unless I've preserved that beauty for posterity. I'd like to share some of the techniques that make scenic photography such a wonderful artform - simple, yet elegant.First off, equipment. As much as the cheapo disposable camera beckons, get real. These cameras have fisheye lenses which I call "spam" lenses. They cram everything in, with equal blurriness and boringness. Good photos are sharp, unless you use blur for artistic effect. Sharp comes from an adjustable lens. It can be a fixed lens or a zoom, but it must focus specially for each picture. Fixed lenses are limiting for scenic pictures, where to frame the shot you may need to move long distances. Imagine using a fixed lens on the Washington Monument, when you're half a block away! Zooms get my vote, even though they often don't have as wide an aperture, which limits their capabilities in low light situations. Practically speaking, an SLR is the absolute best. They are lightweight, and can be used with top quality lenses. Film SLRs tend to be less expensive, but have the limitations of film, meaning you have to get it developed and so forth. Digital SLRs are VERY expensive, so for the budget conscious either go with a film SLR or a high quality basic digital camera. With digital, resolution is also a critical factor, so look at the specs before you buy.OK, we've got the camera, emotions are running high, and that's great, but not too great! Sometimes I find a spot that is so wonderful, I start shooting like a madman, only to be disappointed by the pictures. What happened? Emotions. When you experience a place, there are sounds, aromas and breezes as well as the visuals of the spot. Needless to say, you can't photograph all of these elements, only the visual. When overwhelmed by the spectacle of a scenic hotspot, we are often overwhelmed by all of these elements.So what to do? Look through your camera. The viewfinder does not lie (usually). Try to see what you are looking at as the finished picture. Most people perfunctorily take pictures, hoping that somehow the shot will come out great. If you wonder how the pictures came out when you are on the way to the drug store to get them, you're doing something wrong. At the moment you click the pic, you should know exactly what you will get. (Of course with digital, that's not a trick!). Now, I was a tad dishonest in saying that you can't capture all of the elements of a scene. You can hint at them. For starters, motion. Yes, even in a still picture, there is motion. Something happened before, during and after your picture. In a mountain vista scene, you may find something that hints at motion, whether it be a branch of a tree that has been swaying in the breeze, or a river flowing through the valley below. These add a sense of motion. Then there's the "rule of thirds." When you place the main object of the picture smack-dab in the middle, it is static and boring. Place it one third of the way from either side, and you IMPLY motion. Put the horizon in a landscape photo a third of the way up or down, not across the middle.Remember, when a person looks at a picture, their eyes move. You want to frame your photo to help that movement. If you can find some lines in the scene, such as a skyline, cloud formation, path through the forest, etcetera, use it interestingly, and with the rule of thirds to draw your viewer's eyes into the picture.Avoid "summit syndrome." You get to the top of Mount Washington and shoot the majestic vista. Great. The pictures come out ... boring! How? No PERSPECTIVE. Big vistas will be flat unless you have an object in the foreground, such as a rock or a tree, to give them perspective. Then the eye really grasps how big this scene is. People enjoying the view is a real winner, because the viewer may identify with their emotions, giving the image real impact.Cheese! Yes, you do have to take the family photos. It's obligatory. But when you do, make sure that they show the LOCATION of the photo. Otherwise, you might as well do it on your driveway. Frame the scene in context, with landmarks as part of the picture. Find a way to tell as story in the picture, such as little Sara climbing up the rocks by the waterfall.Finally, any element in the picture that hints at more senses than just the visual will make it remarkable. Actor headshots for example, tell a story about the subject. You can almost hear them saying their next lines. If you photograph a garden, the viewer may experience the aroma of the flowers. A tourist street with an accordion player on the corner may have your amazed friends whistling "Dixie."In summation, picture taking on travel is recording the experience in a satisfying way. Use motion, perspective, sensory, storytelling and so forth, to bring your photos to life. Oh, and needless to say, make your job easy and go to great places! See you at the overlook! How Can I Preserve My Lifetime of Memories in Photographs? Like most folks you have probably have organized and sorted your photos atleast once. The problem is they never seem to stay organized no matter how hard you try, and even if they do they seem to lack that original impact that they had shortly after you took them or if they do, you never drag them out until sadly, someone passes on. Selecting Good Stock Photography in the Age of Digital The business of stock photography has drastically changed over the last few years. Ten years ago, selecting photographs for your brochure or newsletter meant spending hours pouring over stock photography catalogs and ordering photo research to find the exact image. When the order came in a giant overnight package, designers would spread transparencies out on the light table, squinting through a magnifying loop to check every detail. How To Reduce Red Eye The Easy Way With Any Pro Or Point & Shot Camera There is one simple technique any body can do to eliminate red eye. It can be done with any type of flash on any camera because red eye only happens when using flash. Red eye is the result of a burst of light causing the reflection from the back of the eye blood vessel. I'm not a doctor or an expert on eyes but you get the idea. Is Film Better than Digital for Weddings? As a professional wedding photographer I get this question asked more than anything else. Rarely will somebody ask me about my wedding photography education, awards, or professional memberships. I believe the root to this question lies on misinformation about the different qualities of film and digital. Using Film Speed Effectively (Black & White Film Thoughts) It's hard to find sometimes but it's making a resurgence, black and white film. If you've never used this film now is the time to try it out. Here are some tips to using b&w film and what you can expect from the results. The Beauty of Nature Photography Nature is all around us, and its beauties are unlimited. In this fast-paced world of mocha-lattes and traffic jams at rush hour, too many of us take the beauty of nature for granted. Luckily, there are still people in the world who see this beauty and choose to share it with those of us that are too busy to normally take notice. Poets and photographers are great at this. They take what seems like the ordinary and present it to us in a way that shows us the elegance, the magnificence and the amazing that is on this rock we call Earth. Take Spectacular Nighttime Photos with your Digital Camera - Part I Night photographs express a special something that cannot be seen in normal daytime photography.

Start Up a Nude Photography Business There are major obstacles to overcome to get into nude photography, not least of which is the need to practise technique. By its very nature there has to be at least one subject, and the big problem for the photographer here is image. To some the image of nude photographer is tied in with the "dirty Macintosh" brigade, with the false wig and dark glasses. Picture Framing for Photographers - Part 2 There are two sources for obtaining the moulding for making a frame. You can firstly start with a straight piece of timber, and using a home routing system make your own moulding shape with a rebate to take the art work. Alternatively you can pick from a large range of ready finished mouldings available from your local frame shop or hardware store. I recommend the latter. It's easier, the choice is much wider, and it's more cost effective. However, one word of warning. Always look for a moulding with a good straight back and not too flat on the surface. If the moulding has a bump or some raised section in the top surface it will cut and join easier than a flat moulding. Most mouldings are made from pine or obeche. These are soft grain timbers and cut and join well. Hard timbers like ramin are more difficult to work with. Freelance Photography: How to Begin Your Career Photography is a vast world. There are many different types of photography and many different kinds of people that enjoy it. It's a hobby that be relatively inexpensive or one that you can invest a lot of money on.

Everybody is Fixing Their House or Apartment Up These Days. Use That Digital Camera to Capture That's right, you go through all the trouble of making your house or apartment nicer by hauling yourself off to the local fix it yourself store or hiring some professionals to come in and do it for you, so why not capture an accurate record of it for posterity.

And while the alligators are wonderful and plentiful at the place fondly referred to as the "Gator Farm," it is the birds that attract the world's best photographers. Digital Cameras & Resolution While analyzing any camera, one of the most important qualities of a photograph that a person seeks, is resolution. This word itself needs a brief discussion before progressing onto its implication upon a digital camera. This is a word that seems to almost every new photographer as a nightmare. With all the myths and irrelevant information circulating all around, this is quite common. This however is an effort to clear those misty myths and provide good information for everyone. Without any complexity, generally a photograph, either viewed on the screen or printed, is composed of infinitesimal dots (called pixels). The greater amount of these dots that can fit per inch of space, the smaller the dots and the sharper the image. This is the basis of understanding ... resolution! Seven Ways for Saving Your Digital Images Forever! So, you have taken lots of pictures with your new digital camera, the memory card is full, and you are wondering how to store and archive your images.
