1. Working Notes Introduction to Digital SLR Photography Introduction These notes complement the material presented in the the Nikon School of Photography Introduction to Digital SLR Photography seminar Useful Web Sites Wwww nikonusa com www capturenx com Goals for the Day Whether you ve just bought your first camera or have been shooting photos for fifty years your goal is the same to make nice photos In the last ten years there have been amazing changes to photography but it still comes down to finding a good scene and making a well exposed in focus picture from it The purpose of this seminar is to help you understand not only some of the changes digital pho tography has brought to us but learn how to better control the camera and how to think about what and how you are shooting Workflow Digital workflow is just a fancy way of referring to the steps you take with your digital images There are endless ways to get from start to finish and the Workflow that s best for you is the simplest combination of steps that fits your needs Whether you still shoot film or are shooting digital the general process remains the same e Prep e Shoot e Process e Sort File e Edit e Show Share Art and Craft There are two aspects to successful photography art and craft Really we should say craft and art because without mastering the craft of photography the technical side we ll never be able to realize the2. d get with a 75mm lens although it s still a 50mm lens with all of the same lens characteristics and perform ance such as depth of field In early digital cameras the downside was the diffi culty in getting extreme wide angle views That s been overcome with the introduc tion of lenses built specifically for these digital cameras such as the 12 24mm DX and 10 5mm DX lenses Now Nikon is making cameras D3 and D700 at this time that have what Nikon calls FX sensors that are approximately the size of a 35mm piece of film With these cameras there s no crop factor so the field of view of a 50mm lens looks just like it did on a 35mm film camera Using a DX lens on an FX might cause vignetting at the edges so Nikon s added a menu item that s on by default reduc ing the capture area of the sensor when a DX lens is used on those cameras What s all this mean for Nikon photographers More choices The larger sensor used on the D3 and D700 are great for wide angle lenses and offer superior high ISO performance The DX bodies such as the D300 D200 D90 and such allow photographers to get even more reach out of telephoto lenses and take advantage of smaller DX lenses The Craft of Photography We started by talking about how to manage the controls of the camera so we could get technically competent photos Now it s time to look at the creative side of things Before we consider the more traditional techniques let s look at
3. artistic side that lives within each of us Therefore first we need to understand how cameras work and how to control them Once we ve begun to master that we can then move on to fulfilling our creative vision Exposure Controls Since the beginning of photography there have been three components for control ling exposure ISO This describes the sensitivity of the film or sensor Lower numbers mean you need more light higher numbers mean you can make the same exposure with less light The downside to higher numbers is the resulting grain film or noise digital Therefore the first rule is to work at the lowest ISO setting you can and still get the photo not so low that your photos are blurry Remember that every camera will produce its best quality at the lowest ISO setting it offers but you may not be able to make the photo at that ISO setting Auto ISO available on most cameras now can be an easy way to get started Shutter speed and aperture These two controls determine how much light reaches the film or sensor Higher shutter speeds let less light in lower shutter speeds let more light in Higher shutter speeds can stop action lower shutter speeds can result in blurry intention ally or unintentionally pictures 1 1000 second is a very short shutter speed high number and can even freeze the blades of a helicopter 1 30 second is fairly slow so that a photo of a person walking would show some blur Here s an eas
4. in a way that you want for the feel of the photo This is a wonderful way to work a different effect into your photos and well worth taking some time to explore Remember that the best way to learn to use a new feature is to play with it With a digital camera you don t need to worry about wasting film and can see your results immediately Try shooting a sunset with the Incandescent setting Fluorescent setting or one of the many others Technical Concerns From the technical side there are three things you have to be concerned with when taking pictures 1 Do you have a good exposure 2 Is the shutter speed sufficient to prevent unintentional blur 3 Is the image in focus where you want the focus to be After you ve mastered these three issues you re ready to move on to the creative side of photography Exercises The best way to learn your camera and expand your photographic talents are to practice and experiment Take some time and try these Shoot an action scene at high and low shutter speeds See what happens when you shoot the same scene at high and low ISO Shoot a subject at high and low apertures with wide angle and telephoto lenses from the same distance away Shoot a scene at normal exposure then use exposure compensation to go 2 1 1 and 2 Shoot scenes indoors and out with flash ON and flash OFF Try the different AF options your camera offers to see what works best for yo
5. is made up of different color temperatures While our visual system eyes and brain working together rarely sees it that color tempera ture affects how a camera records color Most film was daylight balanced and we would filter for changes in color Digital cameras make this much easier through their white balance controls All digital cameras use a feature called Auto White Balance to determine how to process the color in a scene For the most part this works very well and some peo ple never take the camera off that setting There are times though when you might want to explore the other options available There are two reasons you might want to do this to get the color right or to create more interesting color 13 Get the color right Most digital cameras produce images with a warm cast yellow ish or Orange in incandescent light such as household lighting Some people like the resulting look while others don t To get rid of it try switching to the Incandescent setting in your camera s white balance menu You can also try using the Preset White Balance where you ll go through a small set of steps to have the camera determine the correct white balance to apply to the scene This is the most exact way to get the color right Check the manual for your camera for the exact steps to take Create interesting color The other option with white balance settings is to use them as a Creative tool to change the color

8. time to visit museums to study art and look at books of photography you admire The Basics It often feels that there are just too many things to be thinking about when trying to take photos One way to deal with that is to try to reduce that number to a manageable group Here s one way to approach that 1 Subject What is your subject Think about what exactly caught your eye and what s the best way to show that It may mean you need to change your position move closer move higher or lower or change lenses Think about the framing composition and whether what you ve included in your viewfinder is really what you want to capture Po Background Does the background add to the subject or distract from it Is it too light or too dark Again changing your position or lens may make for a better photo oo Light Light is often more interesting when coming from the side or even from behind the subject It also has many qualities such as hard soft or color If you have time walk all the way around the subject and look at how the light changes the scene This is also a great way to look at different back grounds In some cases you may want to come back at a different time of day or wait for clouds to arrive or depart Whenever you see a photo you like think about what the photographer did to make it that way Look at how they used lens choice subject angle composition and background to create that photo
9. to start using the Unsharp Mask Filter It s complicated but there are lots of how to s about it on the web Printing Choices There are plenty of inkjet printers to choose from Actually there are too many right Here are the key things to look for in a printer It must have at least six inks to produce photo quality prints Less and you ll probably be disappointed with the results Don t get too wrapped up in DPI ratings Dots Per Inch refers to the number of ink droplets a printer can spray in a One square inch area and 720 DPI is considered photo quality Some papers require higher DPI but it s doubtful you ll use more than 1440 even if your printer supports it Ink drops are measured as picoliters They re tiny and the difference between a 2 picoliter droplet and a 4 picoliter droplet is not a big deal More important is that the printer use variable droplet size technology which most good photo printers do Unless your business is making prints don t get too wrapped up in speed rat ings A good print is always better than a fast one Some printers use pigment inks and those inks give a longer life The rest of the printers use dye based inks whose prints may not last as long but give vivid colors The good news on dye inks is that the manufacturers are pushing the lifespan of their ink and paper combinations into the decades which is more than enough for most people and most common in consumer level
10. Some photos are simply a matter of being in the right place at the right time and pushing the button but most are a conscious creation of the person behind the camera Exercises The best way to know your camera and expand your photographic talents are to practice and experiment Take some time and try these exercises Use the different Scene Modes and try Program Aperture and Shutter Priority modes 16 Take the same scene and shoot it with different white balance settings See how tight you can shoot a subject and how that changes the photo Spend a day shooting everything with both your longest telephoto and your widest wide angle lenses Shoot the same scene at different times throughout the day Same scene but from different angles Image Editing Editing or enhancing images is different from browsing An editing program is designed to help you change color and tone create selections crop change resolu tion and a myriad of other controls It s important to always remember the adage garbage in garbage out In other words it s much easier to make a nice picture beautiful than try to rescusitate a photo that s badly exposed or worse out of focus Everything you do to an image in an editor unless working on a NEF RAW file takes information away You may be able to make the photo look better but that comes at the expense of losing data that you may need especially for printing With that in mi

12. arlier It s a good idea to check Nikon s website every few months to see that you have the most recent firmware Histogram The histogram is a visual readout of the exposure of an image It s an incredibly useful tool for understanding whether you need to make changes in how you re capturing a scene With some cameras it s always on but others require you to turn it on in the menus Also many cameras now offer an RGB histogram as well While it s pretty the standard black and white Luminance histogram is generally easier to use It s also one of several screens of informa tion available on each image from the back of your camera similar to the Highlight alert Understanding Metering Modern camera metering systems have gotten much more accurate over the last twenty years thanks to improvements such as Matrix metering These new systems are very effective at giving an exposure at least close to what the photographer might want However it s important to remember that there s no brain behind the metering and it might not record the scene the way you want it to For that you might want to turn to Exposure Compensation Exposure Compensation Understanding how camera meters come up with the exposure they do can help you be more effective in using that information Simply said the meter is looking at the scene information and trying to expose to achieve a middle gray A good experi ment to help understand this is to photogra
13. blowing around Never leave the camera without a lens or body cap on it The simplest way to avoid problems with dust it to get in the habit of blowing off the sensor regularly with a hand blower Avoid compressed air as it can be too forceful and can actually spray foreign matter onto the sensor If your sensor gets dirty to the point that blowing doesn t clean it you should consider sending it in to Nikon for a thorough physical cleaning Some of Nikon s newer cameras have a sensor cleaning routine built into them but you still need to do all you can to avoid letting dust in Exposure Modes give you different ways of controlling the exposure All digital SLRs offer several choices Auto Exposure is an exposure mode where the camera will try to determine the correct combination of aperture and shutter speed and in most cases ISO to give you a good exposure It s a good starting point for most people but tends to give you the least control over how the camera works Scene Modes Compact digital cameras have offered Scene Modes for years and now some digital SLRs do as well Scene Modes simply set the camera to work in a specific way to get a specific effect Some Nikon cameras have these and they re called Vari Program modes All of these effects can be gotten the old fashioned way by setting the controls on the camera to get that result These modes simply automate that The general ones are as follows Night Portrait
