D-SLR, professional camera

June 10, 2009 RENU

  1. Digital Single Lens Reflex. Similar in design to SLRs of the 70s & 80s but using digital sensors instead of film.
  2. Most widely being used now, powerful,  exceptional picture qlty, easy to use, available for all levels of interest & expertise i.e weekender to professional, offer wide range of features, enduring value, good for creativity.
  3. Big advg’s- Speed, Power, Range. 
  4. Speed- Swift start-up, shutter response, autofocus & framing rate for continuous shooting. There is no shooting lag that occurs between the time you push shutter button & the time the picture is actually taken so you will capture those perfect moments other cameras miss.
  5. Power- Its sensor is bigger, which means its pixels are bigger, which means higher overall picture qlty. Some can analyze the lighting, color, contrast of a scene, instantly refer database & imm’ly choose the correct exposure-even in the most challenging lighting situations. High ISO sensitivity makes once impossible low-light pictures now commonplace.
  6. Range- Offer lens choices from ultra wide angles to super telephotos.  
  7. SLR allows you to ‘see’ through the lens, thereby getting a first hand insight into the depth of field & composition.
  8. Nikon & Canon top the list of digital SLRs. Nikon’s D-700, recently launched & D-90 are the talk of the town today.
  9. Do keep your reqt in mind before you spend a lot of money on a new camera. If you are a hobbyist, you may never use some of the features such as extremely high shutter speeds, offered in the pro models. 
  10. Nikon D-40x, a 12 megapixel camera, is moderately priced, more than adequate to learn photography with, as well as shoot your basic assignments.
  11. Always use a tripod, especially on shutter speeds lower than 1/100 second.
  12. Take the time to compose your frame – resist the urge to fire away at everything that you see. Do get a few shots, then rethink, re frame, re compose, THINK how you have arranged the subjects in your frame & why…
  13. Visualize -especially for studio photography & landscapes. The lighting set up, the exposure points, the filter, the lens, the film/ISO level, the shoot timing, the model make up & costumes, the photo editing stage, finally the presentation. When you are able to break it up into segments like this, you will have a ctrl over photography. 
  14. There are more uses to a UV filter than simply blocking out the UV rays. Filter costs you only a fraction of the amount you paid for your lens. Keep a UV filter attached to every lens that you have (considering it is an SLR of course). If you happen to scratch the ‘lens’ surface, you have only damaged the cheap filter & not lens surface.
  15. To blur out the backgrounds & fore grounds & isolate subject, you should understand the depth of field of the lens at the given aperture. When you focus on an object, there is an area in front of the subject as well as behind the subject that are both ‘in focus’ up to a point. Objects in front of the subject will gradually fall more out of focus the closer they are to you (and the further they are from the point of focus). This gradual change in the sharpness or ‘unsharpness’ of objects is what we call the depth of field or ‘d.o.f.’ of the lens at the given aperture. When you are able to get your backgrounds (or foregrounds) out of focus at will, you have become a better photographer. But need to change shutter speed to compensate for the increased or decreased amount of light that is allowed to enter the lens, with the change in aperture. Another factor which has an impact of depth of field is the focal length of the lens. A longer focal length i.e ’zoomed in’, produces a shallower depth of field. A wide angle lens has the exact opposite affect & produces a larger depth of field – directly proportional to the ‘wideness’ or shorter focal length. So – the shorter the lens focal length the more the depth of field, the longer the focal length the less depth of field. Also – the larger the aperture the less the depth of field, the smaller the aperture…. Use focal length & aperture to control your d.o.f.
