If you are interested in digital photography and want top quality photographs you could do worse than look at purchasing a single lens reflex (SLR) camera. Successful digital photography with SLR cameras is achievable even by those relatively new to the medium. Firstly you should understand how this type of camera operates and how you can influence the outcome by choosing the exposure rather than using the auto function. It may take a little more work at first but the images that a digital single lens reflex (DSLR) can produce far outweigh those produced by a point and shoot compact digital camera.A DSLR has a mirror that directs the light entering the lens up onto a prism for you to view the image. Once you press the shutter release the mirror pivots up out of the way just as the exposure is made. This is the same movement used in a traditional film SLR. To aide viewing the image the aperture remains at its maximum, for example f2.8 this allows the maximum amount of light to enter the lens. However, when you press the shutter the aperture will stop down to the required calibration (pre-adjusted) so that the combination of the aperture and the amount of time the shutter is open (speed) is combined to make the exposure. You have control over how the image will be recorded. for example, a larger aperture in combination with the required speed may throw the background out of focus and make the main subject of the shot more prominent.The different camera manufacturers provide a wide variety of interchangeable lenses from which to choose. However, it is not usually possible to use a lens from one manufacturer on a different camera. There are lens manufacturers that do produce different fittings for various cameras. A dedicated lens from a specific manufacturer such as Canon or Nikon will usually be more expensive than a lens from this type of manufacture but the quality is often comparable today.With an SLR you are easily able to view the scene in front of you as is. This means that if you place a filter over the front of the lens you will be able to view how this alters the image, you will also be able to see if you have left the lens cap on!There are some disadvantages to using a single lens reflex camera, notably the weight. The prism and the optics do add to the overall weight of the camera and you may need to have a strong camera bag and even a tripod to use it if you are using a long telephoto lens. These cameras can also be noisy when the prism lifts up out of the way when you are taking your shot.For successful digital photography with an SLR you need to get to know your camera as well as possible so that you can easily use all the options available rather than have to keep looking at the instruction book. If you put some little time into doing this the results you achieve will far outweigh your best shots taken with a digital compact camera.
Continuing Education for Nurses
The following article relates not only to nurses but also to those aspiring to enter the noble profession of nursing. We hope you will get some insight into this field.Although we have used the female reference for nurses throughout this article (“she”, “her”), this is done purely for convenience and in no way reflects the gender status of nurses in today’s society.Most people assume that once a nurse has completed her education and has become registered, that is the “end” and that no more learning or education is required. This couldn’t be further from the truth. There’s more to nursing then just tending and looking after patients.It is highly critical that a nurse maintain and continue her ongoing education and is kept current on her profession. This is an integral part of maintaining her registration.A nurse’s life in the 21st century is extremely fast paced. There are medical advances in precedures almost on a daily basis and it is essential that a nurse is kept abreast and is at the forefront of these improvements. This requires a high level of time management and dedication to improve oneself in addition to spending long hours in clinics and hospitals. Of course this is much easier said than done.It is in the best interests of a good hospital to provide everything needed for nurses to continue their education. A good hospital will also more than likely pay for the education of their nurses. A lack of funds should not be a deterrent to a nurse continuing her education.Many nurses regularly subscribe to nursing periodicals and magazines to keep up to date with their ongoing education.. Nurses are encouraged to go through the relavent published journals on a regular basis.Of course let’s not forget that just as important to success is the keeping of portfolios and timely documentation detailing all the training and education received throughout the nursing career. This written journal also serves as a method of organizing in an orderly manner, all the continuing education undertaken.Admittedly, there exists a challenge with regards to access to this education for nurses, namely the expense, since nursing is still not considered to be among the better paid professions. This challenge to accessibility can perhaps be met by employers coming forward and funding the continuing education of registered nurses.Please be sure to check out the many additional resources available on this topic online.
