Nowadays, according to psychologists, more and more people are getting visually inclined. In other words, most of us love to use our eyes!
In what ways do we use our eyes for?
We use our eyes to view things in our environment. However, through time, man has devised ways on how to preserve the things we see, whether these are beautiful or not, and one of which is by way of using cameras.
These days, the biggest sellers in the camera market are the so-called digital SLR cameras.
Just what is an SLR camera?
SLR is an acronym for Single Lens Reflex. SLR cameras were the tools made for and used by professional photographers. Cameras such as these, similarly, make use of mirror that reflects light entering the lens up into the eye piece or the viewfinder. Thus, a photographer can gauge how the image or picture will look like. Moreover, a SLR camera uses lenses that are interchangeable. Hence, this camera can be used for long distance telephoto photography or close-up macro photography.
A digital SLR or DSLR camera is dependent on lenses and mirror and their optical capabilities. However a DSLR camera uses light sensor chips and digital memory cards instead of films, basically a computerized version of the abovementioned camera.
The following summarizes the comparison between DSLR and point and shoot cameras (SLRs):
1. DSLRs and SLRs use interchangeable lenses for better resolution.
2. Any picture you take using SLRs and DSLRs is usually crisper, cleaner and fine upon reproduction.
3. DSLRs have a higher speed when it comes to focusing and taking pictures
4. DSLRs perform better at low lighting conditions by using ISO speeds. These cameras have lesser granularity.
5. DSLRS provide more professional power over depth of field, light, and responsiveness.
6. DSLRs provide a more immediate feedback as they use digital chips or light sensing CCDs that translate incoming light rays into digital pictures.
7. DSLRs and SLRs cost more than point and shoot cameras.
8. DSLRs and SLRs are usually heavier than some point and shoot models.
Some sample DSLR models are listed below:
• Canon EOS 10D
• Canon EOS Digital Rebel XT
• Nikon D50
• Nikon D70s
• Pentax *ist DS
• Canon EOS 1D Mark II
• Canon EOS 20D
• Fuji Finepix S3 Pro
• Nikon D2x
Who actually wants DSLRs? Anyone wants to have crisper and clearer pictures—be it a hobbyist or a professional photographer can opt for a DSLR model. Anyone who will not bother carrying bigger cameras on trips in order to bring back topnotch photos can make use of DSLRs.
Like all electronic and computerized gadgets, digital models tend to get cheaper yet better over time. For sure, DSLRs will eventually migrate down to consumer cameras: ability to take bursts of 10 frames in a few seconds, quick response time, higher resolution image sensors, and accurate auto-focus, among others.
The only thing that will remain constant are the laws of optics—you will not get the same results from a finger-nail sized lens as with larger lenses used by professional users. Also the fact that people do not have enough money all the time remains the same through time.
If you plan to take photography as a profession, practice shooting some shots using prosumers models and consider budget and quality of lenses before you say, “Big Cheese”!

Memories are created just about anywhere. And when I say anywhere, I mean that memories are even created underwater – so the creation of underwater digital camera.
An underwater digital camera is not just used to capture underwater memories; some professional marine photographers also use underwater digital cameras in their business. Even marine biologists and scientists use underwater digital cameras to capture marine life and thus be able to study the life and properties of the marine life. But I think it is safe to assume that you, my reader, are neither a marine scientist nor a professional photographer. Like me, you are just some photo junkie who wants to capture underwater moments and just cant figure out how without ruining your cameras.
Please listen to me when I say that even waterproof cameras cannot withstand underwater photography. To be waterproof is to resist the water in certain levels, submerging in under the water to get the perfect shot is like throwing it out of the window expecting a pick-up truck to pass by and run over it.
Now if you’re really serious about using an underwater digital camera to capture those wacky and funny moments underwater, I suggest that you buy specialty cameras.
There are rarely underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure. The closest electronics has ever got to producing underwater digital cameras are producing underwater casings for digital cameras. These casing will turn your conventional digital camera into an underwater digital camera.
If you are shooting with your underwater digital camera, you need to take note of a few things to help you come up with the best images underwater.
Remember that as you farther under water, light diffuses. This means that your underwater digital camera will produce images darker than those images you took while on land – this is because of the light diffusion the red spectrum seems darker. To avoid this, use white balance come up with natural colors. Also, pictures taken underwater will come up larger than pictures taken on land with the same zoom effect. Be sure to check your underwater digital camera’s viewfinder to check the right picture angle and size that you want.
An underwater digital camera with its built-in flash will produce marine show phenomenon. It is a phenomenon wherein your pictures come out as blurry and with white particles floating above it, to avoid this phenomenon it is advisable to use external flash for your underwater digital camera.
Before using your underwater digital camera, submerge the camera in the water first for several seconds then check if there are leaks through the case. Make sure that no grain of sand or piece of hair is stuck in between the seal to make sure that water will not permeate the case and thus wet your camera in the process. It is also advisable to put silica gel or two inside the case of your underwater digital camera as long as they don’t disturb the camera’s operation. (Silica gel will keep the moisture from forming inside your camera case.)
Most underwater digital cameras come with optional lenses. Don’t be afraid to add these lenses to your underwater digital camera kit. Macro lenses will help you capture small things without getting too close and startling your subject.
Also, remember to always wash of salt when you’ve used it under salt water. If the salts are not washed off, in time they will crystallize; act as sands and cause leaks for your camera case. In cases when sands seem to get into the case, they are better washed off with streams of water.
Check out Sony, Nikon and Canon’s website for available underwater cases for your digital cameras.

Have you ever wanted to find a way to bring extra money into your household--yet don’t have a lot of time to spend on a full-time endeavor? The solution is as close as the digital camera sitting there in a drawer. The following suggestions are only a few of the many ways you can make money in your spare time with your camera.
* Pet photos - Most owners won't struggle to take a photograph with their pet all by themselves. You can be the one who makes it easy on them. Not only can you charge for the service and your time, but you can offer the photograph in it's digital form or as a print that you can mail to them later - either created by your own photo printer or by a photo processing service.
*Graduations -preschool, high school, or college graduations offer dozens, if not hundreds of opportunities to capture a significant moment in someone's life. If the family members of the graduate aren't located in as good a location or don't have as good a camera as yourself - you'll have even greater opportunity at getting the shots they couldn't.
*Holiday Family Postcards -offer your services to families that want their picture taken and put on a postcard that they can send to their extended family and friends.
*Newborn photo service-parents of newborns are some of the busiest people in the world. Advertise your services on an on-call basis so that you can take informal snapshots for the growing family either before they leave the hospital, or after they get home. This way both parents and the child can be in more of the pictures all together, and the parents have one less thing to try and figure out.
