Digital Zoom Versus Optical Zoom

-->
http://activepics.blogspot.ca
Many digital cameras offer both digital and optical zoom.  These two often confuse the average camera buyer, until you know what you’re looking at.

 Optical zoom works much like the zoom lens on a 35 mm film camera. It changes the length of your camera’s lens and draws the subject closer to you.  The optical zoom keeps the quality of the picture. Digital zoom works differently. It simply takes the picture and crops it then enlarges the part that is left.  It causes the quality of the photo to be reduced, sometimes greatly.

What this means in terms of output is you may have a larger view of an object with the digital zoom, but chances are your image will become unfocused.  Details will become lost.  It is actually best to turn off the digital zoom feature of your camera if possible.  This will prevent you automatically zooming in too close as the digital zoom is often an extension of the optical.

There are a couple of things you can do if you want a closer view of a subject but want the quality of your picture to still be good.  Try moving in closer when you take the picture.  Often only a foot or two will do the trick.  If this isn’t possible, you can set your camera to take a picture at its highest file size.  This will result in a photo that can be cropped to include only your desired subject, yet allow for an image that is still clear.

Digital zoom has its place.  It can be used if the only destiny of your photo is the internet.  Photos online can be a much lower quality in the camera and still appear acceptable when sent through e-mail or posted on a web gallery.  If your goal is printing, however, seek a camera that has a greater optical zoom and turn off the digital zoom.  Your pictures will be better in the end, even if they are not as close up.

5 Easy Tips For Great Photo Shots

Award-Winning Business Class Phone Service
http://activepics.blogspot.ca
Today’s cameras make taking pictures a lot easier than the one’s of yesterday.  There is always room for improvement, however.  Use the following tips to help make your photos go from acceptable to great.

1. Always be aware of the background. You don’t want to find trees growing out of people’s heads or a passing vehicle to draw attention from your subject.  Sometimes moving your subject just a couple steps to either side can make all the difference.

2. Use available light. If your digital camera has an option to turn the flash off and it’s light enough outside to read a book then use the available light and turn the flash off. In general camera flashes are too harsh for human skin and make all of us look pale.  Indoors, where there isn’t enough daylight, place your subject by a window and use your fill flash feature.

3.  Aim your camera slightly down at the person’s face.  Also don’t shoot just face on to the person, try a little to the side, a three quarter view, so that you see more of their face. Remember camera higher looking down and a three quarter view, it will slim your subject.

4.   Remember your focus.  Get closer to your subject. Fill the frame with your subject and there will be no doubt as to what the picture is saying.

5. Never put your subject dead center.  Put your just slightly off center; not a lot just a little. When you’re shooting  groups of people, find the imaginary center line of your group and put that line just a bit off center in your view through your lens or screen.
Following these tips won’t turn you into an award-winning photographer today, but you will be on your way to better, more powerful photographs that others will comment on for years to come.

Let’s Get Digital: SLR Photography Basics


http://activepics.blogspot.ca
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: 

Prosumer models: 

Canon EOS 10D
Canon EOS Digital Rebel XT
Nikon D50 
Nikon D70s 
Pentax *ist DS

Professional Models:

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”!

UNDERWATER DIGITAL CAMERA: CAPTURING MOMENTS UNDERWATER


http://activepics.blogspot.ca
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.

Five Ways to Make Money Using Your Digital Camera


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. 

*Photo Novelty Items - take photographs of people that want the pictures of themselves of their loved ones imprinted on coffee mugs, mouse pads, key chains, tee-shirts, and other items. 

 *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.

How Many Mega-Pixels Do I Need?



http://activepics.blogspot.ca
One of the confusing things in choosing a digital camera is deciding how many mega-pixels you should look for.  The answer depends on what you plan on doing with the finished pictures.

First, you need to understand what a pixel is.  In terms of digital prints, a pixel simply means a dot of color that makes up the image.  A mega-pixel is equal to one million pixels.  The more mega-pixels a camera has, the greater the amount of information it records.

The easiest way to decide what to look for is to know what size prints you are likely to print from your camera.  A one mega-pixel camera is fine for those who don’t plan on printing photos but rather just post them on the internet.  A small print, say 4 x 6, will print acceptably from this camera.

A 2 mega-pixel camera will enable you to produce good quality 5 x 7 prints and fair quality 8 x 10 prints.  When you reach 4 mega-pixels you can print out excellent quality 8 x 10 prints and acceptable 11 x 17 prints and a 5 mega pixel camera will allow you to print out high quality 11 x 17 prints.

Most families find a camera in the 3.2 Mega-pixel range to be the best choice.  The quality of both 5 x & and 8 X 10 prints is very good yet the files on your computer are not so large you need worry about not having enough space.

Any camera over 5 mega-pixels is unnecessary for all but professionals in photography; even then, only those who have need for poster-size prints find that many mega-pixels worth the money.  Most freelance photographers find 4 or 5 mega-pixels to be sufficient for excellent-quality prints.

The choice is yours.  Look to what you plan on doing with your photos and then decide.  In most cases spending the money for increased optical zoom and lower mega-pixels is the best choice.

HOW TO FIND THE BEST DIGITAL CAMERA

affiliate_link
http://activepics.blogspot.ca
It seems that every month, if not every week, different manufacturers are coming up with the latest digital cameras to entice potential clients. And it's just not working for us!


After spending sizeable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lotsa pride in ourselves, when we pass by a new display - an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the "best digital camera." But then again, that doesn't last too long, after two months or so, there's another "best digital camera."


And so it confuses us. What makes a digital camera, the best digital camera?


Well, there are certain factors to consider when looking for the "best digital camera" for us.


MEGAPIXELS. One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.


LCD SIZE. The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.


ZOOM. Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.


MEMORY CARD. Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the xD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you're a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.


The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don't just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn't want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don't want to buy the latest point and shoot camera when you're serious about being a professional photographer. (Of course, you can use this for starters, but if you're not a novice photographer anymore, you wouldn't want to get this kind of camera.)


Actually, the best digital camera is the one that you will enjoy and use. Not the type that you'll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.
