Digital Slr Cameras

BEST SLR DIGITAL CAMERA For 2009

By Chris Campbell

Digital SLR comes from digital single lens reflex, which is named this way because of the mirror that sits behind the lens of the camera and sends the light to the viewfinder.

The digital SLR's are designed in such a way that you can use a lot of different lenses, with different focal lengths. This versatility is the reason why digital SLR cameras are so popular among professionals. When you're using a camera that is not a SLR, you need to match the angle of the viewing lens with the angle of view. If you're doing short-range zoom or you have a fixed lens, then it's OK, but at different focal lengths it can be much more difficult. The SLR is better because the viewing and taking lens are the same.

While entry level digital SLR cameras don't always have Live View, advanced models usually do, and they let you compose the photos just like you do with a snapshot camera. The basic models will lock the mirror, and the prism will divert the image towards a sensor that is small. Then, instead of sending it to a capture sensor, it will be sent to the LCD screen, which can take down the performance a bit. If you're getting an older model you might need to focus on the image manually when you are in Live View, though contrast autofocus is available in newer digital cameras.

Digital SLR Camera Types

Digital SLR With Interchangeable-lens
These models are those considered as SLR's by most people. They're also the ones that we'll be talking about in this article. Just like the name says, in these SLR cameras you can change their lenses. This way you're able to switch from a supertelephoto lens to an ultra wide angle.
Examples: Basically, most digital SLR cameras that are sold today belong to this type.

Digital SLR With Fixed Lens
On these digital SLR's, the versatility is limited by the fact that you can't change the default lens. The mirror that bounces the light towards the viewfinder is nonmoving and semi-transparent in most of these models.
One example of a camera with fixed lens is the Olympus E-20N

Camera similar to SLR's
Cameras that look like digital SLR cameras are usually digicams that have either an optical finder or a small LCD. You can't consider them as digital SLR cameras since the mirror is missing, and the quality of the photos isn't even close to what you can do with a true SLR. Usually, this type of camera has a very long zoom, and another name for them is magazooms or ZLRs.

7 Smart Ways in Choosing the Best Digital Camera



By Pinky Mcbanon

Nowadays many people have the demand of having digital camera. Many other people would like to begin using this technology, but find the task of choosing an appropriate digital camera to be irresistible. So finding the best digital camera is not so easy. Here are 7 smart ways in choosing the best digital camera:


1) Computing Platform:
This is an obvious consideration but it is fast becoming less of an issue than it once was. Most current cameras can be interfaced with both Mac and Windows platforms.


2) Image Quality:
Image quality is a complex subject that includes exposure accuracy, color purity, optics, and image compression techniques.


3) Onboard Image Capacity: The amount of onboard image storage could be pretty important. There is generally a tradeoff between image capacity and image quality, so don't get too excited about high image capacity until you compare the amount of storage in relation to image resolution.


4) Reusable Memory Cards: Many cameras allow you to make your own decision about the memory/cost tradeoff by allowing you to store images on plug-in cards. This approach allows users to add as much or as little memory to the camera as they feel they need.


5) Exposure Versatility: digital cameras have the incapability to handle radically different lighting conditions. With film cameras, you can compensate for different lighting situations by using different types of film. With a digital camera, the camera's image sensor acts as the film, and it is not interchangeable.


6) Flash Capability: You have to also look for the availability and capabilities of a built-in flash. Key factors here are the range over which the flash will be useful, and the number of "modes" it has.


7) Self-Timer: A self-timer is simply a shutter delay that allows you to trigger the camera, and then run around to be included in the picture before the shutter snaps.

Nikon D40 Camera

Digital Camera Review

By William Redants

The Nikon D40 Camera is making the news. Nikon made the new D40 affordable and compact with the point-n-shoot features such as the SLR digital. It is suppose to follow the D50 series, yet it is more affordable. Some of the features are somewhat different, which makes some people wonder if Nikon is not compromising their D50 series.

Features - Let's take a look at the features offered with the Nikon D40 Camera. Instead of using old technology and creating a camera with mega pixel control, Nikon created this series with the viewfinder. Nikon also added the short shutter lag with the extremely short viewfinder blackout.
These significant features make the Nikon D40 Camera more appealing. Yet one of the most significantly difference is that you can no longer alter the exposure steps. There is a custom Auto ISO option. This option was available with the D80 series also.

Auto focus - The auto focus is designed solely for the AF-AF-S lens or I. Probably one of the biggest faults with this digital camera is that it doesn't have the internal focus drive engine. There isn't any mechanical focus drive pin either.
Some people feel that the CPU contact which allows the Auto Focus to work only with the AF-AF-S lens and I is a strike against the Nikon D40 Camera. These are lenses with built-in focus engines.
The standard lenses on the Nikkor 50mm F1.8D and the F1.4D are manual focus. This Nikon D40 Camera has a different mount than the D80. The D80 model has automatic focus drive pins, which are around seven o' clock position.
The chief features The chief features of the Nikon D40 Camera include the 6-mega pixel DX format CCD, Nikon Image processing engine, the innovative multi-cam530 with 3 areas of AF sensor and the ISO sensitivity range of 200 to 1600 in addition to HI 1. That is an equivalent of 3200.
Other chief features include the custom auto ISO that has selectable options including maximum ISO, or minimum shutter speed. The LCD is a no status and the new LCD monitor is a based status with setting screens.

The viewfinder is much bigger and there are in-camera retouching options. When you compare this camera to the D50 comprises.

How To Sell Your Pictures As Stock Photography

I love taking pictures. I just can't get enough. The more pictures I take the better I want to get. This also means that the more pictures I take; the more high quality equipment I want. It's an addiction. Many photography hobbyists have the same problem I do. If you don't want to pour all your money into your photography hobby, there is another option.

You can turn that photography hobby into a successful photography business. A great way to get started doing this is through stock photography. Businesses all over are looking for pictures to use in brochures, websites, advertisements, and more. These businesses will happily pay for your pictures rather than hire a photographer to take pictures for them. Here are some tips on how to get started on making money from your photography.

The first thing you need to do to start your stock photography business is to decide if you want to sell your pictures on micro or macro stock photography sites. Micro stock sites (ie. istock, dreamstime, and shutterstock) operate on the premise that if you offer photography at a low price, you'll get more sales (which they do). These sites sell pictures for as low as a dollar for small sizes, up to ten or twenty dollars for a large copy of your picture. They also offer other options like allowing prints, and exclusive license (they pay you a lot more but you can no longer sell the picture to anyone else). Photographers get a percentage of the sale, which can vary from 20 to 80 percent of the sale price. Many photographers don't like these sites because they sell photography for much less than they feel it's worth, but many small businesses rely on them for affordable stock pictures. The other option is macro stock photography (ie Alamy and MyLoupe).

You will probably sell A LOT fewer pictures on macro stock sites, but on these sites you make significantly more per picture, usually around $250 per photo (as opposed to the 60 cents I made off my first micro sale). Most of these sites will only accept pictures with over 6MP, but if your camera has fewer pixels, you can learn to upsize your photo in an editing program. While it is your own choice which route to take, many photographers start out on micro sites and then start moving their best pictures over to macro photography sites as their skills improve. You should note that some macro sites will not do business with photographers who sell their work on micro sites, so be sure to check their policies before uploading.

Once you've started uploading pictures, you need to remember not to stop. The more pictures you have online, the more sales you will make. Most sites have uploading limits and if you can, you should try to put up as many pictures as you are allowed. You should also put your pictures on as many sites as possible. Many people have their favorite stock site and only look for pictures there. This means you can put shots up on multiple sites; although many sites will guarantee you a higher percentage if you decide to upload a picture to their site exclusively. I would try not to overlap picture on macro and micro sites since someone probably wont pay $300 for a picture they can get for $1.

The next key to becoming a top seller is to take pictures with content that sells. Whatever you're subject is, you will almost assuredly sell more pictures if the background is a solid color. Black and white are the best, but any solid color will work. Generally people want a subject without a background. If the background is a solid color, it's much easier to remove with an editing program. If you want to know what subjects sell best, most sites have a section where you can see their most popular downloads.

Just remember to get inspiration from these photographs, don't copy them. If all else fails, you can never go wrong with pictures of people. You will need to get releases signed ahead of time for pictures of people with recognizable faces and also of recognizable property.

Hopefully these tips will help you get started making money with your photography. Just remember that, just like getting the perfect shot, starting your business takes time. You just need to work hard and not give up, no matter how slowly it starts. Many people started out slowly and are now making enough on stock photography sites to take photographs full time.
