Why Shoot RAW Files?
There are many reasons to capture images as RAW files rather than JPEG files. However, it’s important to note that RAW image files require additional work to achieve the color balance you’re looking for, whereas JPEG files are color-balanced by the camera for you. JPEG files are also smaller than RAW image files, requiring less storage space.
The advantages to shooting RAW files are:
1. Increased bit depth allows for more color-correction “head room.” The JPEG format is limited to 8 bits per color channel. RAW images store 16 bits per channel, with 12 to 14 bits per channel of color information. Although it may sound confusing, this means you can do significantly more color correction without degrading the image or introducing color noise.
2. After the RAW file is decoded, you work with the most accurate and basic data about an image.
3.You control the white balance, color interpolation, and gamma correction aspects of the image during post-production rather than when shooting.
4. The image file isn’t compressed, as JPEG files are, which means that no image data is lost.
5. Most cameras are capable of and do shoot color outside the gamut range of JPEG (both Adobe RGB 1998 and sRGB), which means color clipping occurs when you shoot JPEG files. RAW files preserve the camera’s original image gamut, allowing Aperture to make image adjustments that take advantage of the full range of captured colors.
6. RAW files give you control of noise reduction (luminance and color separation) and sharpening after capture. JPEG noise reduction and sharpening are permanently applied to the image according to the settings on the camera.

f-stop
The photographer adjusts the opening of the aperture by setting the f-stop. An f-stop is a ratio of the focal length of the lens to the diameter of the opening of the aperture. For example, a 50 mm lens with an aperture opened up to a diameter of 12.5 mm results in an f-stop of f4 (50 ÷ 12.5 = 4). Therefore, the larger the numerical value of the f-stop, the smaller the opening of the aperture. The speed of a lens is determined by its largest f-stop value (smallest number). Thus, the larger the aperture, the faster the lens.
Definition: The number used to describe aperture size. A smaller number is a larger opening. The smaller number results in less light needed to expose the image and less depth of field (less in focus). A larger number results in more light needed to expose the image and more depth of field (more in focus).

Get As Many People as Possible to See Your Pictures.
A good article to look forward;
Get those millions to see your pictures instead of just thousands or just your circle of friends. Exposure is crucial. Not only will having more people see your pictures help you make more money, but it's also good for branding.
If people begin to see your pictures in more than one place they will begin to see that you are a big name photographer. Suddenly, the demand for your pictures will go up and people will be willing to spend more to have your images.
Years ago it would be tough to get a huge amount of people to see your pictures if you were just starting out, but with the internet it's not only possible, but it should be one of your main priorities to make your pictures viewable online.
No matter what kind of photography you want to get into, if you don't have some samples of your work online, you will be shutting out what could be a huge portion of your income.
Here are some ways you can use some free websites online to show off your pictures and your portfolio:
1. http://www.myphotofolio.com /
2. http://www.voodoochilli.net/
3. http://www.onetalentsource.com /
4. http://www.deviantart.com /
5. http://www.flickr.com /
You can also just put some of your best pictures together on a free hosted blog. The best free blogging services to use are:
1. Blogger.com
2. Wordpress.com
Or if you want you can use some social networking sites and use the power of Web 2.0. Here are some free sites you can join to advertise your photography for free and get some traffic to your portfolio:
1. http://squidoo.com
2. http://hubpages.com
3. http://www.zimbio.com /
4. http://www.wetpaint.com /
With all of the sites above you can add your photos and write something about them and your photography.
Then you can put the URL of your portfolio on your Facebook, Myspace, or Linkedin pages so your friends can see your work. You can also use that URL in your email and forum signatures for even more exposure.
But if you really really REALLY want people to see your pictures you have to put them where people who are LOOKING for pictures go. And where is that?
Every month there are MILLIONS of people who visit micro stock photography sites with money in hand, ready to buy photos.
You can upload your pictures to these sites and people can buy downloads of them. So after you put your pictures on there they can sell over and over again while you do nothing but rake in the dough. It's really quite simple and there are some making 6 digit figures with micro stock right now. Once you build up a nice size portfolio on the sites below it will not be impossible to be making at least an extra $1,000 a month, and the more you work at it you can make that $1,000 per week. Many give up before they see profits like this, but don't be like them=)
Here are some of the sites I am making money on right now, while at the same time getting more exposure for my photos.
1. www.Dreamstime.com
2. www.istockphoto.com
3. www.Fotolia.com
4. www.shutterstock.com
5. www.Bigstockphoto.com
I would recommend starting with dreamstime.com. They are fairly lenient on accepting your pictures and you can upload a bunch at one time to start selling them one download at a time. Fotolia is a great place to start too. There is one certain picture that I sell at least once a day on Fotolia and it makes me over $100 a month, every month, no matter what. In the next email I am going to show you my blueprint for making BIG money with micro stock photography so hold on. In the mean time you can get signed up at any of the micro stock sites above by clicking on the links provided.

RAW FILES
RAW files give you more latitude and possibilities in the post-capture editing phase. But don’t be lulled into thinking that RAW will save the day. Learn your camera, meter correctly, and capture with the same care you gave to film.Remember:“garbage in, garbage out” still applies in the digital world!
Even in those instances when JPEG is the better option for your shooting, always save the file as a TIFF before doing any editing.This will avoid further compression and data loss from your image.
TIFF is saved as a 16-bit file even though the sensor is only recording 12 bits of color information. The extra 4 bits of memory per pixel increases the file size dramatically because you’re now saving 32,768 levels for each pixel rather than the 4,096 recorded by the sensor—but you’re not getting more real information, just more file size.You get the same color advantage by saving as RAW and converting to 16-bit TIFF in the RAW converter.

Color Balance & White balance function.
In film photography, color balance can be done with colored filters. The filters are manually added in front of either the lens of the camera, the light source, the enlarging lens, or even different film types specific to the light source. With digital, photographers now use the white balance function of their cameras to maintain the correct colors from different light sources.
DON’T OPEN YOUR SHUTTER NEEDLESSLY!
Because of the nature of dSLR cameras and the electrical charge that powers the sensor, the sensor is extremely susceptible to dust. When small pieces of dust come into contact with a digital sensor, they create fuzzy darkspots on the image. Often these spots cannot be seen until the image is full screen on your camera monitor. Keep your lenses or caps on your camera at all times. Try to change lenses as quickly and carefully as possible. If your sensor becomes dirty, follow the manufacturer’s recommendations on cleaning. It is difficult and expensive to repair a damaged sensor.
