Botany has taken a new twist in the chasing fame category. A famous space botanist has indicated that he believes a botanist will be the first to set foot on Mars. The reason for this is the need to have someone who understands microscopic microbes. This has unsettled the rockologists who felt they would be amongst the first to be chosen.

Plant life and the way in which plants can be cultivated and manipulated has proven to be both intriguing and interesting to many people for several years. Not only do plants have a beauty which we can all appreciate when looking at them, but they also play an extremely useful role as a resource for basic human necessities.

Botanical research is carried out in order to better and enhance the manufacture of such things as medications and foodstuffs and at the same time for preparing other products which are derived from plant extracts, discovering plant life on Mars would be an amazing discovery for the watching world. We do not only use plants to appeal to the eye by way of decorating our homes or improving the look of places such as parks and forests but also for the very functional solving of problems caused by pollution in our modern world as well.

Botany is the scientific study of plants so if this most natural form of beauty appeals to you and you feel you would like to take the subject seriously and you want to go to Mars, then maybe you should consider a career in Botany. Once you have decided that this is the chosen path for your future, you will be absolutely amazed when you find out just how many different species of plant there are in existence.

This will provide you with numerous opportunities in which you can specialize within your field of work and the wide ranging diversity of the subject will make it possible for people from all lifestyles to develop their knowledge of plant science. Whether you are male or female, Botany will provide you with a job full of satisfaction and enjoyment at the same time as allowing you the luxury of your work being of benefit to others. A visit to mars would certainly make you very famous.

Conservationist, ecologist, forester, plant explorer and taxonomist are just some of the many occupations within the field of Botany and work of this kind may involve travel abroad to exotic places in order for you to carry out your duties. A career as a plant physiologist, a plant biochemist, a molecular biologist or even the more complex field of a chemo taxonomist would be ideal for those who are more chemistry minded whilst for people with a background of mathematics, subjects such as biophysics, development botany, genetics, modeling or systems ecology are likely to be of interest. This would certainly qualify you for space travel!

Of course, as with any chosen career, how you conduct and feel about your work lies with you. What you actually get out of the job is determined by what you are willing to put in but in the line of Botany you can be sure that the hard work you will have to commit yourself to will be well rewarded when you have a career you really enjoy and from which you get a growing satisfaction each and every day. Not all Botanist will ever go to Mars but we are sure worldwide travel and a very interesting rewarding career awaits you.

The Botanists profession has fascinated Derek for many years. Remarkable discoveries are now sold in garden centers worldwide.

Although digital photography is a new and innovative way to take photos it is still founded on traditional photography and incorporates many of the same ideas. Both digital and traditional photography need a lens with which to focus the light as well as a shutter that lets the light into the camera. The big difference between traditional and digital photography is how the camera captures the image.

In traditional photography a film is used which needs to be developed inside of a darkroom with the use of chemicals. This development process results in a "negative" which you will then to print so that you can see the picture. Digital photography uses what is called an electronic sensor. It's this electronic sensor that catches the image of the picture. Millions of pixels make up the sensor, which then convert the light into a number. Instead of waiting for the photo to be developed a digital photo can be looked at almost immediately in the viewfinder of the camera.

Digital photographs use the number of pixels to determine the quality of the picture. Pixel count is often referred to as "resolution" and is measured in dimensions, such as 800x600. This is also known as the number of pixels per inch. A typical resolution for a computer monitor is 800x600. What this means is that the computer screen can display 800 pixels from one side to the other side and 600 pixels from the top of the display to the bottom. The total number of pixels would be 480,000. Digital photography uses resolutions that are higher than the computer monitor, often resulting in millions of pixels, or megapixels. If a digital camera has a resolution of 2048x1536 it has a total of 3.1 megapixels.

As previously mentioned, numbers represent the pixels. These numbers then determine the scale of colors that can be created. As an example, pictures that are black and white can be represented by megapixels that are only 8 bits long. As with binary arithmetic, an 8 bit number can then represent any decimal number from 0 to 256. This means that black and white pictures can have as many as 255 gray shades as well as black (0) and can also have white shades (256).

Larger numbers represent colors. For example, 16 bits per pixel can have a color scale of 65,536 different color shades while 24 bits per pixel can have over 16 million different types of colors. These days most digital cameras make use of 24 bits per pixel; however some professional cameras can have a color resolution that reaches 48 bits per pixel to create over 280 billion color shades.

The quality of a digital camera is affected by a few factors. Most times pixel resolution is considered to be one of the most important factors. You will want to choose the right pixel resolution for the size of pictures that you want to print. Remember that although the number of pixels in the photo won't change those images with bigger dimensions will have less pixels per inch. This will result in less detail in the picture as the size increases.

Photography labs will print photos that are 300 pixels per inch. This standard measure will let you calculate just how many megapixels your digital camera should come with. The largest print you can get from a two megapixel camera (that has 300 pixels per inch) is a 5.8"x3.8" picture. This is smaller than the standard 4"x6" picture. A digital camera that has four megapixels will be able to print photos up to a size of 8.2"x5.4" at about 300 pixels per inch.

You still have the ability to print larger photos. Keep in mind that photos which are printed at 200 pixels per inch will be less clear, however these photos will still be useable for many purposes. With this type of resolution you can get photo prints up to 8.7"x5.8" with a two megapixel camera. And with a four megapixel camera you'll be able to get pictures up to 12.2"x8.2".

Now that you have some understanding of the differences between classic photography and digital photography you can narrow down your search for buying a used camera.
