Photography As A Hobby – Understanding Its Different Components

Thursday, May 20th, 2010

Photography is a hobby that people will never get tired of. This is because it captures those moments that a human mind cannot store for long. It makes the scene immortal and helps keep memory of that which should be cherished.
If one wants to take up photography as a hobby or a profession, it is necessary to know about the accessories and elements of the camera in addition to knowing the technicalities of photography.
There are basically three components to a camera:
1. The lens or the optical element
2. The film or the chemical element
3. The camera body or the mechanical element
When these three collaborate, the image can be recorded.
From the traditional manual camera, technology has now brought us the digital cameras or the digicam. The digital camera has made photography accessible to the layman with its array of accessories and advanced features.
The difference between the analog camera and a digital camera is that in the latter, the pictures get stored in a digital format. This format allows the picture to be previewed before it is developed. It is also very convenient to print pictures using a digital camera.
The following are the present hot camera accessories:
Electronic flashes
For exposing the picture or scene on to the filmstrip, flashes are required. The shutter, on releasing, emits a large amount of light and exposes the film correctly at the time of illumination. An electric flash is especially useful for indoor photography when a picture needs to be taken in the dark.
Storage Devices
In those days, storage devices could not be removed. Nowadays, with the advent of the digital camera, there are many flash memory devices such as the memory stick, compact flash cards, and flash media cards that can be detached.
Batteries
Nowadays, digital cameras run on either disposable batteries or the rechargeable ones. The alkaline and lithium batteries constitute the non-rechargeable kind of batteries, while the NiCd and lead acid batteries constitute the rechargeable type.
Other accessories are the camera case or bag, straps and a tripod.
Knowledge about elements and accessories of a camera is not sufficient to practice photography. You must also know how to use these devices properly and should be able to maintain them for as long as possible. If you can do that, you will have an enjoyable experience while taking photographs.

The Different Types of Photograph Image Format in Which you Can Save your Data

Sunday, May 16th, 2010

With the use of digital cameras there are a few things that come into play when you’re taking your photographs and one of those things is the photograph image format you take your photographs in. For example, with the film cameras you had the option of using color positives, color negatives, black and white positives or black and white negatives.

This was a photograph image format that your photographic data was stored in. The same applies with digital cameras as well, and there is a photograph image format in which you can store your photographic data. It has nothing to do with positives or negatives this time, and everything to do with bits and bytes and how the little micro processor that reads the data from your memory card.

When you take a photograph, the information that the camera sees through the lens is stored on the memory card in a language that the computer understands.

For our purposes there are few different photograph image format that we can choose from, in which to store the details of our photographs, and we need to decide on what it is.

Having now hopefully, successfully navigated past that I can now go on to tell you that of the different types of photograph image format in which you can save your data, there are a few that most photographers use more often than not.

The RAW photograph image format has a great many advantages to be had, and these I have to say quite negate the disadvantages, if there are any. You know for a fact that nowadays memory cards are more and more inexpensive, allowing you to own more than one or two cards. Yes, sometimes RAW photograph image format files can be larger than the JPEG photograph image format, but the advantage of having a lossless file format far outweighs the fact that RAW photograph image format files are larger.

Whereas JPEG photograph image format files compress and therefore are prone to some loss of data, RAW photograph image format files aren’t prone to this loss of data.

But the biggest advantage as far as I’m concerned is the fact with RAW photograph image format files the image data that gets saved is the most basic data of all and when you transfer this to your computer, it makes it easier to work and change things around in your photograph using the photo editing software.
