A Computer For Digital Photography

First of all, what does a computer do? In our world today the word compute |kəmˈpyoōt| means to make a calculation, especially using a computer: modern circuitry can compute faster than any chess player. So is a photographic image made by a calculation of number values? Yes, to some extent with a digital camera. But graphics, an image on-screen was a side effect of computing, a part of the in and out communication with a computer. It was not what the computer did but how it communicated its answers after the question were typed into a computer with a keyboard. A monitor was just a convenient way to make a computer respond so its output could be read by human eyes.

In the 80’s when personal computers began to be common all they had was a keyboard and a monochrome display that reproduced text and numbers. During the same period Apple computers were used to begin the desktop publishing revolution, probably the first popular use of computers for graphic purposes. Today with computers reproducing all kinds of media and being used as a communications and entertainment device, a computer’s original function and an understanding of how they worked has been lost to all but the few who used computers over a generation ago. We all take them for granted. One of the earliest and most common uses of a PC was to run a cash register in a store.

Today when a photographer begins shopping for a computer there aren’t any that are designated as digital photography models. Nearly all personal computer today can deal with photographic images to some middling effect, and none are attributed with any special photographic abilities. Maybe that is just as well because a photographer shopping for a computer maybe should be looking for the one key part of a computer system that is “graphic”, and that is its display. LCD displays that are designed and made for graphics computing are few, rare and relatively expensive models.

So, a photographer looking for a computer to do digital photography should first select the best graphics LCD display that can be afforded, and it may cost more than you need to pay for the rest of the computer system. Then get a personal computer to run the display. It can be quite modest because digital photography processing and editing involves very little “computing” because photos are not the result of a calculation. The only factors in the computer that are important to photography are a good quality 2D video (card), and the addition of as much RAM as can be afforded.

This may sound like a radical idea from a computer geek’s perspective, but it works for me and many other photographers. What few people realize is that there are hundreds of millions of computers used in offices, institutions and now most homes have a computer or two. But the number of people who are serious digital photography users can be counted in the thousands. That is a radically small part of the computer market, too small to even be considered a niche market. There aren’t any computers made especially for digital photography, so do it yourself.

Which LCD displays should a photographer shop for. Well I have written about the few I can recommend in past articles in Shutterbug, as well as mentioned in my Digital Help column and this blog. But I am currently considering adding another make and model, but also dropping one model from my list. So keep tuned in, that update will appear soon.

Even though you may be able to make money online regularly, keeping physical records of your work and earnings is still important. Print out the data from a well-maintained spreadsheet or keep a notebook by your computer. Keep accurate and up to date information that you will later need for tax purposes, to verify income or just for your own purposes. Data can be lost all too easily online. get cash for surveys

One great way to lose weight is to eat a little slower. As you begin to digest food, you will begin to feel full. It typically takes from 20-30 minutes after beginning your meal for your brain to receive the chemical signals showing that your body is satiated. To ensure you allow proper time between bites, take a bite and set your fork down. Eventually, you will start feeling full. proactol reviews

You should not consider going to college unless you have a good idea of the kind of career you want or at least have a general idea. Meet with a career counselor to find out more about your different options and take the time to do some research about different schools and programs. magnetic messaging

Usually a successful website has only a few typefaces which are of a similar style, instead of using a range of typefaces. Preferably a website should use sans serif or serif typefaces, not a combination of the two. Typography in websites should also be careful the amount of typefaces used, good design will incorporate a few similar typefaces rather than a range of type faces. Thanks.

Many camera phones and most digital cameras use memory cards having flash memory to store image data. The majority of cards for separate cameras are SD format; many are CompactFlash and the other formats are rare. XQD card format is the latest form of storage medium. injury attorneys
