Your time is precious. It 'annoying if you have an image too big, too small or not is open to receive.
And your customers, suppliers and friends hate you if you do.
In this short article will explain how to send the right size, in the proper format. And 'surprisingly quite simple once you know how.
Image formats and sizes at first sight seem very complicated, so give the people who send the wrong size or format. But onceTo understand a few basic principles, you can simply Each image based on size and send via email or upload to a website.
Begin with the end in mind
Take advice from Stephen Covey - Begin with the clear on your goal. What is the person to whom you send the image to go with it? It is only for them to look on your computer, or who need to print it? It makes a big difference (the reason is simple, and discover what itis in a minute). If the image is printed in large?
Pixels and DPI
The answer to the problem size has to deal with pixels. If you live in a bunker for the last five years, you have probably heard of them. You can also get an idea of what a pixel is: the smallest element of a digital image - a single square (rectangle, actually) from a single color.
The resolution of an image is expressed as PPI or pixels per inch. This is often confused with DPI(Dots Per Inch). Strictly speaking, it refers specifically only to the printers DPI, but in practice the terms are often used interchangeably.
Resolution essentially determined how big the image can be reproduced. This also depends on the output device (computer screen or printer). It 'important to understand the difference between the size and resolution. The best way to do this is with an example ...
To say that we have an image that is 300 pixels wide by 150 pixels high. This isSize or pixel size image. Pretty simple. But here's the hard part (note above):
The typical size computer screen is in pixels, 1024x768 pixels. The resolution is usually 75 PPI (which means that every square inch of screen space is 75 pixels wide and 75 pixels high).
So if we see in our 300 x 150 pixels, is four inches (10 cm) wide and two inches (5 cm) high. Fine so far. But what if you want to print, now thatPhotos?
different printing devices can print in different resolutions. But in general, a good image for the press, must have a minimum resolution of 200 ppi or, preferably, the 300th Any less than this, and begins to look big, fuzzy or pixilated. Or all three!
You may have heard of printers that can print at 1200 dpi or more, but this is the size of the image - there is no real need for a 1200 ppi image on the printer to send to separate.
Thus,can see that our 300 x 150 pixels is a size of about 1 inch (2.5 cm) and half an inch tall print. Big difference!
Now you're probably thinking: "Ok, enough with the explanations of how geeky I want my great big picture?"
Here are some guidelines, then:
On-Screen Display: 500-700 pixels height, width 700-900 pixels
Print - 200 to 300 ppi. So for a 4x6 "(10x15 cm) print, pixel dimensions should be 800 x 1200 for the smallest, or 1200 x 1800 tolarger. Of course, to a large print, you must increase the pixel dimensions accordingly.
The good news
Most image editing programs, all the calculations for you according to "resize. Here's how to resize images in common image editing programs:
In Photoshop (including Photoshop Elements), go to Image -> Resize -> Image Size, you can specify both the new size in pixels or inches or centimeters. NotRemember to use a resolution appropriate for your purpose (75 PPI for the screen display, 200-300 PPI set for release).
The procedure of Paint Shop Pro is very similar: Go to Image -> Resize, where you can scale both as a percentage of the original size, enter the new size in pixels, or specify the absolute size in cm or inches and PPI.
If you do not have one of these programs, you can also zoom in Windows Paint. Choose Image -> Stretch, then type the new size aspercentage of the original size.
It is also worth Irfanview, a free image viewer, which has for years. Supports all types of image formats (and then some), and includes batch processing (which lets you resize or otherwise edit multiple images in one step) and slide-show and a host of other features.
In Windows XP (and possibly other versions) you can also control the size of your image without opening it, the floatCursor to the file in Windows Explorer. A window will open soon with all the details.
Formats
OK, the last thing you think is the image format. Not only that substantially affect the file size (in bytes), but if other people can open it!
You may have noticed that the JPEG format (which stands for Joint Picture Experts Group, if you must know), often abbreviated to its Windows three-letter file extension,jpg.
Most likely, the images are in JPEG format if they come from a digital camera, although some digital cameras can capture images in TIFF or RAW (which are beyond the scope of this article).
There are some good reasons for the popularity of JPEG. The principal is great. A postcard-size, 300 dpi takes up about 6 MB in his "educated" at home. This is a great e-mail! The same image saved in JPEG format takes about a tenth of that when it is stored asJPEG quality at a reasonable level.
(The other reason is a popular JPEG format, because it is extremely broad support - as well as digital cameras, image editing or any viewing application can handle - which in turn ensures its popularity!)
So "compression" of photos, JPEGs take a fraction of the space that most other formats. There must be a catch, right? Well, yes and no. Let's do some 'deeper.
JPEG uses an algorithm (mathematical formula)to compress the image. And it does so mainly by "synthesis" part of the image with less detail in them. To do this, and achieve incredible compression ratios, it works, which "throws away" some of the data (technically known as lossy compression - as in contrast to the lossless compression of data. An example of a zip lossless compression algorithm).
Sound Well, 'throwing away, "not too good bit of the image, it does. Actually not so badas it seems. When you save an image in JPEG format, it varies with a range of high quality environment (as is shown introduced from program to program). As expected, the higher the quality the less compression is achieved, and vice versa. However, even at relatively high quality settings, the force of compression is still considerable, but the reduction (in the form of compression artifacts) is hardly noticeable.
By the way, if you need to send a photoFile that is greater than about 1 or 2 MB file transfer service such as yousendit.com or megaupload.com are a much more elegant to do so, as an e-mail. It saves both constipation your email and the recipient. Everything we do is done for the file to your computer and enter your e-mail and file transfer service the rest
I hope you are now ready to prove it! In summary:
1st Know your target
2nd image sizeadequate size in pixels, if necessary
3rd Save in JPEG format with a relatively high definition quality
Now go ahead and email and some pictures from all over the place!
