Although Internet is more widely used for all types of images and document transmission, facsimiles are still in practice. Faxes have some advantages and disadvantages over other methods of communication. A facsimile can easily produce pictures, factsheets, figures, graphics, etc. and can be transmitted in seconds.

The RAW image format offers some unique photographic capabilities. Normally, photos in the RAW format are considered professional and of the highest possible quality. RAW captures the data from the camera’s sensor: bit depth, color information, dynamic range, etc. Images are called “raw” because the data is not processed or edited, and the RAW image

Conversion of image folders involves more efforts than conversion of separate image files. Normally, each image folder refers to specific set of image files, and keeping the original folder structure is essential for converted images not to experience any image losses. Sometimes image folders are not so well organized, and it makes sense to re-organize

To prepare images for printing we normally offer our users the option to change the image dpi. But the question is: is there any specific image format that would provide the best print quality regardless of any other circumstances? Talking about image formats in general, each of them is designed for specific type of graphics

Practically none of the images are perfect when they come directly from the camera. Even professional photographers post-process their images to adjust their dpi, resize them, and convert them from one format to another depending on the purpose of their use. Not-so-experienced users have a choice between leaving things as they are, or practicing to

The RAW file format is known for its superb quality taking into account that all the resolution and data fr om the image sensor remains available for post-processing.

The CMYK color model defines the color space used for printing. It refers to the four inks used in most printers – cyan, magenta, yellow, and key (black).

Have you ever imagined life without color? We are so used to seeing colors that they have become something we take for granted. We prefer to go for bright colors on the day of ceremonies and functions to look good. Colors also stand as symbols like red is the symbol of fight and white is

When taking pictures, JPEG is the file format set as a default one for the vast majority of cameras. JPEG is not really an image format – it is a compression method that enables the users to save images with some quality loss. There is no way to completely avoid the quality loss, though some

Although the images may look great on the computer screen, they may appear distorted when printed out. For example, the image may look broader than normal, or narrower than normal. The picture may also turn out to be too pixilated which does not seem good looking. There is no connection between the size of the

Losing photos may be heartbreaking, even more than losing a document. Practically any documents can be duplicated, but memories saved in images cannot.

In true black-and-white images there are only two real shades – black and white, while grayscale images contain several shades of the gray color.

Online medical consultations, distance x-ray analysis, scientific research all require digital imaging. The 21st century is so computerized that it takes minutes to send questionable images to a distance specialist to get them reviewed. Directing medical questions to a reputable specialist in another part of the world gets easy if the inquiry is accompanied with

What do you normally do when you need to open a certain file and show the photo to someone, but fail to open it? An error message, such as “cannot open file type” may be very discouraging. Sometimes a certain file has no chance to be opened – there are specific data hidden behind its
