A special note must be made for billboards and other materials that include photographs. The larger the size of the final format being intended for printing, the higher the resolution and image size of the original image should be. However, at no time should an image be artificially resized using resampling, generating a higher resolution image from a lower one. Resizing reduces the image quality the greater the difference between the initial and end image. It is better to leave resizing to the application that edits the intended document format. | A special note must be made for billboards and other materials that include photographs.

Photographs have a different colour and brightness level than it is possible to be handled by a printer and its inks or the printing medium. It is important to have very high quality, and particularly contrasting, vivid initial pictures from the camera. While editing images for higher contrast and a specific colour is advisable, such mitigations are only slight improvements that cannot fully compensate a poor initial picture. Ideally, a photo must be seen in the CMYK colour profile instead of the original RGB format, if your image editing software allows such on-the-fly simulations, to better gauge how suitable they are. Printing with similar means on smaller formats intermediate work is also very helpful. | Photographs have a different colour and brightness level than it is possible to be handled by a printer and its inks or the printing medium.

<code>''Desktop publishing is, generally, more flexible in content requirements but certain image formats and standard resolutions have to be considered depending on how demanding, and large, your material will be printed or how it will be transferred.''</code> | |||

Keep in mind that specific editing is required to make a standard photograph, as it may be received in JPEG format, to a picture containing transparency. Special processing is carried out in image editors to convert a standard image into one that has a transparency or ALPHA channel, as is usually called. Editing requires that the resulting format and your presentation application support transparency in PNG, TARGA and other formats, for a successful use in your presentation software. | Keep in mind that specific editing is required to make a standard photograph, as it may be received in JPEG format, to a picture containing transparency.

<code>''Although video production can cope with source materials from any resolution, it is advisable to standardize. Moreover, it is essential to standardize your video output format, and keep the same compression, resolution and frame-rate that is most suited to your display or web platform. Keep in consideration that your whole workflow from camera to display must support the requirements, having even one that is unable to do so wastes time or leads to unpleasant results''</code> | |||

These quick information sharing platforms have no ability for editing, meaning that cropping has to be particularly considered for photos. Ensuring that only the detail you want to present is visible requires severely editing a picture. Note that the final picture that is sent on a message is also heavily compressed, leading to much lower quality than the initial one. This is also the main reason photograph should never be shared on instant messengers and must be transferred in their original form, through other means, if they are later used for any publishing purposes. | These quick information sharing platforms have no ability for editing, meaning that cropping has to be particularly considered for photos.

<code>''Instant messaging platforms are never a substitute for traditional content sharing options. They are only advisable as preview options, since a lot of the original image quality is lost to reduce the storage demands on the platform, and you have no control over it.''</code> | |||

A good e-mail has to be designed with the intended recipient clearly considered. In most circumstance, this means that including large pictures is ill-advised. As a rule of thumb, most images should have a resolution below 1000 pixels on any axis and if multiple images are used, the final message size should be below 5 MB, particularly when directed at corporate e-mail. This ensures that just about any e-mail service will accept such messages. Services such as Yahoo! mail may accept a maximum size of 25 MB. This creates a rough guideline of the maximum size of photos you should incorporate. Messages with more than 5 photos are cumbersome to navigate as messages have few layout options that work on computers as well as mobile devices. | A good e-mail has to be designed with the intended recipient clearly considered.

<code>''The email system is not recommended for video sharing as content is neither transferred compactly or easy to modify. Most e-mail servers have different but always too low attachment size limits to allow decent quality videos to be transferred. Use other file sharing options for this purpose.''</code> | |||
