PSD native format: the weight of fame

Virtually all the software tools that designers use have their own formats to store projects, they also allow to use other standards for easy portability and usability of the software itself.

PSD is the native format of the application PhotoShop, and was designed with the objective of storing as much information as possible. The image documents saved in this format are, without doubt, the heaviest (document size in MB), but also the most editable documents. There are few voices calling for getting PSD format as a standard for image document. While so many are complaining about the problems of portability to other applications and storage caused by their excessive weight.

The core of the PSD is built in a short header that determines the image resolution and the color channels. Followed by three blocks of information called Colour Mode Data Block (data block color mode), Block Resources Images (image resource block), and Layer and Mask Information Block (block of information masks and layers) containing information about color space and duotone settings, channels, paths, layer opacity and blending modes respectively.

The PSD format was the first to provide support for layers, while the rest of the formats required flatting the image before storage. Currently, the layer support is a basic tool for graphic design and various formats are implementing this characteristic.

Adobe recommended PSD format for use in all applications that work with image documents, and integration with programs like Indesign is maximum, facilitating the work of the designers (this is easily demonstrated by placing a PSD with an EPS or JPEG in a model of Indesign) and improve the final quality.

In the picture below the first object is a PSD image and second is a JPEG. As can be seen, even using the default display settings, the first object image is much sharper and defined.

When working with an image stored on PSD layers can be edited to be displayed through the menu object and use the options on composition of layers.

Given the many advantages that this format provides is desirable to keep in PSD image any documents which have been edited, then according to tastes and needs is possible to attach and store it in another format, or use it as is and take advantage of the benefits additional features available. Storage problems incurred in its bulky size can be solved later with portable hard drives, tape drives, CD-ROM and DVD-ROM, or any other method (support) of storage available on the market.
