Image Processing Software

The National Gallery Scientific Department makes use of a variety of different pieces of images processing software to facilitate its image processing needs.

• VASARI Image Processing Software (VIPS): VIPS is a free image processing system. It aims to be about half-way between Photoshop and Excel. It is not designed for retouching photographs, but very handy for the many other imaging tasks that programs like Photoshop get used for. It is good with large images (images larger than the amount of RAM you have available), for working with colour and for research & development. Further details can be found at the VIPS webpage, which also contains a comprehensive beginers guide to the VIPS graphical user interface Nip2.
• GNU Image Manipulation Program (GIMP): GIMP is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages. Further details can be found at the GIMP webpage.
• Adobe Photoshop: Well known digital image processing tool. Further details can be found at the Photoshop webpage.
