AV News 183 - February 2011 Note: a word of caution, it's important not to use Photoshop CS4 downloads, you must always use downloads specific to Photoshop CS5. Also note that 64-bit TWAIN scanners are not officially supported in either 64-bit or 32-bit Photoshop. Use these at your own risk, although Adobe has found that the Canon PIXMA MP990 (64-bit) works well on both 32-bit and 64-bit versions for Mac OS 10.6. If you need to use a 64-bit TWAIN scanner on a Mac then Adobe recommend that you use this scanner and upgrade to Mac OS 10.6. To install the legacy TWAIN plug-in for Macintosh computers, drop the ///Optional plug-Ins/TWAINplug-in into the //Adobe Photoshop CS5/Plug-ins/Import-Export folder. The file entitled 'ReadMeCS5_Optional Plugin.PDF' really contains all the necessary information regarding what is included in your download and how to install each of the legacy items. Upon completion of this process, CS5 will recognise such equipment and thereby allow direct scanning into Photoshop using the import command. So you may ask is TWAIN an acronym and if so what is it an acronym of? According to official releases of TWAIN information the word TWAIN originates from Kipling's 'The Ballad of East and West' - 'and never the twain shall meet', reflecting the difficulty, of those early times of connecting scanners and personal computers in such manner that they could correctly talk to each other. Something that nowadays we take for granted, unless you've just upgraded to CS5! This word 'twain' was later up-cased to TWAIN to make it more distinctive. This up-casing misled people to believe that it was an acronym from computer jargon and this in turn led to a contest to come up with an expansion. None of the entries was officially selected. However the entry describing TWAIN as 'Technology Without An Interesting Name' stuck and unfortunately it continues to haunt both the standard and the Working Group to this day. It should be noted that the TWAIN Working Group does not maintain any specific scanner or digital camera drivers. You need to obtain the drivers for your devices from the scanner or digital camera vendor; these are usually provided on CD along with other pieces of software supplied when purchasing new equipment. If your scanner drivers were installed prior to CS5 then when you complete the simple pasting procedure described above your scanner will be recognised without re-installing any drivers. Most vendors including Nikon and Epson make available a back catalogue of drivers for older equipment at no charge from their official Websites, although with Nikon you are required to be a registered Nikon equipment owner to access the driver download section of their website.
