Well IMHO it's a BUG in the sense that THIS type of files (Photoshop 
duuuh ....) should definitely be not included in
    tx_dam_types.php

(even if the majority of coders probably prefer ASCII-art [optionally 
animated ...] with media type: TEXT ;-)

Options would be:
   'psd'	=> 'image/photoshop',
   'psd'	=> 'image/x-photoshop',

& yes pls. add it in the bugtracker;
(wiser chapse/sses than me might decide on +/- x)

 From a documentation point of view NO, this should IMHO not be 
recommended. reasoning: The TYPO3-Developer should better use Georg's / 
Francois's advice on changing it via the TCA, that is via an Extensions;
reasoning: File-Extensions / MIME and Media-Types dont change that often 
and are "somewhat" standardized. So it should IMHO rather NOT be the 
task of an editor (or any person accidently owning BE-admin-rights) to 
change those.

class.tx_dam.php

	/**
	 * Register a file type
	 * This extends or overwrite the internal list of mime types which is 
used to detect a media type and a file type.
	function register_fileType ($fileExtension, $mimeType, $mediaType='') {


BTW-1: I thought, I've even also seen an example in EXT:dam_demo however 
cant find it by now; (never been there there?)

BTW-2: This "T3_VAR" "feels" extremely outdated; together with Francois 
I'd vote for putting it into $TYPO3_CONF_VARS;

PS at Uschi: Thanks for your excellent efforts on documentation so far.
