Channel confusion (perhaps) when opening a TIFF

Stephen Hart
I received a 32-bit uncompressed TIFF from Photoshop 7.0 (probably) on an
Intel-based Mac which opens correctly in Photoshop 7.0 under Windows XP but
which opens incorrectly in ImageJ 1.42l under Windows XP. It looks like the
green channel is opening as blue, the blue as green, and perhaps the alpha
as red.

ImageMagick identifies the file as follows [I left out lines which seem
irrelevant to color issues]...
  Format: TIFF (Tagged Image File Format)
  Class: DirectClass
  Geometry: 800x600+0+0
  Resolution: 72x72
  Type: TrueColorMatte
  Base type: TrueColor
  Endianess: MSB
  Colorspace: RGB
  Depth: 8-bit
  Channel depth:
    red: 8-bit
    green: 8-bit
    blue: 8-bit
    alpha: 8-bit
  Alpha: none   #00000000
  Rendering intent: Undefined
  Interlace: None
  Background color: white
  Border color: rgba(223,223,223,1)
  Matte color: grey74
  Transparent color: none
  Page geometry: 800x600+0+0
  Iterations: 0
  Compression: None
  Properties:
    tiff:alpha: unassociated
    tiff:rows-per-strip: 2
    tiff:software: Adobe Photoshop 7.0
  Profiles:
    Profile-8bim: 3046 bytes
    Profile-xmp: 4649 bytes
  Tainted: False

Is this an ImageJ issue? Or did I do something stupid?
