When I create slideshows in iPhoto and Share/Export to iDVD to burn
disks for viewing on television screens, the quality of the imagery is
distinctly softer.

I'm not talking about originals from point-and-shoot photography. My
digital imagery is from a Nikon D70 DSLR and is extremely sharp, even
when blown up.

But when viewed on my Sony HD TV, using a Sony Blu-ray Disc Player,
it's not even close in sharpness.

Am I missing a setting somewhere? The D70 output is JPEG. I'm using
the latest iLife 08 upgrades.

Thanks,

What you're "missing" is that an NTSC DVD's resolution is (converted to
square pixels) 640x480 and that the colors are mapped onto the NTSC
color space, which is nowhere near so large as the original RGB space.
In fact, various wags have suggested that NTSC really stands for "Never
The Same Color". With the size reduction, YUV conversion, and the NTSC
conversion, a softening (or slight blurring) occurs.

Hi Jim
What you don't say is what size your HD TV is. I would guess it is
somewhat larger than the computer screen you are using. If that is the
case then they will always appear in softer focus no matter what you do
with them.

Dave -- you're right, my TV's a biggie, BUT the DVD slideshow on my 24"
iMac is also soft.
