With your broad experience of digital projectors, I thought I'd
see if you had any tips.
I have shown a lot of Powerpoint presentations connected to my
Macbook Pro and using a VGA connection.
I show images of my developmental pencil sketches as: RGB,
usually 300dpi or 150dpi, and JPEGS or TIFFS. I now use
Photoshop to deepen the drawing because some areas of the sketch
can be very light and delicate. Not all auditoriums or
classrooms are totally dark.
On occasion, these drawings are projected as the most clunky
bit-map-looking things, and to me, they just look awful. I've
had IT folks say it's the projector, and others tell me they
don't know, even after tweaking the aspect ratio for the
projector comfort zone. Doesn't work.
Is it totally the projector? or
Does anyone have any tips for planning for success? PDFs? (I
don't use those much in PPT). Grayscale ? CMYK?
Your experience is very much appreciated,
