Thank you so much Tim for your response.  I actually grew up in
Pittsburgh!  My father was a professor at the business school....

Anyhow, I actually have Adobe Lightroom - it came with my laptop. so that's
helpful I suppose.

I was thinking when I take the photos I would take them indoors  and set up
a black velvet backdrop we use for photos as the outdoors is generally too
sunny for good photos during the day (I'm in Hawaii). Do you think that
light ring would still be necessary? I suppose it couldn't hurt right?
Though keeping costs down is always good.

Another group suggested when processing to convert the image to grayscale
and then threshold it to examine the colors. Is the color correcting card
necessary  Because I see that it is rather expensive.

I'll try to get a sample photo and perhaps that would be helpful.

Thanks again.

Emily
