Hi Jeanette
I’m sure you’ll have heaps of fun exploring the various options and custom functions on the 20D. A word of warning though; whilst some only last for a session, others are persistent, remaining effective even when you turn off the camera! I’ve been caught out recently.
Whilst playing around some while ago, I selected the “Highlight Priority Setting” which makes the camera devote more of its dynamic range to the tones between mid grey and white. Today, I discovered that I had been unknowingly shooting with this setting for the last few days!
Also, my colour space seems to have reverted back from Adobe RGB to the default sRGB?
Hmm, I need to keep my wits about me and look out for the warning signs!
Apparently, when “Highlight Priority Setting” is selected, the ISO speed display in the viewfinder changes from say, 400 to 4oo as a subtle warning.
Cheers
Dennis
