Brightness & Contrast

I am trying to calibrate my monitor using Adobe soft (yes, I know...).

The first step is to get brightness / contrast right, however using Adobe I get too dark and using some online tool I get too bright; I set it to what my eyes tell me which may be bad...

Anyway, without getting in the colors & composition etc., does the attached photo look like it has right brightness & contrast ? On my monitor, the photo is very well saturated in yellow areas (but doesn't look oversaturated), the center flower petals look bright but not blown out (well almost blown out in the center), the brown in flowers is going from dark blackish brown to almost black and the overall background is neither dark nor light. Well maybe a bit more on the dark side but very close to what I'd call medium brightness. What does it look like to you ?

looks good to me. I'm on spyder2 calibrated monitor

Thanks ! I am contemplating getting calibrator but read conflicting statements about its effectiveness.

if you do any printing it's a must! otherwise it's not really necessary and makes your images a little darker on screen.

Of course it's necessary. Well, if you share images at least. Otherwise it's worthless
