so i set up the Spyder3 today. It set the brightness to about 191, sid the ambient light in my room was veryu high/. The monitor is quit bright now, iMac 21.5" and i tried a sample print again. Still coming out quit a bit darker than screen. Do i need to adjust the monitor brightness now to a lower out put or will that effect my calibrartion done,
I'm quite confused now as it had been printing out close to monitor for a while. Maybe i should do a Walmart or Henrys kiosk print as a double check Dave On Fri, Sep 2, 2016 at 9:46 PM, Godfrey DiGiorgi <[email protected]> wrote: >> On Sep 2, 2016, at 10:53 AM, David J Brooks <[email protected]> wrote: >> >> I have purchased a new in box Spyderpro 3 as it will work with 10.6.8, >> supposedly.
