| Our code may work with different models, but we have only tested the above listed models. If you want to use another photometer you can input the readings manually or consider writing a few lines of code in moncalib to support your photometer type. | Our code may work with different models, but we have only tested the above listed models.

| - | Note that there are some commercially available devices to calibrate monitor screens which create color profiling information (e.g. [[http://usa.gretagmacbethstore.com/index.cfm/act/Catalog.cfm/catalogid/1861/Subcategory/Eye-One%20Solutions/category/Eye-One/browse/null/MenuGroup/_Menu%20USA%20New/desc/Eye-One%20Display%202.htm|[5]]] [[http://www.xritephoto.com/product/optixxr/|[6]]] [[http://www.colorvision.com/|[7]]]. We have tested one of these called Spyder2Pro which allows you to linearize the monitor output but found that is not yet suitable for psychophysics purposes. The calibration program crashes when you use the default settings to linearize the monitor (an email to the tech support confirmed this is a bug in their software). Using advanced settings it worked but it could only test luminance at 5 output levels. The linearization that it achieved was not accurate enough when tested with the PR650 (it looked like they are doing some sort of spline fit of the points and the luminance as a function of monitor output level looked like a wavy line around the ideal). | + | Note that there are some commercially available devices to calibrate monitor screens which create color profiling information.
