Variable contrast

When there is no replication and the design is sufficiently large either three normal plots can be constructed, one for the design variable contrasts, one for the environmental variable contrasts, and one for the... 

As was discussed with arrangement (I), it is possible to split the two degrees of freedom for Temperature and Humidity into linear and quadratic contrasts and to construct a normal probability plot for the environmental variable contrasts. This would reveal important effects due to the linear components of both Temperature and Humidity. A normal plot for the design contrasts would indicate that there appears to be a real effect due to A. The analysis of the design x environment interactions is obtained by pooling together higher-order interactions to obtain an... 

Variable contrast control produces higher signal/noise ratio... 

Unmatched tonal separation, especially in highlights, even when printed on variable-contrast paper. 

Change your variable contrast filter to a higher or lower number. 

Here are the steps to accomplish the most efficient and best print results for printing on variable contrast paper ... 

Stop the lens down one stop. If you are using graded paper choose grade 1 or 2. If you are using variable contrast paper use filter VA or 2. 

The difficult task of expressing our everyday experiences of color matching often cannot be adequately defined in a color space. Extended light sources, flicker, stroboscopic effects, variable contrast backgrounds and surrounds, matte surfaces, and polished top layers such as a leaf (107) and others cannot be properly defined mathematically. Calculations that involve such parameters are only approximations of the situations they represent. Try to imagine how dull a scene would be if you only perceived instrument measured color information.
