Tungsten illumination requires correction values that increase blue and decrease red, while the reverse is true for daylight illumination.Īchieving proper color balance in images obtained with a digital camera system coupled to an optical microscope depends upon a number of factors, beginning with establishment of correct illumination conditions and precise microscope optical alignment, and culminating in the image capture stage. Note that different color correction values are employed by the algorithm to balance the tonal quality of the image, depending on the illumination color temperature. Applying white balance algorithms to images captured with either the tungsten or daylight balanced illumination eliminates shading due to color temperature effects, as illustrated in Figure 1(b). Inserting a color conversion filter into the optical pathway renders the image with a slight bluish tinge in the eyepieces, and corresponding digital images captured without white balance correction maintain or amplify this color shift ( Figure 1(c)). If the digital camera white balance function is not activated and applied to the current microscope configuration, images captured under these conditions also appear to have an overall yellow cast ( Figure 1(a)). Without a color conversion filter, the DIC specimen in Figure 1 appears neutral gray, but exhibits an obvious global yellow hue, characteristic of incandescent illumination, when observed through the microscope eyepieces. In the eyepieces, the cell culture appears neutral gray in color when the Nomarski prism is adjusted to achieve the optical path difference illustrated in Figure 1, and a color conversion filter is added to the light path to raise the color temperature of the tungsten-halogen lamp from 3200K to approximately 5500K (daylight value).

The specimen is a monolayer culture of adherent Indian Muntjac deer skin fibroblast cells viewed in differential interference contrast ( DIC) at relatively low (one-twentieth of a wavelength) bias retardation.

Presented in Figure 1 are a series of digital images recorded of the same microscope viewfield under varying conditions of illumination color temperature. One factor contributing to this discrepancy is that, during imaging, a considerable accommodation of the human visual system to variations in imaging conditions occurs subconsciously, and color rendition problems are usually not realized until an image is recorded and the static version evaluated, often in a different viewing environment.

This is an interesting page regarding lut profiles and a profile editor.When a captured digital image is critically compared to the image observed through the microscope eyepieces or viewed live on a computer monitor, color variations are often quite striking, and attempts to reconcile differences between the two can be frustrating. If you can adjust your image as needed in Photoshop, then you could create a hald image, apply the same processing to it in Photoshop, then use that result with -hald-clut to apply it to any image in IM. For the lut approach see and for the color-matrix approach see Note some profiles use a color-matrix approach and others use a lut approach (such as colorizing a gradient and applying with -clut).

I suspect you really need to use -color-matrix in rgb to be able to fine tune what you want.

tint will only colorize a grayscale image in the midtone range, -colorize will colorize a grayscale image across the tonal range and +level-colors black,some color will help in the mid to highlight range There are standard profiles, such as CMYK.icc and sRGB.icc. I am not an expert on profiles, but see -profile for adding (and removing profiles).
