5D Color Bars

The 5D seems to be more fussy than other Canon cameras when it comes to displaying jpeg files not actually shot on the camera.
These color bars were made by using the tool exiftool
to copy all the metadata from a genuine 5D jpeg into the color bars jpeg.
They also work on my old Canon 400D, the 7D, so probably work on the other canons. Get back to me if they don't.
After shooting loads on 5Ds, I've also made my own colour bars. Stick them on your CF card and have a go. I bought an old small CF card just for colour bars (on ebay).
The colour bars have four sections:
- 6 primary colours: magenta, red, yellow, green, cyan, blue. These are familiar colours so it should hopefully be possible to see any odd colour casts produced by the monitor.
- The next section down has some squares and numbers and is used to show the darkest and lightest shades the monitor can show detail in. The brightest shade (white) is 255 and darkest (black) is 0.
The values just above 0 should be very dark grey. The idea is to adjust the monitor brightness to see dark grey in a lower value as possible while still keeping the blacks nice and black. It might be shade value 10 before the the squares look very dark grey and not black.
On the white line, the brightest shades will probably blend into looking like maximum white (the 255 square). Adjust the contrast of the monitor to see darkening of the shades as close to the 255 square as possible while keeping the whites bright.
To summarise, adjust brightness and contrast to get differences in shade over a wider range as possible between shade 0 and 255.
- This section mixes full blue with a range of reds and greens. Switch on the monitor's BLUE ONLY control. Now adjust the monitor colour control (sometimes marked Chroma) to make this section all the same brightness. So it ends up looking like a uniform rectangle of all the same shade.
This sets the colour up correctly. Note, if you can't get it to neatly go to the same shade, the monitors colour gain settings may need adjusting.
Remember to switch off blue only when finished. If the monitor hasn't got a blue only button, then this part of the colour bars isn't used.
- The last section has some skin tone samples. An important colour and shown here to reveal any nasty colour casts from the monitor.
