The X-rays I take are really dark on my film.

The X-rays I take are really dark on my film.
You must be sure where the dark films are being damaged. Most of the time it is not the machine, but a light leak (see below). If the processor developer is too warm, it will certainly cause dark radiographs. Check the temperature– it should be approximately 26°-27° C. (You can also check it quickly by putting your finger in the developer solution. If it is warm to the touch, it is probably overheated.) If the solution is too warm, unplug the heater, lift off the covers, and allow the solution to cool off. (You can pour in 200 to 300 Ml of fresh solution to cool it off faster). Some processors use a separate temperature sensor which controls activation of the solution heater. Overheating is usually due to a worn temperature sensor for those processors with a separate sensor. The machine that is taking the x-rays does not cause dark films. Dark films are only caused by the chemistry being too warm or light leaks. The slightest crack in the safelight filter will cause dark pan or ceph films (disregard periapical films, pan & ceph films are 200 times more sensitive to light). A very slight leak under or around the door (or into a daylight loader) will cause dark films. To test for light leaks, lay a fresh film out on the counter, place a coin on the film, wait a minute or two and then develop the film. If you can see the image of the coin, you have light leaks. If using a daylight loader, try using the processor in the dark. If this corrects the problem, your daylight loader leaks. To check for light leaks around a darkroom door, stand in the middle of the darkroom and turn all the lights off. Close your eyes for 60 seconds. Open your eyes and look for the source of light. Also, make certain you have a safelight with a GBX filter. Many times one may be tempted to use a red bulb but this is not a true safelight and could expose your films. Using a dedicated safelight with a low wattage bulb and separate GBX filter is essential to film quality. Last of all is the film itself. Make certain that your film is safely stored and is not expired. Always make certain to rotate your stock so that the oldest film is used first. When re-stocking film (and supplies in general), always put the newest supply behind the older stock on your shelf.
