The grades and exposures will vary depending on the characteristics of the paper, enlarger and type of filtration. It has been time consuming because I have been learning how to do this and I made some silly mistakes along the way. The problems were with me - not the meter. However, it is worthwhile. For example, I was able to bang out 8 12 x 16 prints from different negatives yesterday in just over one hour - all without a single test strip, saving both time and paper. I have to 'tweak' multigrade IV as I am currently using the ISO-R settings recommended by Ilford. I reckon that start to finish, this will now take me about 45 minutes to an hour. Next, I have to calibrate MGIV Warmtone RC, which is around a stop slower than normal multigrade and not as contrasty. A full calibration should take around two hours I reckon and cost me about three or four sheets of 10x8 paper. I also have some other papers that I use from time to time, but for the moment they can wait... Don't let the calibration thing put you off. Based on my experience to date, the time invested in calibration is well worth it and it will pay dividends in the future both in terms of time and materials. It has also helped me to better understand the characteristics of photographic paper and how to interpret the information that appears on the data sheets. So it has been a valuable learning experience as well.
