Errors and Omissions Excepted...!

Or should that be 'accepted'! Last week we put up Scott's article on platinum printing, which seems to have been a considerable success - but I must make you aware of a miscalculation in the original article as published.

It has been corrected now, but Scott made mention of using shot glasses to create a series of contrast agents at specific percentages. In fact, instead of using 1, 2, 3 or 4 drops of distilled water with the 20% solution of NA2, it should have read 1, 3, 7 or 15 drops of distilled water to get the required 10%, 5%, 2.5% and 1.25%.

Thanks to scootermm over at APUG for spotting that one.
