To quickly assess the difficulty of the text, read a short excerpt:
For an ordinary landscape an exposure of about three minutes will, on an average, be right. The lens used is supposed to take the public edifice above mentioned by the wet process in about ten seconds. We recollect instances where we gave an exposure of three minutes by the wet process, and this exposure was found requisite to obtain an impression ; in such instances as these, twenty minutes or half an hour will not be too long an exposure with tannin plates ; and yet we recollect very forcibly... that at one time, in the infancy of our acquaintance with the tannin process, we attempted to obtain pictures on tannin plates in those localities with an exposure of at most two minutes, and became utterly disgusted with tannin. An exposure of twenty minutes may appear egregiously long to portrait photographers ; but let them not be deterred from land- scape photography before they have balanced accounts. With the wet process in the field, each negative will re- quire, on an average, half an hour before it is finished, or in a condition to be carried from the field ; with the dry process, the impression can be made, on an average, in ten minutes.
