Angles of view with different lenses..

The diagram shows angle of view or angle of acceptance.

I have been looking back through my college notes and came across this series of pictures. I used the colour film you find in the pound/ budget shops. I have had no problems with the way the film has performed.

These pictures show how much of the view in front of the lens is depicted at the negative. As the focal length of the lens increases the angle of view reduces but the object size gets bigger. Therefore as you go up the focal range so the depth of field lessens.

Ilfords new darkroom paper.

The old Multigrade 4 FB.

Ilford have launched an upgrade to its popular Multigrade 4 FB darkroom papers called Multigrade FB classic suggesting that this is the best light sensitive paper they have produced so far. If you judge it on sales alone and the fact it has sold out you maybe right or they could have simply under estimated it's popularity. It comes in gloss and matt surfaces offering greater sharpness, shorter development times and improved Max D – could this mean less time in the wash? Available at all the usual sizes. The classic paper has a white base tint, neutral image colour, good mid tone range and deep blacks. It has also been made more sensitive to traditional toning techniques but then I didn't find the original that difficult, even with toning developers. As part of the changes a cool tone FB paper has been introduced to complement the warm tone FB papers. This has crisp whites and nicely separated midtones. One of the surprising things about this paper is that Ilford has kept the price of the paper at multigrade 4 FB prices so far.
