Subtitles of the Movie

Now as we have discussed in the previous lesson we saw the difference between print film and slide film, and how that can greatly affect your outcome. But now let us look more closely at the differences between fast slide film and slow slide film, if you understand what those terms mean. I am sure if you've gotten this far along in your photography hobby and you are pursuing doing manipulation in Photoshop, you understand the basics in photography and that being, the slower the film, the finer the grain, the faster the film, the more pronounced the grain is, no matter if it is slide or print film. But slide film, rating for rating, everything else being equal, has a much less pronounced grain signature than print film does. We have already seen it, we saw that in the last movie. But let us look at the difference between a fifty ISO Previa film and a four hundred ISO Previa film and you can see how, even with slide film, the grain is quite a bit different. First image of Yosemite valley at dawn, right after an early spring storm had come through and left the sprinkling of snow on the higher elevations, we got very nice, soft images here with the clouds that are hanging over the valley and wrapping around El Cap there, bit of clouds, little bit of color gradation in there and I will accentuate that later, not too much but just enough to make it a little bit more interesting in the lighting. But we are going to take this to a hundred percent magnification, and the grain-- you can see it but it is very, very low level of grain, not much here at all. Let me go to the solid areas of the photograph to really get the real feel for what our grain situation is. We look at dead center on this photograph, which is where it is going to be the worst, and you can see it is almost non-existent. It's a very good photograph, lots of detail, that is a very good result with fifty ISO Previa, Fuji Previa. The next shot is also of Yosemite valley, same day, later on in the day, very nice photograph, looks good, nice color saturation, not bad at all, but let us take a look. Look at a hundred percent magnification and you can see the difference. In fact, let us take this one back to a hundred percent magnification and look at the difference. You can see the difference between this, the fifty ISO speed film, and this, the four hundred ISO speed film, and when you go to print this, you are not going to have a whole lot of, especially if you only print it up to eight and a half by eleven, it is not going to be as pronounced, you probably will not notice the grain, but why have it there if you do not need it? I mean that is my kind of theory on things, so if you are going to shoot still life, landscapes, that sort of thing, use the slowest film you can get because you do have time to make a proper exposure on those slow films. If you are shooting kids and dogs and action and parties and all that, you need the four hundred because, number one, your lighting varies quite a bit on those active types of situations, and in order to stop that action, you need a fast shutter speed and often times you need a long depth of field, because your subjects are moving around. You don't have time to really focus like you normally would on a still life or on a landscape. So the faster speed films on action and fast-moving, often changing type scenarios; then on landscaping, you are using the slowest film you can lay your hands on, which is that fifty Previa Fuji, it's what I use all the time, great stuff.
