Yesterday, I was overdone with the teachers. I have nothing to do. Find the photo in the gallery and say the photometry.
Where do you start? Begin with latitude. The tolerance of the reversal film is smaller than that of the negative film and the digital camera. Different types of film have their own characteristics. But most of the time, the negative film can be slightly exposed because of its latitude, but also tolerate a little overexposure. That is, you can “accept more shade” of light in the case of “not overexposed” at high light, so that the shade can get more details.
However, the reversal film is different, and the reversal film is suitable for a slight loss of exposure to maintain its rich tone. In addition, it is very sensitive to high light, and it will die out if you don’t pay attention. So many times the scene of big light ratio is very difficult to do, because the tolerance is too small and it is difficult to take care of the highlights and shadows. However, the strong colors of people’s reversal film and the refreshment of direct viewing films can not stand.
Among them, we can see that the sky was dead and white, and it was overexposure. It used rvp50. The matrix metering used by the Nikon f50. The camera took care of the shadows under the sun and the parts of the left that were illuminated by the sun. Ignoring the sky, after all, it is really hard to take care of the big light. If you use a digital camera, you have to draw it and then pull up the dark part.
135 Frames don’t have to be so boring because the camera comes with metering. The need for large format in mechanical film is so particular. After all, is it more expensive?
So. How to expose the reversal film? How to measure light? How to take care of everything?
First of all, make sure the scene is suitable for reversal film, small light ratio, and reversal film can cope with the scene. Do not have a big backlight and then black and white scenes are particularly distinct. Then we have to calculate the specific exposure.
We see that the six places in the picture are relatively bright places. We know that reversal films are sensitive to light, so it’s best not to overexpose them. However, the brightness in these places is inconsistent. We need to know which are the subjects. Distinguish between primary and secondary.
This is taken with rb67. The old machine is too heavy for hahahaha. The medium format needs its own point-by-point measurement.
The hillside on the right and the place illuminated by the sun are the most important, then the lake. Once again, it is the cloud in the immediate vicinity, and then it is the distant clouds and the sky, and the mountains. This is the bright spot. Where we see the cloud on the upper left is overexposed. There is really no way.
Look at the darkness again:
The main parts of the shadows we need are the villages below, the forests on the upper right, and the hills on the left.
Then the problem is coming. If you only measure the light, the darkness will be very dark. If you want to embody the village below, the hillside will not look too bright. And we didn’t have time to manage so much. It was even less likely that we would count paper on the spot. We didn’t have the patience and time. After all, traveling, my girlfriend couldn’t wait too long to go shopping. It’s not right, like a single dog we don’t have a girlfriend to figure out about.
So good, first We determine the subject , is the hillside on the right, and the village below. And we know that reversal films can withstand dark places and cannot withstand high light. When you are urgent, you are facing The main highlights Measure, and then in order to take care of dark places (a little increase in point exposure, increase the amount of film can withstand tolerance), increase 0.3-0.5 file exposure.
This is not accurate. But there is no way, after all, there is not much idleness. This is 13 years or 14 years in Switzerland. At the time, there was no way to get there, but I saw it beautiful and shot it. Write casually, eat dinner
