Anonymous users2024-02-05This is ISO, or sensitivity, and the higher the ISO value, the stronger the sensitivity of the material. In layman's terms, the higher the sensitivity, the coarser the particles of the negative, and the worse the effect after magnification.

Anonymous users2024-02-04135 is a centimeter wide and 120 is 6 centimeters wide. Therefore, the 120 film will be about 6 times clearer than the 135 Because most of the 135 film itself will not be too clear (for digital machines), so the 120 will appear better and more suitable for developing larger **

At the moment of closing, the transistor is turned on, the C pole has a current through, L1 and L2 form a step-up transformer, and the L2 coil has a high-voltage pulse output. However, the switch cannot be closed continuously, and if it is closed continuously, there will be no high-voltage output. It should be constantly turned on, off, on, off, on, off.
36 issues changed for 15 issues, and 12 issues remain? I don't know how to do it.
