What kind of a metering system does a Praktica have? I'm assuming it's centered weighted? Surely does not have matrix metering... hehehe.... still in looking at the histogram it's obvious that the image is all midtone....... no highlights and no blacks..... So your exposure was off. Here's what I think happened...... your meter (in fact all camera meters) are produced to find the normal exposure... normal being 18% grey..... now normal exposure is not necessarily the correct exposure..... So your meter read the sky.... ooopps too bright, it's not 18% grey.... and it gave you a reading that corresponded to what 18% is in essence a much faster shutter speed or aperture setting than what was really needed.... hence the dull underexposed sky.... This is also why so many snow pics look grey instead of white.... Doesn't matter if you're shooting digital, film, whatever.... meter off a grey card in the light that you are shooting in.... your meter will give you the correct exposure for 18% you can then be confident that all other tones from white to black will fall into place..... If you don't have a grey card...... meter off grey concrete, grass in open shade..... anything with in that tonal range and it will give you a proper reading....

I am, therefore I create.......
