Hi my name is Libby and I`m interested in any help I can get. I have a Pentax-Kr that i have been using since last summer. I always kept it in automode, now I would like to learn how to use the manual mode. I hope to improve the quality of my pictures, so any help would be greatly appreciated. When I take a picture outside in m-mode the picture comes out white and when I take one indoors it turns out fine. Can someone let me know how to fix the problem.
Thanks libby

Hi there, the lens I use on my Pentax is a Sigma 18-250. I`m attaching the white picture taken in manual mode and one taken in Auto mode.

i think what you need is in the manual on page 112 … the green button to set correct exposure values

or without the green button you can use this [ http://en.wikipedia.org/wiki/Sunny_16_rule ] to estimate the correct values for aperture and shutter speed

on your example the aperture was set (left?) on f4.5 - full open and shutter speed 1/50s, that is quite long for a day and lots of light, so these values must be changed accordingly, you can restrict the amount of light that gets it by closing the aperture, or shorting the time the shutter stays open … or both … in general you want fastest time when there is movement that you want to stop, and close the aperture when you want more depth-of-field (there should be more information about this in the manual as well) you can preview it by turning the on/off switch on Kr further beyond ON there is a picture of aperture blades on that switch for this (it'll close the aperture without taking picture, even if you do dof preview on display instead of the viewfinder that picture is not recorded

is it snow? all that white? if it is, then you might benefit from also adding a filter on your lens maybe UV and Circular Polariser(CPL) is quite handy to have if you take photos outside … just don't buy any of the extra cheap ones, they tend to make no to very little difference
