    Hi Everyone. I have recently purchased a Canon EOS R100 camera, I take a lot of wildlife photos, but so far have only used the automatic sports setting, I now want to try the manual settings, I'm struggling.
    Shutter speed, if I set it to 1/2000 the picture starts going a little dark, then the higher I set it, it goes darker till eventually it's completely black.
    If I set it to 1/800, the picture starts going brighter, and the lower I set it, it goes brighter till you can't see anything.
    I must be doing something wrong, I've looked on many website tutorials, but just can't figure it out. I am definitely not an expert, has anyone got any ideas, can anyone please help. Thanks.

    Sounds normal to me. It all depends on your Aperture and ISO settings. I'm not an instructor so perhaps one of our more knowledgeable members can elaborate.

    Many thanks for your reply, I probably need to find an instructor, the ISO is 400, and f5.6.
    I've tried online instructions, seems a little difficult.
