Beginner - What am I doing wrong? C+C

    Hi

    There are two pics below. Completely different but lots and lots of errors etc. in both.

    Both pics were shot using a 350D.The horse pic was a handheld shot at Tv-1/1000, Av-6.3, ISO-800, Focal-263mm with a Sigma 70-300 APO Macro lens.
    The waterfall pic was a tripod shot at Tv-1, Av-36, ISO-100, Focal-55mm with a Canon 18-55mm kit lens.

    So, what am I doing wrong? The horse one probably isn't too bad, especially for a beginner :) but the composition isn't great. What else could I do to improve it? I cropped it to remove a pallet against the ditch and did a bit of colour adjustment but thats it.

    I'm more concerned about the waterfall pic though. I'm reasonably happy with the rocks on the left and everytihing south of that. However north of that is a disaster. The waterfall is seriously over exposed (I think) and no matter what I did I couldn't get it to expose correctly. Well I could, but only if the shutter speed was increased and the Av reduced but then I couldn't get the smooth wavy water at the bottom.

    Is it the lens I was using? At the 1 second shutter speed the max aperture I could get was 36. Is it me doing something wrong? What could I have done to try and get what I am looking for or is it just impossible to do with my equipment and/or serious serious photo shopping?

    Any help would be greatly appreciated.

    Ballyman,

    You are correct that your waterfall shot is overexposed.

    If you want that blurred water effect then you are correct to use a small aperture (large f number). Now your autoexposure system is giving you an overexposed image so you now need to apply some -ve exposure compensation to stop this from happening which will have the effect on shortening exposure times. However, you will now start to lose that water effect.

    Now assuming you are at minium ISO and minimum aperture, the only way to get a longer exposure is to either shoot when there is less light (e.g at the end of an overcast day) or to use a neutral density filter over your lens.

    I hope that helps a bit. It is very important in waterfall shots that the brightest whitewater is not blown out as it will stand out like a sore thumb.

    Cheers Andy, you're right. I was at minimum ISO and Aperture.

    I'll give it a go again this evening or tomorrow when it's a little darker. Can you recommend any filter that I could get also?

    A simple 3 stop neutral density filter is quite useful for these applications.
