    With this months theme erring towards macro photography, I tried a couple of shots out last night, and this was about the best. My camera (Canon A95) just does not seem able to get in as close as I would like unfortunately, tried some flowers and a lemon but struggled on the lemon to get the focus point right :(

    Anyway, here is one mildly sucessful one for you to rip to pieces :laugh:

    Can't seem to link it properly and have the thumbnail thing here :(

    Looking at the exif I agree with seany - f2.8 at 1/20th.

    You need a smaller aperture to get some depth of field and more light to speed up the shutter... even then macro shots still benefit from a tripod or at least steadying the camera against something solid. The more light the better.

    Don't expect to much of the focussing system - you may do better with manual focus and just move the camera distance to the subject.

    I was using the manual focus on the camera, but I must admit that it was a handheld shot, maybe when i eventually get my little tripod from the other house I will be able to do better then, with a longer exposure time, thus more light.

    Thanks for the pointers :smashin:

    The aperture size is the key - I believe the effect is less on a compact camera - but if you work at f2.8 you will have a shallow depth of field. Smaller aperture is better for more in focus depth and hence the need for lots of light if you want a fast shutter speed.

    You just need more light steve with macro on compacts because the closer the lens gets to the subject the less light's getting in. Even more so in doors

    Can only agree with Seany.

    This camera hasnt the best dynamic range or macro capabilities. I dont have a problem with burnt out highlights for the capture of good focus in the dark and midtones. In this instance the shadows need a bit more light or much slower exposure.
    You could reshoot using a tripod or add more light.
    Are you using the Spot Focus AE/AF method. Get closer if possible or use some zoom, but need more light if you zoom.

    Most compact camera use Contrast Detection as a focusing method. Often poor contrast equals poor focus. Hence a bit more light.

    I posted a couple of handheld macro shots to show the sort of focus and DOF you should get with a £200 camera.
    Obviously the DLSR brigade should be able to take fantastic shots with the better macro lenses.

    Thanks Longleyc.

    I was trying the extremes of the aperture control leaving it on it's lowest setting f2.8 as I wanted a fairly small focus point. I'm not sure what the focus setting was on though :(

    If I were to increase the aperture to something a bit higher I assume that this would lessen the amount of light needed but have a higher focus length? I'm still trying to unserstand all of this :laugh:

    I noticed when I zoomed in, the camera would not allow me to shoot at f2.8.

    You increase the aperture to something a bit LOWER f stop number.

    f2.8 may be as wide as your camera goes.

    If you make the aperture smaller - higher f stop number - you will need more light but have a greater depth of your subject in focus.

    when you zoom in the focal length increases. Focal length divided by Aperture size = the f stop number.

    Yep, f2.8 is the widest it goes.

    I get confused when people say increase it to a lower amount :confused: :laugh:

    Still learning or what!!! :rolleyes: :D

    If you are using an A95, then you need the following bits:

    Conversion Lens Adapter LA-DC52D [​IMG]

    and a Raynox DCR250 super macro lens

    With these and some practice, you should be able to get shots as good as this guy on Flickr who uses an A95 for macro work.

    Steve, I wouldn't of called it an idiots guide, but it's easier to grasp than someone trying to explain. I wish I had found something like it when I first started out.

    Like you I was always having trouble getting my head round smaller aperture means higher numbers. :thumbsup:

    Steve, have you got Photoshop or CS?
    After you got the focusing in order (OR set camera to Macro mode) you can add a bit more Focus (Sharpness really).
    Its my belief you can never have enough sharpness!
    There are various techniques.

    I often use all the ccd pixels, crop then sharpen for macro work. I use the High Pass filter, its less crude than Unsharp Masking.
    Also CS will allow you to use several images (bracketed exposures from your camera) to create a better dynamic range of exposure where its not possible to light the scene as you wish. Plus it makes for better looking shots.
