    Thanks Bruce, it's well worth a punt. It won't compete with the high-end
    stuff where I lurk a lot
    I hope that buying a sude macro doesn't class as an upgrade ..... already.

  2. If you're photographing things like plants that don't move, it could be
    worth trying a series of shots with a cheapo macro lens, then combining
    them with focus stacking software like combineZM.

    Hadn't heard of Combine, but googled up their FAQ "CZM is too sharp, how can
    I reduce sharpness?" - I be happy to leave, as is.

    OT Irfanview reduce by pixel lengths i.e. 100 x 75. Is their a freebie out
    there, that reduces by MBytes?

  4. Perhaps I should have explained what it actually does a bit better. You
    take a series of photos, changing your focus a little for each one. Then
    combineZM cleverly adds all the sharp areas together, giving you one
    photo that's pin sharp from front to back. It's designed to solve
    problems of shallow depth of field, but it would be interesting to see
    what it can do with images from a cheap macro lens.

    Here's a test I made with it:
    This is one of about 10 images, as you see, only a narrow slice is in focus:

    Here's the combined image, showing far more of the subject in focus than
    would have been possible in a single shot:

    I agree with Bruce, that's good stuff. I assume a tripod is a must. Haven't
    ordered the cheap macro yet. The 350D arrived today. Weather miserable in
    the west, mainly indoor shoots.

    First impressions. The zoom and auto-focusing is a novelty, although I'm
    struggling to get to grips with manual focus lock. Colour definition in the
    reds and browns is quite precise, compared with my compact Fp1400. The
    display screen is much brighter, in fact the screen on the Finepix, was
    unusable in daylight.

    The only downer, is the camera case, it's a really, lightweight plastic and
    makes it feel a bit cheap. By contrast, my SLR film Ricoh was solid and my
    old Zenith's case was positively agricultural grade. I don't think the Canon
    would survive dropping onto a hard surface. Yet they've bonded a rubberised
    surface onto the waist of the zoom, for better grip. Would extending this to
    the vulnerable exposed parts, be too expensive?

    In general, I'm quite pleased with this upgrade. Friday's my day off, so
    I'll get familiar with most of the bells and whistles.

    If I can rummage around in the loft and locate my mini-tripod, the following
    could be a candidate for CombineZM and the cheap macro. In fact it could
    kick some serious butt, on the Carnivorous Plants forum :-

    The 4 cheapo lenses arrived this morning, together with the rain. The lenses
    are badged 'Sonia' - 1 Macro, 1 x 1, 1 x 2 and 1 x 4.

    However, there was sufficient light in the porch, not to need flash. The
    closest I could get to the target plant with my 28 - 90mm, was 20cm. With
    the macro I could get to 10cm. I found the mini-tripod, used manual focus
    with auto speed and stop.

    To my untrained eye, adding the 4 lenses, didn't show much loss of clarity.
    I'd welcome any comments. Meanwhile I'll bone up on Willy's CombineZM image
    sharpener link and wait for sunny weather.

    Edit :

    The distance from lens to subject was 10cm for the macro, all others were
    Speeds were 1/125 or 1/100 and the stops were 6.3 or 7.1

  11. Don't be put off by the less than friendly interface, it's
    straightforward enough once you get the hang of it. Remember that the
    set of photos need to be in order with the area in focus starting
    closest to the camera.
    That looks pretty good and definitely an ideal subject for trying the
    focus stacking software.

    Thanks Willy, I'll give that a try. Quick question on macro. What happens if
    I replace the cameras standard lense with an adapter tube. Can I get closer
    than the current 10cm?

    Ignore adapter tube query. I got a couple of helpful emails from the Joe,
    the macro seller : "Don't need an adapter, these are for 'point & shoot'
    cameras, that don't have a filter thread.

    However he did suggest adding the macro AND the extra lenses. He looked at
    the above pics and suggested getting more light onto the target and going
    for higher f numbers. By adding all 3 lenses to the standard lense, I can
    now get to within 4cm of the target, I could add the 1x lense as well.

    The following 2 (handheld) shots were taken with the pop-up flash. Canon
    warn you, with shots less than 1 metre, the barrel May obscure the subject.
    In this one, the subject is completely obscured and in the 2nd pic, it's
    The f numbers were still only around 5 and 6 ish.

    For occasional use these close-up lenses are great fun. As for lighting :
    it's probably not worth splashing out on a ring flash - unless you're a
    (Beware of Geeks bearing gifs). I'll wait for a sunny day in the greenhouse.
    Quite a few of the carnivorous plants there, have trapped some victims .....

    Update : what a difference a bit of sunshine makes. I managed to get the f
    stops up to around 10 ish - any higher and I get some severe camera shake.
    So I've ordered a new tripod, max 1460mm, also at £15. I don't have a bulb,
    so I guess I could use the delay, reduce shake further and maybe get higher
    f. Thanks for all your input, I will try the image sharpening tool - when I
    can get my head round the installation ...........

  15. Something you may like to test out is the effect of pushing up the ISO
    setting on the camera. I concluded that the D80 can be increased to
    800ISO before the grain became really noticeable. And if there's a risk
    of camera shake, a little extra grain is a good compromise as it never
    looks as bad as a blurry photo, IMO.
    At that price, it's unlikely to be rock solid, so you might find it
    worthwhile to hang a weight under the camera platform.
    Nice to see you're having fun.

    Thanks Willy, I'll read again thru the ISO section in the book of
    destructions, seems quick enough to change and I'll bang off a few shots on
    each subject at different settings - another big plus is the capacity of the
    battery versus the re-chargeable AA's in the old compact.

    Tripod hasn't arrived yet, agreed it is lightweight. Outdoors the anchor
    hook may get some useage.
