closeup digital photos - ??
I'm no shutterbug. I'm using a digital camera that cost about $200. It
isn't a fancy Nikon which allows you to swap lenses or anything remotely like that. Still, it ought to be able to take a closeup of something about the size of a golf ball. I simply can't make it shoot anything clear. It has a zoom button. It has "macro mode". It has autofocus, and I know about putting something like a playing card at the right distance and holding the button halfway down to hold the autofocus and then shooting the object. I get pictures that are semi-usable but nothing at all that can really be said to be in focus. I believe I've tried all 4 permutations of zoom and macro mode. Is it me, or the camera? If me, what should I do differently? If it's the camera, what other camera works better? BTW, what I'm shooting are details of my die filer for the die filer Web page I'm building. I know there is probably a more specifically correct NG but I'm real used to this one and we have many knowledgeable regulars. Grant Erwin Kirkland, Washington |

Might be the camera. I've got an Olympus 340R that shoots macro at about 4"
and pictures come out real well. Sometimes you have to turn the flash off to prevent wash-out. -- Gary Brady Austin, TX www.powdercoatoven.4t.com "Grant Erwin" wrote in message ... I'm no shutterbug.

Some cameras, although they include a "macro mode", just aren't good at macro-photography. Usually the limitation is in how close you can get to the subject you're trying to photograph, and this is a limitation in the lens system in the camera. If you have a standard 50MM lens from a 35MM film camera you can try placing it in front of your digi camera and shooting through it. The 50mm lens acts as a (super) "macro adapter". Use manual focus in this case. |

Grant Erwin Kirkland, Washington You probably need higher resolution (more megapixals) to get the detail you want. To get the most from what you have, use lots of light and a tripod to keep the camera steadier. The more light available, the smaller the aperature and hence more depth of field. fred |

Turn on macro mode and turn off the flash. Shine some bright but diffused
light at the object. Then use a tripod or somehow hold the camera still (for example by piling up some books and resting the camera against them). "Grant Erwin" wrote in message ...

I am also new to didigal cameras but I have found this works fine: Just get
the object in the viewfinder and snap the picture. When I go to edit the picture is so huge it won't fit on the screen anyway, I just crop the section I want and it comes out as a closeup. I am guessing that this has to do with resolution... the more you have the bigger the picture comes out, at least that holds true for me. LB "Grant Erwin" wrote in message ... I'm no shutterbug.

Try reading the instruction book. For example, on my Sony, I have to have the
zoom in wide angle mode for the macro to work correctly. Sometimes trying to use macro need you need to use the rear screen instead of the viewfinder. You should be able to judge for accruate focusing then. Earle Rich Mont Vernon, NH Teaching another digital photo class in a couple of weeks. |

It to, in effect, "force" your camera to autofocus on _your_ object, cut a hole in some junk flat stuff (eg: corrugated cardboard) that very nearly 'fits' your object outer edges, then suspend, or place, your object "halfway into" that surface, so half of it is above, and the other half below, the smooth surface. the camera will be left "no choice" but to focus correctly. admittedly not a 'dream solution', but one that works. to 'class it up' a bit, cover the cardboard with a clean bath towel... or drop your object into a soft feather pillow, or surround it with planks at the same level, etc. my camera has the 'option' to hold a 'forced focus' but I'd have to wade thru 90 layers of menus (and six hours of reading) to accomplish it - this is far simpler :-) dave -- to reply, please remove the "weird stuff" from my email address. thanks. |

I get pictures that are semi-usable but nothing at all that can really be said to be in focus. I believe I've tried all 4 permutations of zoom and macro mode. One thing which I have found is that the autofocus on my older digital (A Nikon CoolPix 950) is *very* slow in macro mode -- but is speeded up significantly by taking a small high-intensity lamp (Tensor or similar) and using it to pre-illuminate the object to be photographed. I've now moved to a Nikon D70 (interchangeable lenses that also fit the film cameras), and the zoom lens which I am using (28-104 mm) has a macro mode which only can be enabled at 50 mm or longer, but it does a much quicker job of focusing in macro mode (or normal mode, for that matter) than the CP 950. My wife now uses the CP 950. While you've gotten lots of suggestions (of which I consider the best to be more illumination and put the camera on a tripod or some other form of source of stability), I think that you might get more finely focused (so to speak) advice if you told us what the camera make and model are -- so those with experience with that particular model can offer advice from their own experience. After all -- it *might* be that the macro mode on the camera is simply lousy. Is it me, or the camera? If me, what should I do differently? If it's the camera, what other camera works better? The CoolPix 950 (no longer in production) works down to 0.8" distance -- so it can make images on its focusing screen larger than the object being focused. It also quenches the flash when enough light has arrived at the CCD sensor so you don't get over-exposed. I have a tiny table-top tripod for the 950 (which I also sometimes use for microphones), which might be just what you need with your camera. A major problem with low light close up photos in particular is that if you aren't *very* careful to press the shutter relase slowly and gently, you will jostle the camera just at the moment that the image is being formed. BTW, what I'm shooting are details of my die filer for the die filer Web page I'm building. I know there is probably a more specifically correct NG but I'm real used to this one and we have many knowledgeable regulars. Well ... if you're shooting a die filer, I think that this qualifies. :-) But there is rec.photo.digital which might give a lot more advice, with more experience with a wider list of cameras.

Partly repeating what others have said, but this is my experience: * Even in macro mode, there is a limit to how close you can get. Try backing off until you get a clear shot. Even after cropping, this may be good enough for the web, since you're probably downsampling anyway. * Use a tripod or other camera support. The standard tripod mount is a 1/4-20 thread, so you can improvise a support from anything with a 1/4" hole in it (but if you're using a long bolt, use a nut on it so the end doesn't break through the camera case). The "ultra-clamp" is also handy for this kind of thing (available at most camera stores for about $20). * Use the 10-second self-timer so the camera has time to settle down after you press the shutter button (if you also have a 2-second self-timer, that might not be long enough). This can make a *big* difference when using slow shutter speeds. * Use the smallest available aperture (usually F/8) and as much light as you can get (if you don't have a manual mode, check the manual for a mode that optimizes for small aperture and slow shutter speed). * Close-up diopters can help-- if you don't have lens threads you can just hold it in front of the lens (or use duct tape). They're fairly cheap. * Standard photoshop skills apply-- contrast, sharpening, etc. For what it's worth, here are some macro shots I took with a cheap digicam: http://www.geocities.com/jszybowski/...rd/Adapter.htm The box is approximately 2"x3", the sockets are about 3/8" in diameter.

Those do most of their zooming by reducing the pixel area, giving up resolution to make the subject appear larger. That's the digital zoom. I have one of the cheapest (Toshiba PDR-M25) that has a 3X optical zoom. And, that still isn't enough to do real close-up work on small objects. The focus hits the wall at about 6", I think. Jon |

Thanks to all. Using the suggestions here I was able to get a decent shot
which I'd failed to get in about 4 dozen previous tries. This shot shows the chuck at the top end of the file rod, where you actually clamp the parallel machine file. I was unable to clamp a file so it was parallel to the file rod. On closer examination, I realized that the fixed jaw of the chuck was well and truly boogered and, amazingly, appeared to have been manufactured that way. See the image: http://tinyisland.com/images/FixedJawAsReceived.jpg My solution is going to be to mill the fixed jaw until it is clean and right and make a hardened shim to replace the removed material. Not being skilled at brazing, I'll probably epoxy the shim in place. I'll post details of the camera later. The die filer I'm using as a reference is a Keller Model 256. I'm having lots of fun working on it. Grant Erwin Ron Bean wrote: Grant Erwin writes: I get pictures that are semi-usable but nothing at all that can really be said to be in focus.

Grant,
My Olympus C-700 Ultrazoom digital has a "macro mode", but it only works when the zoom is set to wide angle. Not intuitive, since your instinct is to "zoom in" close. Try widening out the zoom and then moving the camera in very close to frame the shot you want. This works very well on my camera. -- Bob (Chief Pilot, White Knuckle Airways) I don't have to like Bush and Cheney (Or Kerry, for that matter) to love America "Grant Erwin" wrote in message ...

It's nearly impossible to hand-hold a camera for clear macro work. Light the work brightly/externally and turn off the flash. Shoot from different distances at highest rez and crop to detail. You could build a flash ring with LEDs if you're doing this very often, Grant. Tissue paper over the flash will work (as a diffuser) in a pinch if you have to have flash for shadowing. BTW, what I'm shooting are details of my die filer for the die filer Web page I'm building. I know there is probably a more specifically correct NG but I'm real used to this one and we have many knowledgeable regulars. rec.photo.digital might be your next step if we don't solve your problems. I don't follow it but have lurked and asked questions there (whenever I've had a problem) for years. -- Impeach 'em ALL! ---------------------------------------------------- http://diversify.com Website Application Programming |

That's a very good image from a relatively low cost camera. I've been using
an HP 215 that produces marginally acceptable closeup pics. There are some clip-on lenses from Tiffin for the 215 and other different brands of digital cams without threaded lens rings. If I can't get a decent flash image with the x1 setting, I'll try the x2 digital zoom from a longer distance. Machined metal parts are a challenge (at least for me) because of multiple surfaces, threads and other details. Sometimes suspending/mounting the part "on a stick" nearer to the camera than the background, with no other objects nearby gives very good results. For most of my limited experience with images for web pages, additional fill lighting is required for a decent image (I started with a video camera and a frame capture gizmo, went to a flatbed scanner and am now using the HP) and common incancescents are too cold/red for most types of cameras. Some flourescents aren't much better (haven't found a good compact screw-in flourescent), but this HP does seem to be compatible with a GE Cool White circle flourescent in a magnifier lamp at my table. I've picked up a lot of good tips from this thread that should improve my results, and thanks to those that offered them WB ................. "Grant Erwin" wrote in message ... Thanks to all. Using the suggestions here I was able to get a decent shot which I'd failed to get in about 4 dozen previous tries. This shot shows the chuck at the top end of the file rod, where you actually clamp the parallel machine file. I was unable to clamp a file so it was parallel to the file rod. On closer examination, I realized that the fixed jaw of the chuck was well and truly boogered and, amazingly, appeared to have been manufactured that way. See the image: http://tinyisland.com/images/FixedJawAsReceived.jpg My solution is going to be to mill the fixed jaw until it is clean and right and make a hardened shim to replace the removed material. Not being skilled at brazing, I'll probably epoxy the shim in place. I'll post details of the camera later. The die filer I'm using as a reference is a Keller Model 256. I'm having lots of fun working on it. Grant Erwin |

All the under $1K cameras I've seen have no shutter, no iris, and most have a pretty primitive optical zoom system, too. I think the Canon A70 is the cheapest digicam with full manual controls, including aperture and shutter speed ($200-$300 depending on where you buy it). It can take good pictures if you respect its limitations (slow lens). Their S-series cameras are similar, and cost slightly more. The G-series has a better lens, but it costs $700. They use a combined shutter/iris mechanism. Certain shutter/aperture combinations are unavailable because it can't open and close fast enough. This seems to be common for cheaper cameras. |

By far the best lighting available is sunlight, preferably morning. I can mock up a background with the back of a poster or sometimes butcher paper. You can shape the paper or add a poster to provide some fill. I can quickly get images suitable for color newsprint ads. When I'm in my poorly-lit shop, I use all the lights available - Overhead tracklights, flourescent worklights, and halogen portables, variously focused on the work or to provide bounce. The combination gives me pretty accurate color and good detail. Texas Parts Guy |

I just hold a jeweller's loupe in front of the lens, and with the
existing zoom feature and moving the camera itself in and out a bit, I can get decent closeups. Any machinist should have a loupe in his toolbox, if only for finding and picking those pesky metal slivers out of your skin. Dan |

calmly ranted: I did a lot of reading up of online tests and reviews before choosing what to buy. The Finepix series seemed to come out top for the price in most reviews of the time 2 years ago and I've certainly not regretted the choice. I did the same reading about 3.5 years ago and chose the Nikon Coolpix 995 for the very same reasons. g -- Impeach 'em ALL! ---------------------------------------------------- http://diversify.com Website Application Programming |

Very interesting thread! No one has mentioned the digital camera I bought a Costco about a year ago. It is a Minolta Dimage Z1 with a 10X optical zoom and 3.4 meg pixels. One of the autofocus options allows closeups to about 1.6 inches. I have taken lots of nature photos, as well as similar closeups for documenting electronic assembly work at the plant. Also the closeup capability allows great Ebay photos! My $0.02 worth. Paul |

Hi,
One can get a camera with most of the controls for well less than $1k. I have a $380 Olympus. This has: A 10X optical zoom (and a 4X digital zoom), In macro it focuses down to 1.5 inches (lighting can be a problem this close.) Exposure time can be manually controlled ( this may be electronic) The aperture can be manually controlled, ( but the range is a bit limited) It is just a bit too big for pockets. Jon Elson wrote: ff wrote: You probably need higher resolution (more megapixals) to get the detail you want. To get the most from what you have, use lots of light and a tripod to keep the camera steadier. The more light available, the smaller the aperature and hence more depth of field. Aperture? I'm pretty sure NO digital camera in the $200 range has an aperture, ie. an iris. I think you have to get into the $2 - 3K range before thay have that feature. All the under $1K cameras I've seen have no shutter, no iris, and most have a pretty primitive optical zoom system, too. Those do most of their zooming by reducing the pixel area, giving up resolution to make the subject appear larger. That's the digital zoom. I have one of the cheapest (Toshiba PDR-M25) that has a 3X optical zoom. And, that still isn't enough to do real close-up work on small objects. The focus hits the wall at about 6", I think. Jon |

If me, what should I do differently? If it's the camera, what other camera works better? Could be quite simple - put a magnifying glass in front of the lens, or even reading glasses. I may of misunderstood the question but you can get closer that way Grant Erwin Kirkland, Washington -- Maurice remove DOT for email ------------ |

Put the item on your scanner and scan it. You don't need a camera to get a
digital picture. Jim "Grant Erwin" wrote in message ... I'm no shutterbug. I'm using a digital camera that cost about $200.
