Heavy duty camera for photographing "ebay stuff"

I am looking for something heavy duty, as in: 1) Something that would not fall apart from taking up to 500 pictures per day 2) A camera that does not take a long time to recharge flash 3) A relatively sturdy camera 4) Camera that is good for photographing "things", like lathe chucks and electrical fuses, for example. 5) Camera that does a good job with minimum fuss in the hands of non-professional photographers. Personally I would just get a cheap camera aimed at people looking to take a few snaps of their holidays. Spend $50 tops. It should meet all of your requirements. Yes you could spend some money on proper lighting, special macro lenses and all that ******** but you should consider whether any of your buyers will really give a **** about whether there's shadows cast because you used an in-built flash. They won't. And do you want to spend serious money on something that will be used over and over by different people and more likely to get damaged? I am paying them by the hour. If they have to stand around and wait for the flash to recharge, pictures to get processed by slow CPU, etc, it will be expensive for me. The quality of pictures does matter, not in the sense of photo art, but in the sense of conveying what is being sold and creating a good impression. All the more reason to avoid using flash if possible. Avoid $50 cameras because you do not have any control over the exposure. Get a camera with independent control of aperture and exposure time as well as exposure compensation so reflection off a white wall does not swamp the dark object in front of it For small stuff macro mode is a must as well as tripping the shutter without touching the camera on a tripod (I do not have a cable so I use a 2-second timer). A light box for small items is highly desirable. You don't need to spend a ton. I made mine for about $5: http://www.flickr.com/photos/2768312...7625011848457/ I use a Cannon A720IS. My previous camera was also a Cannon. I like the option of both non-rechargeable and rechargeable batteries. Pictures get edited in Irfanview. Michael Koblic, Campbell River, BC |

Michael Koblic, Campbell River, BC I think you are asking a bit much of the people he described. They aren't professional photographers in any reach - except that he's paying them to take pictures. A properly working AUTO setting would be better. But I agree about the light box. also - What they want is a JPG file - not RAW file. RAW gives the user a lot of capability in post-processing, but that takes talent and proper software. The more one spends on the camera itself (within reason) the better the camera does in it's own post-processing to deliver a better JPG. AND - usually - the more options the camera offers in setting those parameters. I stand by my Fujis... Other people love their Cannons. (My Dad was a Pentax man - Go figure) |

The result will be some annoyingly flat photos, but that's better than shadows in which you can't see anything. If it were me setting it all up for a non-expert photographer to do the work, I'd use two big lights, each at 45 degrees from the lens axis, or maybe 60 degrees, and I'd hang really big drafting-paper sheets in front of each. The ideal is to have the sheets as far from the lights, and as close to the subject, as possible. I'd use light stands and gaffer's clips (spring clips, like big clothes pins) to hold the diffusion sheets. Sometimes I do the same thing with transmission umbrellas. Regular reflection umbrellas don't work out very well for that task because they are too far from the subject and you don't get enough diffusion. -- Ed Huntress |

I got one that can reflect, or the black backing can be removed and light passed through it. This is similar to mine: http://www.bhphotovideo.com/c/product/423628-REG/Impact_UBBW30_30_Convertible_Umbrella.html I've picked up several 60's era light bars dirt cheap at yard sales and set them up on cheap tripods, bouncing light off the ceiling. There's all manner of very inexpensive ways to light things and soften the light to avoid glare and flash hot spots. Jon |

When used in b&w, they'd light up the background so much that you sometimes couldn't see where the face ended and the background began.

I'd use light stands and gaffer's clips (spring clips, like big clothes pins) to hold the diffusion sheets. Sometimes I do the same thing with transmission umbrellas. Regular reflection umbrellas don't work out very well for that task because they are too far from the subject and you don't get enough diffusion. All true, but situation dependent. But with machine parts, I've found the diffuse flat light works pretty well. My shop is painted white, and I use a studio flash pointing at the wall behind the camera. The next step up is a ring flash on the camera, plus a white tent. The next step is crossed polarizers, where the camera lens has a linear polarizer, and the lamps have a perpendicular polarizer. This eliminates all specular reflections, and makes shiney metal vanish. One usually detunes the setup so the metal will show just enough. War story: Many years ago, on an Olympus Camera group, I noted that the pros photographing models all seemed to use Hasselblad cameras with big ring flashes, which flattened things, which didn't seem like a good idea a good idea with such models, and expressed mystification. The answer that came back was that the ringflash eliminated the bags under the eyes from to much partying, and too many controlled substances. Oh. Never mind. Joe Gwinn G I think they were pulling your leg. There was a style in fashion photography, begun in London in the '60s and used off and on for decades, in which the models were made up and lighted for dead-flat facial appearance -- almost like cardboard cutouts. It went along with Twiggy-style bodies and skinny legs jutting out at odd angles. When used in b&w, they'd light up the background so much that you sometimes couldn't see where the face ended and the background began. Then some dark eye and lip makeup made the eyes and lips look like they were suspended in space. Here's Emma Watson (today's Twiggy) with the flattened lighting but without the background effect, with a couple of eye sparkles and a pair of kickers on the hair to modernize the look: http://www.fanpop.com/spots/emma-wat...ma-watson-wall paper Interesting. Can't say that I care for the current fashions in fashion photography either. But I think they were serious about the partying. One did hear wild stories about wild parties. Joe Gwinn 'Could be. I never did fashion work -- at least, not with models. I photographed clothing without anything inside of it. g My agency partner had been Special Projects Art Director for Y&R, and he cued me into the lighting and other techniques used in high-end advertising work, but I had little chance to use them. -- Ed Huntress |
