Too grainy for 35mm, but I shot a roll of it in a Zeiss Ikonta 520 (used eitehr 620 or 120 film rolls, and got sixteen shots per roll -- sorf of pushing the size thing for that film. :-) Enjoy, DoN. Ayup. It was too grainy for just about anything I was doing. And even Tri-x pushed once was not as grainy as I recall. Gunner |

But green really is still green! Ayup. But it can be processed in digital...sometimes more..sometimes less. With color negative...it could be "tweaked" a bit. With slides..you were well and truely ****ed. Got lots of green slides ..sigh. You could slip the slides into the enlarger and print to a direct positive print paper (I remember that Ansco had one which was on white plastic instead of paper) and tweak the colors with filtration, just as you do with color negatives. You can also get some weird looking prints using polycontrast filtes on the color paper. :-) Ayup. But the cost! Printing color really WAS expensive, in film, paper and chemicals. And Im more of a B&W affectionado. I love good black and white. Ive done a lot of black and white with the digital camera too. And sepia toning. I ought to dig out a couple and see if I can process them to something less green with the scanner... You should be able to. Ideally -- save as something other than jpeg, correct and do everything else you want, and then save to jpeg if you want it in that format. Each time you go into or out of jpeg, you lose a little more detail. For most of the stuff that I do...its for the computer. 640x480 frankly..is good enough. My current Oly C-4000 with a 8gig card in it allows me to shoot up in the 2000xsomething or other (mumble mumble) and have photos that are less than 1meg...which frankly..is good enough. If I was going to do more 24x36" prints again..Ill drag out the 4x5s. I have a few boxes of Plus-x 4x5 in the freezer still...and the local camera shop gives me a break when developing..cause I supply the tank, racks and everything but the soup. Or even the 330Fs Enjoy, DoN. |

I tried to steer those folks into B&W. 40 years ago when I did TV repair, most people had a definite green tint to their TV sets. They would complain about a bad picture when you replaced the CRT and did a complete setup to factory standards. Ayup. The eye tends to translate green easier than most other colors..and a **** load of people tend to be green oblivious. Used to drive me nuts in the lab. One of the reasons Im still..still a fan of B&W Gunner |

No, I haven't added any filters, although I'm interested and I'll take a look at those. I've only used GIMP for a couple of years, and almost strictly for professional work that involves very mechanical kinds of hand-retouching. It's all straight photography. I haven't ever used overal image manipulation, except for the basic corrections -- contrast, color, density, etc. Mostly I clean up backgrounds, correct mistakes, silhouette, and related things. But I know there are a lot more Photoshop things you can do with GIMP if you go for the open-source add-ons. I'll have to look into it further. Thanks again. -- Ed Huntress |

I thought that some of them will take multiple exposures? Again, I don't own a good one, so I don't know. Some will. I think that my D300s will do it, but I have not needed that feature so far, so I tend to forget. Time to re-read the manual, I guess. Always good to do after using the camera for a while to pick up on things you missed earlier. With film, I try to do it with one of my two cameras (Calumet 4 x 5, and a Yashicamat 6 x 6) that allow it without moving the film. My F2 won't allow it; they started that with the F3. Or -- put a lens with between=the-lens shutter on the camera on a bellows, and you can do it with the F2. :-) Yes, but jeez.... :-) You'll get a kick out of this. I have a behind-the-lens air-bulb shutter I used with process lenses on my view camera, which I used for making Tri-Mask in-camera separations for the Trenton Times. I have put that sucker in *front* of a lens on my Nikon F2 for shooting multiple exposures. It's a big interleaved shutter. That will do it. Or an electric shutter such as I used when building a camera from a large lightbox to 2x2" glass film -- for integrated circuit layouts. Though usually I was running the lightbox on a Gralab timer instead. :-) The lightbox was two neon transformers and white neon folded in square-wave shape behind a diffuser. But I don't get into those gymnastics anymore. Understood. However, I did a series of nightime architectural shots, for a portfolio, with my F2 and a 28mm shift lens. Ah -- the PC-Nikkor. Yeah, one of them. It belonged to my partner at Windsor Advertising. He had a gazillion lenses -- and an 8 x 10 Calumet that we used to shoot giant trade-show Translites for Canon calculators and Prince tennis rackets. They were around 20 feet wide. Those were fun times. Indeed so. My largest format at home is 4x5 -- both a view camera and a Crown Graphic (like the Speed Graphic, but without the focal plane shutter.) Yes, the 8x10 Calumet was what I used with the same light box for printed circuit layouts. Two color layout tapes, and filters for the two shots for the two sides -- we didn't try multi-layer boards. :-) [ ... ] 'Second that. I even use one for doing test shots, to balance the lights, when I'm doing the final on 4 x 5 film and using a Minolta Flashmeter IV for exposure. So you have not depended on the results from the digital, except as a rough guide -- so you may not have seen the effects of the long open shutter time, since you probably did not bother blowing up the image on your computer monitor. [ ... ] Actually, for that Amada brochure, I wound up using the digital shot from a Nikon D5000. O.K. A bit out of my price range. :-) That and the single-digit D series. :-) [ ... ] Was this a single shot, or a multi-flash one like the above? For single shot, I would expect the D5000 to be very good. A single shot with my (then) new Smith Victor daylight fluourescent scoops. I was using too many new things at once not to have backups. I have the digital shot on my hard drive if you want to see it -- before and after I worked it over with Gimp. You could not get it to my mailbox. There is a size limit of 60K (to keep virus e-mails out of a couple of small mailing lists I host.) Of course, with the Nikon gear, and a shooting budget, I would go with the Nikon and a cluster of SB-800 flash units. The camera can be set up to run all of those as a slave, and when you take the shot, it first fires a lower intensity pre-flash from each (triggered by the flash on the camera and metering it in the sensor), and then sends to each how long a flash duration is required from that one, so when the shutter finally opens for real, you get a properly balanced illumination. I've got *one* SB-800, but not a whole herd of them. :-) Again, I spent too many years lugging 100 pounds or more of flash heads and power packs, and even my big Bowens Monolights into the field. No way, Hose-A. The SB-800 flash units are very light -- often used camera top on 35mm SLRs. A camera bag with a half dozen of them would be lighter than my bag full of lenses. You can clamp them pretty much anywhere, or just set them on a tabletop. And no wires to string -- the camera and the flash units communicate by encoded flashes. :-) From now on, I'm going with the daylight fluorescents. Lots of field photographers are using them now. I'm convinced, after seeing the densitometer readings on digital images from my gray card and Macbeth Color Checker. I shot the latter in daylight and then in daylight fluorescent with the same camera. You can hardly tell the difference. Pretty good, then. But probably about the same weight per head (for just the lamp and the socket) as the SB-800. I'll buy a good digital some time, but I haven't had enough need to justify it. I don't shoot for fun like I used to, and I haven't shot a magazine cover for around a decade now. I rent when I need to. While I'm back into shooting for fun. For quite a while, I worked where classified stuff was common, and a camera was a no-no, so I did not take many shots during that period. Now I'm retired, and having fun with the digital SLRs from Nikon. It's a great hobby. Maybe if I retire I'll take it up again. I *am* retired, so I did. :-) Enjoy, DoN. -- Remove oil spill source from e-mail Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

I keep looking ;-) I'm always interested in finding the magic pixel-munger that will make my job easier. g I've not found it yet, and I used Photoshop from the first few months it was on the market; and PhotoStyler before that. Meantime, a program that allows easy selection, paths, and the other fundamentals -- with speed and accuracy -- is all I need. I have a fast desktop with 6 GB of RAM, so Gimp works fast enough to satisfy me. One thing I could use, though, is conversion back and forth to a really broad colorspace that has a lightness (black and white) channel. I used L,a,b with Photoshop. You get superior results with unsharp masking by working only on the lightness channel (it avoids color artifacts), and there are other things I like to do with it. There may be a plug-in for doing it with Gimp, but I haven't looked. I've gotten away with lesser colorspaces because I've done work mostly for the Web lately, and it's not very demanding. If you know of one, I could use it. -- Ed Huntress |

Thanks, Leon. I can use that. Playing with colors in L,a,b or other colorspace that has a density channel and two-pole color channels (like HSB) is very tricky. I see from the article that the author has tried to rationalize it. I'll have to look it over. Thanks again! -- Ed Huntress |

You can use reflectors and diffusers to do essentially the same thing with, probably, more bother. Try some diffusers made from thin white plastic in front of your flash and (probably) three or four flash heads and see if you can't get the effects that you want. An electronic camera is nice as you don't need to waste all the trial shots that you do with film. Thats what I figured. Its been years since I did it with film...a stroke got in the way..and I dont remember much about what/ how I did it. I know this question doesnt show it..but I used to be a fairly competent semi-pro photographer. Shrug. The ability to break it down and set it up quickly would be nice as well. Im running out of floor/shop space. Anyone have any good links to "inexpensive" slave strobes? Or anyone have any older slave strobes that they have outgrown? Gunner Quit thinking strobes! It's 2013, Floods will do! If it looks good to your eye, it will look good to the camera. And if you really want to make it pop, get a camera that does HDR Mode - Multiple shots, automatically bracketed exposures, and the computer matches and blends the bright areas with the dark areas. Automatic Dodge & Burn. The equivalent ISO of a Digital camera is miles ahead of film - the days where you had to use ISO-25 Kodachrome to get fine grain and good detail are long over - Besides, so is Kodachrome. Get a batch of 300W or 500W Quartz stand lights, I'm sure you can come up with *that*... And for reflective surfaces you rig up some cloud diffusers in front, or bounce them off aluminized screen fabric. Think Windshield Spring Shades, the aluminized side. Try to get the lamps all close to the same color temperature - the camera can correct the color temperature, but not if one side is lit at 5000K and the other side at 2700K - it'll freak. For a background, new clean off-white canvas Painters Tarps. Already sewn together, cheap, big enough to drape on the wall and then bring out on the floor or table. And easy to dump in a commercial washer with a box or two of Rit Dye if you want colors. And when you're done taking pictures, use the tarps for painting. The paint splotches will add extra pizzazz to the photos, and nobody will steal your funny colored dropcloths - they'd stand out in even a satellite photo.

[ ... ] Quit thinking strobes! It's 2013, Floods will do! If it looks good to your eye, it will look good to the camera. Agreed -- at least if you let the camera learn the proper color balance for the lights you have. There are a lot of presets for various light sources, and at least some have the ability to measure the color balance off a neutral gray card for a given setup -- and use that. [ ... ] The equivalent ISO of a Digital camera is miles ahead of film - the days where you had to use ISO-25 Kodachrome to get fine grain and good detail are long over - Besides, so is Kodachrome. Yep. I'm shooting up to ISO 3200. (And back in the days of the Kodachrome you mentioned, it was ASA-25, not ISO-25. :-) IIRC, the other common system in use then was DIN -- a very different scale, and if you were lucky, your exposure meter was marked with both scales. :-) Get a batch of 300W or 500W Quartz stand lights, I'm sure you can come up with *that*...

Unless you want to use the color difference for modeling shapes. Let the camera learn the proper white balance for one set of lights alone, and use the other to make interesting color shading. For a background, new clean off-white canvas Painters Tarps. Already sewn together, cheap, big enough to drape on the wall and then bring out on the floor or table.

I an going to wait till I have the new air conditioning in place, and a new workbench finished so I have plenty of light and I'm less likely to lose any of those tiny screws. The fan bearings went in my A/C the other day. I picked up a new GE 8,000 BTU at Sam's Club for $187 yesterday, but I'll have to wait a few days to get help to lift it up, and put it into the wall. The old unit was ~ 10 years old, and a new fan was $192 wit a six week wait. I doubt the old motor is worth repairing. From the high pitched death wail it let out, I would expect to find badly worn shafts and chewed up sleeve bearings. |

Id like to build a lightbox..but it needs to be big enough/rugged enough.. to put in a dirty, oily part or piece. Something for shooting photos for Ebay for example. Ive seen how some Ebay companies like Reliable Tools do it..but I dont have that kind of floor space (theirs is 50'x50' with huge movable fill lights in towers on wheels. So Im going to need something useable with at least 3 strobes and operational via slave flash. Anyone have any links etc etc for simple designs suitable for what we do? Gunner Oh..I use Olympus Camedia C-4000s, C-3030s and C-3000 cameras. Cheap, take good photos and are rugged as hell. Gunner You don' need no steenkin' lightbox. About any aimable strobe compatible with your camera will suffice, just one will suffice nicely. The other accessory would be an aluminized umbrella, available for about $30. The backwards-aimed strobe bounces off the umbrella. Many excellent professional photos of technical objects, including photos for glossy corporate annual reports, have been done this way with a single bounce strobe. Been there, seen that done. The pro photographer was Al W at Honeywell, Inc. I've used an Olympus FL-40 which works with my old Camedia 2500 and will also work with C 3030, C 4040 and C 5050. |
