The radio in the mid of the picture is a Stromberg-Carlson 325J - just
finished and sings like a bird. The radio on the right is the FADA 43z that I am waiting for an interstage transformer for but should be up and running soon. Brian -- Posted via a free Usenet account from http://www.teranews.com |

Is there any chance you could retake that photo with about 1 stop more
exposure? |

Try this one - don't know why it is sooo dark the email pics I sent to

(My Olympus E-500 can take 1.5MB JPEGs that produce sharp, artifact-free 12x18 enlargements.) If you like, I'll post one. I agree that 50K to 100K JPEG should be enough for a Web posting. The image should be reasonably sharp, and if it shows any artifacts, they should be limited to a bit of scan-line aliasing ("jaggies"). I would urge Brian to check his camera's settings. My guess is that it's set for too much compression and unnecessarily high resolution. It's my current opinion -- which might change -- that high compression degrades the image more than low resolution. I therefore have my Olympus set for 2.7:1 compression (the lowest possible for a JPEG) and 1200x1600 resolution. |

I also sent a copy to my works computer and again not dark. I see the first pic here on the newsgroup is dark. I did not retake the picture but brightened in Kodak easy share program. Didn't even notice the size until after I sent it. Agreed that pictures should be under 100K. Attached is a picture of some more of my radios. I used the lowest setting on the camera, used explorer to resize to email myself it and attach it here. Comments? Brian -- Posted via a free Usenet account from http://www.teranews.com |

Shooting everything at maximum resolution would quickly fill up one's card. It's better to find the minimum resolution and compression that produce an excellent image in your usual print size and use that consistently. You can then switch to higher resolution for shots you intend to enlarge more. Image quality varies among cameras. It seems that DSLRs have better sensors and processing. The image posted here would have been of very poor quality had it been at 1/10 the posted resolution (250K versus 2.5M). Note the severe compression artifacts on at least one of the radio's grilles. |

That was probably the case a few years ago- but today - with the price of cards so low - there isn't near the "cost" for shooting hi-res /low compression there used to be. Of course it makes sense to understand the tradeoffs - and choose the right resolution / compression for both the subject and the target media. But since I don't always know that in advance - I tend to keep my camera at 2048 X 1536 and compression at minimum (though I can set it to none, I can't tell the difference). At that setting - I can get 624 pictures on a 1Gb card. Of course at 640 X 480 with max compression I can get 10406 pictures on that same card - but what on earth would you ever take that many pictures of? With 4Gb and larger becoming more and more common - it gets hard to justify low res and /or high compression. Image quality varies among cameras.

Which camera do you have? The lowest JPEG compression is 2.7:1. This degree of compression seems to have few, if any, visible artifacts. |

There's also the option (actually the necessity) of dumping the card to disk. I try not to let too many linger there, in case something happens to the card, or god forbid, the camera. Even at that, with a one gig card and a 7.something megapix camera, that's a hundred or so shots...even with the odd mpeg mixed in. Sure beats the old days when the choice was between a 12 or 24 exposure roll. The cost/frame equation falls completely apart when you realize that unlike film, you can reuse the card. Why anyone would store anything on one for any longer than it took to get to a computer is beyond me.

Why anyone would store anything on one for any longer than it took to get to a computer is beyond me. I periodically dump my cards to an external hard drive. However, I don't wipe the card until it's full. Why? Well, it doesn't hurt to have two copies of something. Also, flash cards have a finite number of write/erase cycles. I think it's tens of thousands of cycles, but it seems to me that the less often you write to the card, the longer it's likely to last. There is also the matter of having prints made at Costco. (I don't use an inkjet printer. Costco is better and cheaper.) It's easier to pull the card from the camera than to copy the image from the hard drive back to the card (assuming it's a "recent" photo). |

Point well taken - in fact can be extended by noting it's usually easier to change cards in modern cameras than film traditional cameras in most cases. Sure beats the old days when the choice was between a 12 or 24 exposure roll. Indeed - plus bracketing - which used to be only for those shots where there truly were (usually) very poor or unusual conditions - now it's no big thing to bracket a half dozen and an equal number of composures of the same subject. On glimpsesofmeridian - I've posted a handful of the train pictures - out of a choice of nearly a hundred. Some of the hand-held night shots are totally trash. but as can be seen - a couple came out pretty decent. best regards... -- randy guttery http://www.glimpsesofmeridian.com Trains, planes, steam and stuff... |

Composures? Given the appropriate software, bracketed shots can be combined to produce a picture that shows detail in both the highlights and shadows, over a ludicrously wide brightness range. |

Even my admittedly poor camera has a mode where it will shoot bracketed exposures, three of them for each shutter press, at a selected bracket of +/- .5, 1.0 or 1.5....automatically. I've seen some instruction on how to combine the shots in layers to bring out detail in shadowed areas, without washing out the same in brighter areas. The effect is almost surreal...like a video game scene. My thought, although I haven't yet tried it yet, is that much could be done by saving the same exposure several times with various settings of gamma and/or brightness, then layering back the copies to the original. The only software I have to do that is Corel Photopaint, although I just downloaded a copy of GIMP...freeware, but highly recommended. jak jak |

That's the "usual" as trying to get many more without you (or the scene) moving gets problematical. I've seen some instruction on how to combine the shots in layers to bring out detail in shadowed areas, without washing out the same in brighter areas. Photoshop has provisions to not only work in areas - but to handle shadow, midtone and highlight areas separately; lightening / darkening / increasing and decreasing saturation - and you can select to apply either to the entire image or specific areas. Add that to the ability to handle layers each with such capability - and you can do some pretty neat stuff. Fortunately - Minolta (and the successor Sony) has a multizone exposure system that usually does a pretty good job of "getting the details". Of course like all such "stuff" you can tell it to mind it's own business and either use simple or totally manual controls as you wish. Sometimes in very low light - it's better to shut the autofocus off and do it by hand - so you get the exact subject in focus - rather than the camera guessing at what is supposed to be in focus. In good light - it's not a problem - as the lens is (usually) stopped down enough to get everything "good enough" - but when the lens is wide open - it's time to give the automatics "the boot". The effect is almost surreal...like a video game scene. Yeah - that's something I have to watch - sometimes when "tweaking" - I can get a bit overboard - and need to quit "pushing" things before they become "unreal"... My thought, although I haven't yet tried it yet, is that much could be done by saving the same exposure several times with various settings of gamma and/or brightness, then layering back the copies to the original. You could - but sometimes it's better to do a transformation of the original by the values (usually of some specific area) of the brackets (or tweaked copies). Photoshop let's you have best of both worlds - as you can apply a layers as a transitional mask (add, subtract - or even multiply or divide depending on effect desired). Then if you screw it up - you delete the layer - and the original is untouched. The only software I have to do that is Corel Photopaint, although I just downloaded a copy of GIMP...freeware, but highly recommended. Fortunately - since much of my work requires Photoshop and several of it's siblings - I "get" to use Created Suite which has all the "toys". I use mostly Photoshop and GoLive (web work) though I find myself using Illustrator more and more lately as I work in more technical "stuff". I also have the "non-suite" package Adobe Audition - which used to be "Cool Edit" for working with audio like Photoshop does graphics. best regards... -- randy guttery A Tender Tale - a page dedicated to those Ships and Crews so vital to the United States Silent Service: http://tendertale.com |

If you're bracketing +/- two stops (which would be normal for capturing a wide brightness range) and the camera is set for Program, the aperture might change. |
