peter_koning2 Posted October 17, 2001 Share Posted October 17, 2001 I've visited a photoschool, a professional lab and others. And I'm very disappointed.They are not very cooperative in letting me use their transmission densitometer; belief me that is an understatement.They probably think I want to steal something.By the way I also told them that a reasonable fee would be acceptable. Nevertheless I heard that you can measure the negs using a spot meter. If that's trough how does it work. Where can I find information about alternative measuring methods instead of using a densitometer. Link to comment Share on other sites More sharing options...
neil_poulsen1 Posted October 17, 2001 Share Posted October 17, 2001 Check ebay. I picked up an old MacBeth that works just fine. Not that all old MacBeths are going to work well. <p> Another possibility is to keep checking. You are bound to eventually run into an organization that has a customer focus.

jorge_gasteazoro Posted October 17, 2001 Share Posted October 17, 2001 yeah, I just got me an x rite for 150 bucks, but you have to make sure the seller will guarantee the item, previoulsy I bought an Eseco supposedly in "excellent" condition and working, when I got it it would not zero and it would not make the same reading from one time to the next, of course the seller tried to tell me I broke it, and that I did not know what I was doing because he "knew" it was working when he sold it to me.....anyways to make a long soty short, after numerous fraud complaints to various gov. agencies I got my money back...but it was a hassle. So let my experience help you, there are good deals on E bay, but just make sure you can get your money back in case you are not happy. Link to comment Share on other sites More sharing options...
david_rose3 Posted October 17, 2001 Share Posted October 17, 2001 If I rember correctly, Phil Davis describes a method for using a spot meter as a densitometer in his book "Beyond the Zone System". You might also consider getting a density step wedge, which would allow you to estimate density by either visual comparison or by contact printing side by side with your film. Zone VI Studios used to do film density measurements for a nominal fee. When Calumet originally took them over, I think they still offered the service- I don't know if they still do. I also recall an article in View Camera by Joe Englander called the "Tone System" that controls negative and print density using a step wedge rather than a densitometer.

jorge_gasteazoro Posted October 17, 2001 Share Posted October 17, 2001 Oh sorry, to answer your question, if you get the "New platimum print" by Sullivan & Weese, there is a chapter on visually assesing densities using a calibrated step wedge.

bong Posted October 17, 2001 Share Posted October 17, 2001 Here's an article by Jon Fishback that may help: <a href="http://www.heylloyd.com/technicl/fishback.htm">The Ultimate Monochrome Print</a>. You'll be spending some time in your darkroom, though. Link to comment Share on other sites More sharing options...

don_welch Posted October 25, 2001 Share Posted October 25, 2001 Peter, <p> I bought an X-Rite densitometer on eBay for about half price. It was used but well cared for, and it works very well. Yes, there are ways to use a spot meter instead, but it's not nearly as exacting as a real densitometer. You are still going to be approximating real density measurements, so you might as well get a step wedge and make visual estimates of comparison prints. <p> If you are doing extensive film development tests, as I have spent the last two months doing, a real densitometer is indispensable. I could never have finished my testing if I had waited for chances to use someone else's machine. It's not cheap, but it can certainly be worth it in time savings.

jorge_gasteazoro Posted October 26, 2001 Share Posted October 26, 2001 Peter, I put myself through college working at a photo lab, many times techs are reluctant to let people they don't know use the densitometer because it is an expensive piece of equipment and more importantly THEIR process depends heavily on corrrect measurements. If you by mistake change a calibration and/or a zero setting it can cause a big headache for them, you need to develop a relationship with them and show them you know what you are talking about before they will let you use their densitometer. On the other hand when people walked into my lab and asked to use the densitometer and I did not know them I offered to read the negatives for them at no charge. Most people were happy with that. <p> As to a densitometer from E bay this is a good idea, I got me an X rite form e bay for about 150 bucks, is all beat up but it takes consistent readings so I am happy. This is the key, make sure the seller will let you return the item if you are not happy. If that is the case then go for it, there are some good deals to be had at e bay.
