Digi-SLRs
by Bob Dove 05 Jul '05

05 Jul '05

Hi Adam and others, Firstly, I have no experience with dye-sub other than test prints Kodak mail me from time to time. All the Kodak prints are colourful subjects but none with Caucasian skin tones which is of course for a portrait photographer the test. Canon Digi-SLR 6 mP; this should be giving results akin to a similar spec film SLR with the obvious rider than unless you are using a Canon with the full format CMOS sensor your EOS lenses are not going to give their best. Most digi-slrs are using small sensors equiv to APS film format - as are most current compact digi-cams. Your digi-slr is giving you the interchangeable lens option and of course more control as to exposure via f/stop/shutter speed/ISO value et al. Your camera is highly regarded and is used by many pro's as a back up to the big brother SLR. Zoom lenses are a big expensive compromise! They are unlikely to match the definition/resolution of a good prime lens and many of the current compacts have 'simple' lenses of the 'Cooke triplet' type that are unbeaten for quality at the average 100th sec at f/11. There is then the autofocus of a lens that has an enormous depth of field - you shouldn't be able to go wrong with a good compact! However, a big zoom lens designed for full frame despite the myth that using said lens on 'half frame' gives better results 'cos you are using only the 'sweet' centre area of the image circle will not give the quality of say a Sigma designed for the smaller sensor size. But, a factor almost never taken into consideration is that interchangeable lenses wear their mounts. A fraction of a millimeter wear on flange to flange fit is magnified at flange to film or sensor and can prevent full resolution being achieved. A 'rattling good fit' is not good enough - especially with the smaller sensor formats! There are errors possible at flange to view screen distances too. Then there is always the Friday afternoon tea break model! Take your camera and lens to a good service shop and have them collimated. A good job can make your camera/lens better than new! Just like a service and M.O.T. Cheers, BD.

JPEGS et al

Hi Guys, I used a 'live cd' version of Suse 9.3, which loaded my Epsom R300 semi OK and printed a nice test sheet. This edition of Suse includes Open Office 2.0 (which I use in win as well) that prints as well in Linux as in win. I couldn't access images from my Windoze system however, Suse shows me the drives but I can't access them or write to them. Is this 'cos the are formatted NTFS? Do I need a Linux formatted drive to write to/load from? Mandrake Move however needed a special printer driver driver which Epson don't have yet. Re quality InkJet Vs. minilab. Minilabs largely use hybrid printers - real continuous tone photographic colour paper ('C-Type') and wet chemistry although Noritsu are now installing a minilabs with an Epson InkJet front end. The photo-colour paper is exposed to a 'virtual neg' via laser or LCD block via relay lens as most labs now dev the film and scan it to digital files which are 'flattened' tonally to an easy to print result. Most no longer print from a neg. This flattening of course removes a lot of the possible subtlety and tonal range that a neg/pos process provides. However, a digital file from your own camera - especially 'raw' or 'native' format that hasn't been JPEG'd already will produce better than InkJet from a hybrid printer. It is a sad fact however that the digital photographic market place is filled with hype rather than reality and many digital photographers just don't know what their equipment is capable of. Picture libraries are now asking for digital files ca. 40 mB in size to ensure that they have images capable of making an A4 mag cover or A3 dps. Of course, a 35mm trannie scanned to 48 bit will provide this! (Image size ca 7 x 10in @ 16 bits per channel is 40.9 mB - 2235 x 3196 pixels. The original trannie does of course contain more info than can be accessed digitally! It boils down to that if you are a pro' or keen amateur photographer you'll be taking your fully Photoshopped or Gimped files to the lab on a CD for real photos while if your 'normal' requirements are family happy snaps an Epson ('cos the clone inks are SO much cheaper) will suffice. But, even Epson and HP genuine inks fade fast (within six months for photo's on display in normal (i.e., mine) lighting whereas the photo-paper doesn't. I and photographer colleagues have been conducting longevity tests on IJ prints since whoever claimed that they were of photographic quality - they ain't! Horses for courses tho'! Cheers, BD.

Have you installed GimpPrint? I have a completely non-standard (as far as Linux is concerned) Canon S400 and I use CUPS and GimpPrint and its always worked straight out of the box (bet you really wanted to know that :o) ). Do you have OpenOffice installed (or anything with a decent Word Processor)? A technique I've often used is to open a blank document and then imported an image into it, then just printed the page with the image. It's a useful technique that I've used successfully under Windows, Unix and Linux at various times (assuming that you can print ok from the WP software).

"Relay" of FTP?
by Ted.Harding＠nessie.mcc.ac.uk 03 Jul '05

03 Jul '05

Hi Folks, Here I go trying to break the rules again .. or am I? When I dial-up, my "gateway" machine gets an IP address which I can find out. So, from outside, I can telnet, ftp etc. to my gateway. If I want to telnet to one of the machines inside my LAN, I could first telnet to the gateway, and then from there to any of the others. A bit cumbersome, but not a problem. However, if I want to FTP to one of my internal machines, it's much more cumbersome: first FTP to the gateway, then telnet to the gateway and from there FTP to the desired machine. I'm wondering if there's some sort of protocol for getting directly to an "internal" machine (whose IP address is not known to the Net) by a kind of "relay" via the gateway (whose external IP address is known to the net). There's an analogy in Internet mail, whereby you can force mail to aa.bb.cc.dd to be routed via AA.BB.CC.DD, by addressing to @AA.BB.CC.DD:user@aa.bb.cc.dd (so-called "routing addresses). So can I, for instance, do something like telnet @213.130.142.61:192.168.0.7 (where 192.168.0.7 is the address of a machine on my private LAN, and 213.130.142.61 is an IP address my gateway waas recently given on dialup)? And, similarly, something like ftp @213.130.142.61:192.168.0.7 ?? Or is there a different way to do it? Or no way at all? When I try the above on my LAN, e.g. telnet @192.168.0.7:192.168.0.1 I get "Aborted", and telnet 192.168.0.7:192.168.0.1 gives me 192.168.0.7:192.168.0.1: Unknown host and similarly "Name or service not known" with FTP, so presumably I've got the details wrong above, if it's possible at all. But you get the idea ... With thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 03-Jul-05 Time: 21:34:12 ------------------------------ XFMail ------------------------------

MS settles with IMB
by Ted.Harding＠nessie.mcc.ac.uk 02 Jul '05

02 Jul '05

Hi Folks, I read today: http://business.timesonline.co.uk/article/0,,8209-1677235,00.html that MS have agreed to pay IBM $775 to settle claims going back to the 1990s. In particular they are related to a case against MS by the US Givet that its practices caused the demise of IBM's OS2 operating system. I recall that, in 1990-91 (i.e. before Linux came on the scene), I got seriously interested in OS2 as an OS for the IBM PC that offered functionality similar to the capabilities of Unix (which, already having experience of, I was eagerly looking for on the PC, being frustrated with the limitations of DOS and disgusted with the marshmallow experience of early Windows -- pink, sugary, squodgy, of no nutritional value, nauseating in large quantities, and liable to adhere tackily to whatever you were trying to do). Then, of course, came Linux; and, personally, I've never looked back. But I think the worlds of both serious and consumer computing were deprived, when OS2 sank, of what would probably have become a great OS. Ironically, at that same time (1991) I also learned of the existence of the MS project for Windows NT -- yes, it goes back that far! This, too, seemed as if it might offer Unix-like capabilities, and was another thing I was keeping an eye on in the hope that the PC would be enabled to yield the performance that its hardware was capable of. For some reason, however, it was many years before NT became generally used, and then mainly in "the background" in the corporate and institutional sector. It's satisfying, after all these years, to learn that IBM is (in effect) vindicated; but depressing all the same to be aware that a promising initiative had died so early on. Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 02-Jul-05 Time: 09:19:26 ------------------------------ XFMail ------------------------------

Is this for real ?
by Wayne Stallwood 01 Jul '05

01 Jul '05

http://www.merkeylaw.com/article.php?story=20050621145053855&mode=print Check out items 40 downwards for maximum amusement This one is a classic. "60. Perens posted Internet messages on LWN.net stating to Linux and OSS members that “Merkey works for SCO,” and that “Merkey should be placed in a file of people to be killed”. Merkey has not or ever worked for SCO or the Canopy Group." Is the US legal system so broken now that you have to be careful using terms such as killfile. Other classics include "46. The beheading and murder of United States Citizens in Iraq, Saudi Arabia, and other countries have been videotaped, converted to MPEG and other images for viewing on the public Internet through the use of OSS and Linux software and computer technology developed and purloined by Linux and OSS members and illegally exported from the United States. 47. Companies which sponsor, endorse, and support OSS and Linux, and those acting in concert as their advocates have been unwitting participants in wholesale technology theft of United States developed technology and sponsors of domestic and international terrorism.
