  1. Hi Carla, Greetings from the Emerald Isle! Well, I'm back at work just one week and already well into my supply of Prozac and Valium, washed down with an endless supply of office coffee! The .jpg v. .JPG problem has caught out quite a few users; an error message would be great, and I hope my recent post clarifies the matter. While I was away, Mike our chemist managed to drive his bicycle (although he insists a leprechaun pushed him) into a ditch. A damaged front wheel gave me an idea for a low cost, simple, but precision light array for RTI. Construction is within anyone's capabilities. More details soon. With best wishes, John. PS Expect a few $$$ donation soon.
  2. Ansley, go to http://www.den4b.com/?x=downloads&product=renamer ReNamer renames file tags. Download the (free) installer version from the page above. Just install and run. You specify the change you want (in this case change JPG to jpg). You can select individual files to change, or batch run a number of files in a folder. We use it to convert from Adobe's .JPG to .jpg. It's easy to use. If you have any problems, please PM me! John.
  3. Hi everyone. I'm just ending a few months' sabbatical. I don't really want to go back to work, but someone has to pay for my beer. I'm intrigued by Ansley's processing problem. I read the XML file she posted, and her images appear to be tagged .JPG, e.g jpeg-exports\CA-LAN-374_p1_spJ_e21-12.JPG. We had a similar problem some months ago, finding that the software recognized only lower case tags (.ie .jpg) and not upper case (i.e .JPG). I note she wrote " I re-processed (as a new project) an old photo set that had worked in the past, and it processed as a PTM again with no problem. " Is she perhaps using a new camera, or another RAW-to-jpeg conversion program? I'll be posting soon details of how the local fairies (common in Ireland) crashed my colleague's bicycle (with him on it) into a ditch, and how this minor catastrophe resulted in the construction of an inexpensive but accurate RTI light positioning system.... Beer beckons! Good night. John Anderson
  4. Hello Graeme. Thanks for taking the time to give so much information. Just like to point out that the very last link July 2013 http://www2.arts.kuleuven.be/info/bestanden-div/images/MB Is dead. Best wishes, John Anderson.
  5. Hi Carla, I too would be be interested. PM'd Ansley twice, but no reply....
  6. Hi Carla. Hope you folks all well down in SF. We tried the fix - shortcut to the .jar exec. It works. However, right-click on Windows icon and 'Open With' might be be more elegant solution. Best wishes. John.
  7. There is an existing post which might be of help here http://forums.culturalheritageimaging.org/index.php?/topic/61-difficulty-launching-rti-builder/
  8. Try uninstalling it completely, including manually removing program elements from the Prrogram folder in C drive. Also, type 'regedit' in the search box to access the registry. In the tool bar click 'Edit' and 'Find.' Enter 'RTI Builder' in the search box and press return. Wait for Windows to locate any entries. Right click on a found entry in the right-hand pane, and press delete. Press 'F3' to search next entry, untill all have have been deleted. Reload RTI Builder and see what happens. Be careful with registry edits! If the Windows icon reappears, right-click it and select 'Open With'. A drop down list of programs should appear. If RTI Builder is in the list select it and press 'OK'. The Windows icon is a default. It means Windows is not associating it with an executable program. Regards, John.
  9. Hello Anstey, by way of experiment, we recently installed RTI Builder on a Win 7 notebook. Yes, it works, but extremely slowly. Can you give more information about your PC? How much RAM is available? Before you reinstalled RTI did you remove registry entries? Mods should be on line soon. Regards, John.
  10. Oh Lordy! All Heaven rejoices. My AIC Guide has arrived! You will have read in my previous post of how the good folks at AIC snail central shipped my order by North Korean-registered tramp steamer, the S.S. Escargot, and how the ship, crewed by members of the Mukkinese tribe, was last seen serenely sailing up a long-forgotten and uncharted tributary of the Mississippi River. Well, it just so happens, that an elite squad of Navy Seals managed to get aboard, and threatened the motely crew with a good wash (the very mention of soap and water is anathema to the Mukkinese) to make them divulge the whereabouts of my package. This was quickly located and handed over to a special courier, who transferred it under armed guard to a secret US Air Force base, where it was loaded aboard a B2 and flown over to Ireland, and thence to our office by expedited donkey-delivery , driven by our perpetually-inebriated and frequently-astonished genial postman, Pat. Thank you, good folks at AIC. All is forgiven. By the way, did you spend all my $60 on cold beer? Below is an old photograph of postman Pat delivering mail to our office.. donkey mail.bmp
  11. Sigimund, the obvious is to open the snapshot on another PC, and look if the grid appears.......
  12. 5th of June, God's in his heaven, all's right with the world; except, that is, with my copy of the AIC Guide, ordered on the 9th of May and which, at this very moment, is aboard a tramp steamer flying a North Korean flag of convenience, and making its leisurely (wrong) way along an uncharted and previously unknown tributary of the the Mississippi river. And, to make matters intolerably worse, I've heard that the good folks at AIC snail central have spent my $60 on cold beer.... C'est la vie.
  13. Wow! Sigismund, you are having strange problems.... Are you running the dreaded Windows 8? Seriously, could you post an example? Regards, John.
  14. Sigmund, a further test which might help is to image the surface of the stone with a macro lens at 1:1 or 1:2 magnification with low-angle raking illumination. A single LED flashlight is good for this (unless you have a laser/line generator). You need take only 1 exposure. Open in Photoshop, ImageJ, or whatever, desaturate, apply enough sharpening to reveal structure and examine the result. If it appears grainy, it's your sample's surface. Regards, J.
  15. Hi Marlin, We use several light sources, including small LED flashlights - ideal for very small objects. Our illuminant for the timber was a 100W halogen mini spotlight fitted with an additional opal glass diffuser, which guarantees uniform light distribution. The beam angle is adjustable, we set it to its widest - around 65-degrees. For something as small as our timber sample, we use a simple rig for holding the light in position, so that's not the problem. We haven't experimented with the camera's metering settings. We are currently using spot-metering, but we'll try the others. I'm not too concerned about the problem, as we can use our structured light source (a laser fitted with a line generator) to capture a raking-light image of our evidential sample. However, if we can crack this one, it may prove useful to other RTI users. I'll let you know what happens.Many thanks. John.
