View Full Version : Imacon 343

In past scanner threads in this forum some users have suggested that the Imacon FT343 (medium format scanner) can be used on 4x5 sheet film. i.e. by scanning the sheet in 'sections' and pasting in Photoshop.

My question is whether the scan path of the 343 is big enough to scan 4x5 without cutting up the film. None of the references I have been able to find are clear in this.

I did call the local scanner dealer (Glazers in Seattle) and was told that the 343 scan path will not accomodate 4x5 sheets and I suppose he knows what he's talking about. Can any of the cognoscenti here second him on that?

Are there any ANY medium format scanners which could accomodate 4x5 film?

Thanks,

Wm T.

Flextight 646

Flextight 848

both handle film to 12 cm wide

Just order the 6x12 holder and scan the 4x5 in 2 seperate passes. You can then put the images together in Photoshop or another package like Panavue.

I haven't done it myself with my 343. I normally have my 4x5 scanned on a collegues Imacon.

You can absolutely scan 4x5 on the Imacon 343- I have. Further more, I've scanned 4x5 Polaroid Type 55 (with the rough edges) and 4x10 on the 343. One does not have to cut or chop the film to do so. For conventional 4x5, the 6x12 film holder is used to scan slightly more than half the film. For the next scan, just shift the film over to do the other side. Part of the film does stick out from under the magnet, but not beyond the edge of the holder. When scanning 4x5, the magnetic wheel that guides the holder into the scanner does ride on top of the film itself, but without any scratching that I've noticed. For larger films like Type 55 and 4x10 I used the 6x17 holder.

If you are doing mostly, and many 4x5 scans, I'd recommend a scanner that will do 4x5 without the stitching-it's alot of work. If one does mostly MF and smaller with some 4x5 scans, once in a while, I highly recommend the Imacon 343.

Thanks all for the feedback.

Looks like I will have to chide the Glazer camera tech for his misinformation.

Think again. He wasn't misinforming you at all. The scanner isn't designed for 4x5. Yes, it will do it. Say he suggests you do the method above, and the edge of your irreplaceable neg gets trashed... you will go to the store screaming about real 'misinformation'.

I bought the Imacon 343 back when I thought I would never go beyond medium format and I have just started with large format. ;-) Can someone recommend something I could put under the film to avoid trashing the negative if I try to scan in two passes, as has been suggested. I guess the material would have to be very thin and protective.

George,
Which stitching software were you using to do the 4x5 work? How were the results? I really don't have the space for a flatbed scanner and bought the 343 because of its tiny footprint. I want to be able to get away with scanning 4x5 on it. I'm not sure anyone ever answered the question as to whether the optical path would support 4x5. If you took the 6x12 and cut it for 4x5, would it work?

Larry,

The optical path of the 343 does not support larger that a 56mm (MF) width. So, do not cut any film holders for scanning LF films. Just use the 6x12 holder and shift the film between scans. I use Photoshop to assemble my scans. Notes: Since my original posts I have acquired a Creo IQSmart 2 and do all my LF scans on that. Also, I did have a custom holder made, by Imacon (now Hasselblad), for scanning 35mm negatives - I wanted to show the sprockets and unexposed edges of film for artistic purposes and since the aperture of the holder was still smaller than MF it was not a problem.

George,
Thanks for taking the time to reply to this old thread. So, in your opinion, is the threat of scratching my negative overrated? The negative will be on top of the metal plate when it is scanned in this way, which is why I'm wondering if some kind of tissues paper could be put down to protect the negative. What do you think?

That Creo looks like a nice rig, but not cheap by any means. I would like to get away with using the 343 if at all possible. Were the stitched results perfect?

I'm curious as to how your custom 35mm holder is holding onto the film, If the film is slightly misaligned, sometimes I get part of the sprocket holes and like the effect, but your holder must be holding onto very little of the edge of the film to give you more of the holes. How much bigger did they make the opening?

IMHO, scratching typically come from some type of back-and-forth abrasive action. Since the metal portion of the holder always touches every negative in some way, it is a non-event. Therefor the only consideration are the wheels on film issue, which is not a a back-and-forth action, just a rolling one. That said, I haven't noticed any scratches as a result of scanning LF films with a 343. If it was still a concern, one could do multiple scans with a not so nice negative and examine it closely for damage, before potentially sacrificing an important image. Perhaps some type of thin photo tape could be applied to the negative to keep the wheels from touching the surface...

My custom 35mm holder is only slightly larger than the image area - to show a bit of non-exposed areas plus a small portion of the sprocket holes - just like a filed-out holder for an enlarger.

So, I have been scanning my first few 4x5 shots and think that I can get away with using the 343, especially after seeing the cost, size, and weight of the Scitex scanners. My first two results can be seen on the last page of this thread: http://www.largeformatphotography.info/forum/showthread.php?100858-New-to-4x5-photography-just-bought-Wisner-camera-advice-appreciated/page5 I am using the Automate>> Stitch function in Photoshop to put the two pieces together. I scan half the negative and then just flip it in the 57x180 holder to get more than half for the other scan.

I started out scanning at 3200dpi but that seemed like overkill so I have dropped to 1600dpi. 1600 and 3200dpi are native resolutions on the 343.

If anybody has other hints on how I could improve this process, I would be happy to hear them.
