Does anyone here use a Canon 8800f? I just got one and am horrified at the results compared to the Epson V700 I use at my university. Does anyone have any scans that they got from it to share? Maybe tips on how to pull a good B&W scan from it? I was thinking maybe it's just the included software that's crappy.

The hearing aid batteries in question are 1.4V, the original mercury batteries are 1.35V. This minute difference is probably worth about a third of a stop at most and can be corrected by setting a slightly lower ISO. You also get six to ten of them for the same price as a shipped Wein cell. I've heard that Wein cells can last for a few months, but I've never heard of them lasting a year when they've been activated. Rednik: Can you post some of your scans? I don't think a V700 and 8800f are really even comparable scanners, so I wouldn't be surprised at a large difference especially in smaller formats. Maybe if we see some scans some 8800f owners can see if your results are typical.

I'm borrowing my friend's 8800f, just using the included software. The image straight from the scanner was a little flat so I upped the contrast in Photoshop (just curves) and this is what it gave me. It is medium format, so I'm not sure if it would be the difference between doing 35mm and 120.

I don't know, that looks pretty good. That's a seriously contrasty scene, so the blown out parts could just be the way it was scanned. Not bad for $160 or so.

Kaerf posted:Well, yea, for ~$200 what more could you really ask for? That's basically the only reason I want to get one for myself, to scan my medium format stuff to upload to flickr. If I wanted to print anything, I'd either do it traditionally or have a shop do it. Yeah I suppose I'm in the same boat. I'll try it with some negs that I've already scanned at the uni to compare and maybe post them. It could be that the lab that processed my B&W in Eastern Europe hosed up with developing the shots. I guess I just felt too lazy to make the trek to the digital darkroom and make do with the convoluted scheduling of the scan room, so I got the 8800f. Does anybody use or has heard anything for/against 3rd party software? Edit: by the way Kaerf, that scan looks great

Well it's not really a fair comparison. One is a much better scanner scanning an evenly lit image with a lot of detail that is all on one focal plane, the other one, well, isn't. There's no doubt that the V700 is a better scan, but the 8800f doesn't look half bad considering the depth of field at play in that image. And apparently you didn't even use a USM?

You can get 8-bit images (tiffs, jpegs, i haven't tried anything else) to open in camera raw as well. There's a preference for making it the default or you can just choose "Camera Raw" from the format dialog in Photoshop's open dialog when you have the image you want selected. I sometimes do this if I need to do some white balance correction or fiddle with fill/highlight recovery as I find its easier to do in Camera RAW than using more conventional Photoshop methods.

Clayton Bigsby posted:Bad example: all the Spotmatics used a bridge circuit and aren't particularly picky about voltage. You're wrong quote:If you're up to trying, a silver-oxide watch battery can also make a good replacement in a pinch. Karen Nakumura of Photoethnography.com put it succinctly when she wrote that Pentax "built in a bridge circuit in the metering which makes it battery voltage independent," which is to say that a silver-oxide battery of about 1.5v tends to work just fine for the light meter in most Spotmatics without effecting the sensitivity (your mileage may vary, but most people are happy to report less +- 1/3 EV). Gene Poon notes that the Spotmatic 'F' was the exception, because it has a dual core meter that requires a precise voltage, so it's not too good to substitute the wrong voltage. What hearing aid batteries are these? .05 off is 1/3 of .15 volts which seems to cause a small bit of EV change in even bridged circuits.

I don't know what to tell you, but the difference between a 625 Wein cell and a 625 alkaline with ISO halved is really hard to tell. The discharge profile is the only reason to go zinc-air, in my opinion.

Scanning!! I've spent most of the day loving around with this Canon 8800F and I'm wondering if I didn't gently caress up buying this thing. What I have found to work the best for me is to use the Canon MP navigator to make the scan, using no filtering other than unsharp masking. 1200 dpi seems to be the best compromise between detail and image size, going to 2400 seemed to be more useful for inflating file size than detail. Same with 16 bit gray vs. 8 bit, on some images 16 bit made things worse. Also, 120 seems to scan better than 35mm. Color scans better than monochrome. I would scan the image in MP Navigator, save it as a TIFF, open it in iphoto, make my manipulations and export as a high quality JPEG. Anyway, here's what I came up with. 35mm A couple in 120 I dunno, but I may be rethinking my choice of scanner. Not much to be done now, maybe my expectations are too high. I would have been better served my mixing up a can of dektol and filling some trays....some days you just feel like taking a hammer to the whole works and taking up whittling.

Bleh. On the top of scanning, My V500 seems to choke on Kodachrome. It scans, but it seems there are tons of artifacts. It almost looks like bad JPG compression, so I switched to TIFF, with no change. I'm using the Epson software.

Sorry to make this the scanner problems thread, but: These are from an epson 4490, scanned through epson scan at 2400 dpi, 48-bit color, tif format. The film was 645 160VC. The lower part of the image is a full-size crop. Has anyone experienced this? I tried flipping the film around in case of newton's rings, and also re-scanned it twice. Same results. It happened with other frames in the roll as well, but not all of them.

Is it just because they're huge? It's because they're huge and getting dated. People are buying RZ67s instead, even though the RBs are perfectly good. The RZs have a slightly better lens range.

I have the Canon 5600F, which is pretty much the 8800F without medium format scanning. Honestly I've been pretty happy with the results, I turn all the auto adjustments/dust removal/sharpening off and do the sharpening/curves in Photoshop. If I want a good quality image I just scan at 4800 dpi then resample down to between 6 and 12 megapixels. I'm happy to post a full-res sample if anyone would like to see.killabyte posted:Bleh. I remember reading that the infrared beam in dust/scratch removal doesn't handle the surface of Kodachrome very well, maybe check that it's turned off.

Martytoof posted:Can I have your stuff when you destroy yourself trying to find this lens? Nah, but I don't see why you'd want it. None my equipment is particularly expensive. While admittedly, I did get a fantastic deal on my Pentax 6x7 (body, prism, 105mm 2.4, 75mm 4.5 for $1500 AND 40 rolls of tri-x 400 for free), you could get it for about the price of a 5d mk2. I shoot 35mm on a Canon t70, and mainly use a 50mm 1.8, the t70+50mm 1.8 should not cost you more than $160 pretty much anywhere. I use a cheapass Phoenix wideangle zoom (19-35mm 3.5 I think) that I got for 30 bucks, and I got some other Canon telephoto zoom for free when I initially got the camera. All of the mounts are FD, all the lenses are fantastically sharp, and in terms of longevity, I've dropped my t70 and 50mm literally hundreds of times, sometimes in the rain or snow and it keeps on trucking perfectly. That camera is pretty much indestructable.

I tried the same frame with no ice, ice-speed, and ice-quality. Of those only ice-quality exhibited the streaks. Ice-speed messed up some details though so I probably won't use it. Backlight correction on medium and high with ice-quality yielded minor streaks on the edges. So yeah, the only thing that worked totally was leaving ice off. Good to know the scanner's not defective.

Dead-on exposure, nice and sharp lens, you can run it as low as 1/15 handheld and I got 39 photos on a roll of 36 without trying. All the hype about this camera is for real.
