Just incase anyone is thinking of ordering one of the tiger ADP-5501 power supplies to use with the staticvac, the wiring on the plug is reversed from what it needs to be, so you may want to look for a different one. I'm working on resoldering the socket on the staticvac right now (had to take it apart to clean it anyway).

Thanks for the heads up. What is the pin-out on the power supply and what needs to be switched?

Here is the pinout for the Kinetronics 402


And for the Tiger ADP-5501


I wound up taking the power supply apart and switching the white and red wires going from the plug lead to the board to reverse the polarity of the pins. Had to remove some hot snot with an x-acto knife to get the wires off the board.
Since the static vac expects those top 4 pins to all be unconnected and two of them were still getting power from the brick, I wound up having to cut through the traces on the static vac's board as well. There are traces on both sides of the board so I drilled entirely through it to get both.

Seems to be working well now. Whoever the previous owner of this thing was must have never cleaned it, the inside was like an old computer.

Well, my V600 managed to last almost exactly 6 months. Using this as an excuse to pick up a new scanner. Any reason to get the v850 over the v800 besides the extra film holders? Seems like the v800 is a much better deal.

I read somewhere the v850 has coated optics but not sure if it's BS or what. I have been considering picking up some v850 holders to use on my v700 because they are super cheap for adjustable AN glass insert holders.

Every time I think I am going to try to find a faster way to process scanned negatives, I try out all the different automatic software offerings, but in the end I come to the conclusion that scanning a "raw" positive and making the RGB levels adjustments manually in photoshop gives the best results.

I also found that when applying the final color balance with curves, I can save the curves values as a preset and apply them to the rest of the roll with a single click and it seems to give consistent results. It is really easy to find the correct curves value by processing a negative that has something grey in the scene, then using the midtones eye dropper tool on it (from the curves dialog box). Concrete usually works well. Then the same curves can be applied to other shots that may not have a grey object to measure off of.

I wonder if these curves can be applied to all future scans of the same film stock? Or would there be slight variations depending on the age of the film and the age of the chems (assuming home c-41 development?) I guess I can experiment.

In my experience, there's also variation because of light temperature/tint and over/underexposure. I used to use actions I'd made to apply to every scan on a particular film stock, but if the exposure or lighting wasn't the same, I'd end up doing some curves work anyway. At that point it makes more sense to just work on every negative individually.

I'm sure if you can define a baseline curves adjustment then any further tweaks will be a lot simpler than processing a raw positive each time. I know people on the Pakon Facebook group have had a lot of success using the ColorPerfect plug-in, so maybe try that also? http://www.c-f-systems.com/Plug-ins.html

I have tried the colorperfect plugin, and it's given me the best automatic results, but it's currently $92 CAD and that's more than I want to spend on a photoshop plugin right now (or ever) considering this is ultimately just a hobby.

I used ColorPerfect on the drum scanning station I rented a few years ago and while the UI is far from intuitive, the results are pretty loving good. On the other hand, yeah, why spend money when curves work?

I've got a bunch of 35mm negatives and the usual stacks of my family's 5x7 prints, so I'm looking at scanners. I could get a refurb V550 on Amazon for $110, or a new V600 for $205 (no refurbs on Amazon or Epson). My priority is for the 35mm, with the print scanning as a nice extra. I'd also like to do 6x6 at some point but that's later since I don't even have a camera for it. Refurbished V550 seems like the straightforward choice; is there any really good reason I should get the V600 instead?

Oct 30, 2010



Double-posting is lame but whatever. Surprise, I bought the V550. Goddamn there's a lot of dust on my negatives.

I blasted them with compressed air and hit the scanning surface with it too, but even after removing all the worst big chunks of dust with the content-aware spot healing brush I still get this:

That's considerably more than what I usually deal with. Get an anti-static cloth and wipe them down before blowing the dust off, and it should keep most of it away. And try to keep movement to a minimum in the room your negs are hanging in, otherwise you'll get dust stuck in the emulsion when its wet and they will be impossible to blow away once its dry.

gently caress, I've been forgetting to run the shower before hanging negatives lately.

I might have dust stuck to the emulsion. Can I get that out any way, or should I resign myself to lots of Photoshop and just make sure to run the shower before hanging negatives in the future?

Put a drop or two of Foto-Flow in some warm water, immerse the negs and run them through the pad of your thumb and index finger under water (avoid fingernails at all costs), then hang to dry in a non-dusty environment.

For editing, I will a lot of times just select the out of focus areas with the lasso and hit them with Dust & Scratches if there's a lot of junk there and I'm not printing big. For a "hero shot" I will spend time individually spotting stuff out... a graphics tablet makes a massive difference in terms of reducing the tedium involved.

If it's colour stuff that's not gonna be seen above web res, digital ICE isn't bad, but I really regret scanning my nicer stuff with it on and am going to have to go back and redo them someday.

Don't hit the scanner with compressed air. It will just make the dust fly around and might even increase the amount that eventually end up on the scanning surface. Use a microfibre cloth or something similar for cleaning the scanner surface.

Different topic, after scanning a print how do you guys pick it back up off the glass? Stick your fingernail under a corner and lift, or push it to the front of the scanner so you can pick it up without contacting the glass?

hey scanner nerds, i need some tips about Silverfast

I just spent about an hour pulling my hair out trying to figure out how to simply get an un-molested negative scan out of it. I'm using SilverFast 8.2 and the issue I was having was with it's aggressive enabling of magical curves and auto color correction. I'd use Epson Scan except it literally wont scan my 4x5s at the 2400dpi @ 48bpp, and stitching two separate overlapping together works "ok" but SilverFast seems like the "right" solution.

In order to get SilverFast 8.2 to just do what I wanted, I had to expand NegaFix, reset to defaults, disable CCR, expand expert settings, disable Auto, make sure Vendor and Filmtype are "Other" and that ISO/ASA were set to <Linear>

Only then did I seem to get a non-hosed up scan. Does anyone have experience with this? Is there a better way?

edit: I should note that i'm still frustrated that I can't get a mostly untouched scan, the above steps are a big improvement but it's still unmasking and still clamping color before giving me a "48 bit" scan (which is just 48 bits after software interpolation in Silverfast, which i want less than just the full 48 bits out of the scanner)

If you scan as negative it'll always gently caress with your curves - that's why you should be scanning as positive.

I picked up a cheap V100 and started playing a bit.
While it's far behind what I see posted here in terms of image quality it lets me play around with curves and color rendition, and maybe decide if I'd like to go all in later for a more recent model.

My only complaint is that the scans lose lots of details, which seems more like a focus thing than a limit in resolution. Is it something I'll have to accept for now or is that what the betterscanning holders are for ?


e: I'm scanning 35mm negatives
e2: betterscanning doesn't have V100 models, oh well

It also produces a lot of weird little artefacts you can see at 100% zoom. For smaller web-res stuff it's OK and a timesaver over spotting out dust and scratches, but for archival or printing purchases I would recommend turning it off.I had a huge (80+ rolls) backlog of scans and used Digital ICE on almost all of the colour stuff, which I now regret.
