I checked the higher shutter speeds on my Angulon. Actually, mine are 1/250 and 1/500, not 1/200 and 1/400. I am not sure why I had 1/200 and 1/400 in my mind. Anyway, I used my shutter tester and...

Larry,
No, I don't want to CLA any shutters belonging to anyone else! I don't want to risk damaging anything that isn't mine.
To test speed, I made one of these shutter testers:...
I was given one of these last year and CLA'd it myself, so I learned quite a lot about its workings. As was mentioned by Corran, the highest speed setting is harder because when you turn the ring to...
StoneNYC, the diffusion effect in that image is subtle and doesn't look excessive or distasteful as it does in the kind of image I am criticizing. In fact, I am not sure you used a filter on that...
It is too bad people are so uncomfortable with how they actually are! I wish they could see themselves through my eyes. I love wrinkles. They display a person's character, and that character is so...
I made one of these and it works great as far as I can tell:

I tuned up some old synchro-compur shutters with the help of this device...
That's comforting! I am one of those OCD nuts who obsesses about that one nearly microscopic little speck I can't seem to get off the glass!
As for all this vaseline stuff, frankly, I just...
Lenny,
I thought I have made it clear in numerous places that drum scanners are CLEARLY superior at higher resolutions. But at 2400ppi, the differences aren't huge. In fact, they may be hard to...
It might be better, but it won't scan sheet film.
Here's another fix of a V750 scan on that comparison page, this time of the overall color. I tried to match the Aztek scan fairly closely, but...
Here's another one. The V750 version from the comparison site is here:
89411
The Aztek Premier version is here:
89412
And here is a modified version of the V750 scan that I sharpened and...
The images on that scanner comparison are at 2400ppi. You can't see the zig-zagging at that resolution.
But that scanner comparison page annoys me. Even as much as I dislike the V700/V750 in many...
Velvia 50 with these scanners is a known problem, worse than any other film I know of to scan. You quite simply can't see everything in the shadows, no matter what you do. The dark shadows on a sheet...
Yes, that holder with anti-newton-ring-glass would certainly be better for holding the film flat. I am surprised that you feel that you need to get the included plastic holder closer to the glass...
I took your sample into Photoshop and placed it right next to a scan from mine at the same resolution and my results are pretty much the same. And it doesn't seem noticeably worse at 4800ppi than at...
Here are some screenshots showing the settings I use:
8936989370
Also, if you press the "file save settings" (has a folder with picture icon) button, next to the "scan" button, and then press...
StoneNYC, I suspect that your scan with the regular holder could be improved some by adjusting its height a bit. It looks rather out of focus to me. It has a lot more CAs than I normally see as well....
Thanks for the examples. Here is a sample of my own, scanned on a V750 at 4800ppi, resampled to 3200ppi, and sharpened liberally. This is from a 4x5 sheet of Portra 160, shot with a Schneider...
Earlier, I made some disparaging remarks about ColorPerfect. I didn't mess with it for a while after that, but last night, I solved my problem. I had apparently messed up some settings and after I...
StoneNYC,
I have adjusted the holder in very small increments using paper shims, looking at only one tiny spot, and moved through a range, making sure I went from unfocused to ideally focused to...
What resolution are you scanning at? You cannot possibly get sharp pictures at the resolutions advertised by the manufacturers. They are liars. The highest resolutions where you can get reasonable...
Are you scanning the film? Why not reduce sharpness in Photoshop? It is very easy to reduce sharpness and have complete control over it. You can do some blurring on a duplicate of the image and blend...
You could always try designing and grinding your own lens. Even if you try your best to do it all perfectly, you are sure to get plenty of character in that lens, and you'd have extra bragging rights...
Nathan,
Did you mean to attach or link to an image here? If so, I don't see anything.
Why would a collimated light source make a difference? I genuinely would be interested. I know that the...
To help calculate exposure compensation for bellows extension, I just bought a cheap, super compact plastic tape measure from the sewing isle and then used the appropriate formulas to mark it for...
I have an Arca B1 and use it sometimes with my Toyo/Omega monorail. It seems a bit light for my monorail. I can't really set the minimum friction setting tight enough to make sure I avoid...
I only had a semester of organic chemistry in college, and I forgot most of it, so I am no expert, but it seems to me that naptha alone wouldn't be such a different substance from naptha mixed with...
Okay, I was reading through the thread that scm linked to. It seems it does address a lot of what I am getting at. Maybe I should read that. If a moderator wants, my posts in this thread could be...
scm,
Thanks for the link. I'd kind of like to start a new thread though. As I'd like to explore the idea of trying something perhaps a little different than the usual DSLR idea.
Anyway, I...
Here is a video about the ARGUS sensor on the drone. It is pretty astonishing.
https://www.youtube.com/watch?v=0p4BQ1XzwDg
This made me think that maybe small sensors are the way to go for...
Drum scanners are old technology. And film scanners like the Nikon Coolscans have old CCDs in them. And most the flatbeds are pretty old tech.
You'd think that with all the amazing advances in...
Yes. It is true. There are reasons. Film handles bright things more gracefully. And it doesn't have that bayer look that I so despise. A 4x5 camera, some lenses, and a decent scanner can be had for...
Oh, how I wish it was! It is worse than you might imagine possible. Scanning and processing is the part that just destroys the romance.
I was just playing with some negatives last night, even...
BenTotman,
About your decision, if you like film and that's the reason, good. Just realize that doing things this way hardly avoids the headache of digital workflow, with color management...
Here, the vibration effect is rather apparent on this page:
http://www.photo-i.co.uk/Reviews/interactive/Epson%20V750/page_2.htm
I have tried with different software and it makes no difference.
On top of that, which I should have mentioned, you get uncorrectible chromatic aberrations with the Epson scanners. The information in the different color channels doesn't quite match up exactly....
Zaitz,
Do you actually get good results doing it that way in Photoshop? Can you replicate the color and tone you get from ColorPerfect like that? I can't, no matter how much I fiddle and try to...
I second the ColorPerfect recommendation. Just scan the negative as positive with no adjustments, making sure it isn't clipping anything. Scour the settings to make sure you are getting a 16 bit TIF...
Actually, it seems I was wrong about my monitor. It only supports up to 8bits per channel, even with DisplayPort. Apparently, even the ones that support deeper color only support 10bits per channel....
With respect to the banding on monitors that isn't in the file that was mentioned, I'll also point something out that I wish I had known before I selected a video card. The DVI interface does not...
The thing about depreciating digital gear though is that even if it depreciates, it still does what it did when you bought it, at least until it fails. I have an old Canon 10D DSLR that is worthless...
