Why? Well printed plastic is just as durable as a fidelity holder. Possibly more so.

The thing with ball heads is that the vast majority of them are mildly terrible, in that they're either "locked" or "free", with very little in between.

I've got one that actually has differing...

Not sure-- I've got an AMD 8/16 core system with 16gb of RAM and my working disk is a 500gb NVMe SSD. It does pretty well on high-resolution stitches of medium format, but I haven't thrown a 7000...

Memory and high speed disk are going to be more important than CPU for a task like stitching very large images together.

As has been pointed out, Freestyle, Photographer's Formulary, and Adorama, don't have these issues.

Someone at B&H just isn't interested in putting the work into it.

Several months ago, I...

The 24-70 f/2.8 L is a nice lens, but it does suffer from a small amount of distortion. Compare with the 100mm f/2.8 macro:

Please define "not as good"-- it's a terribly vague term. There's a lot of FUD and misunderstanding about the Epson scanners, and vague terms don't help.

Some technical bits:

There are two...

Even the "low-res" lens should hit 2400 PPI, so printing at 300 DPI, you get 8x enlargement. 600 DPI, 4x enlargement.

You have the opposite problem. The camera is taking pictures fast enough that some elements are on, and some elements are off-- more accurately, the different elements have been on and off for...

I think I grew up near there. :)

North Florida has some odd place names, mostly from local Indian names. Chatahoochee, Sopchoppy, Ochlockonee, Steinhatchee-- and then there's "Two Egg" (no,...

Well, yes-- any light source using direct AC is going to flicker. Get a decent DC power supply, and run the LED's from that.

Or just get a decent LED lightbox.

It is a slightly odd oversight. It wouldn't be that hard to fix, either. I know square aluminum tubing is easier to source than t-slot extrusions, but the t-slot would allow for either a gear...

A friend of mine intends to build one, and has the download. In theory, I should be printing the 3d printed parts "soon" for him (I have the next couple weeks off).

It is difficult to find anyone...

You're not trying to do extreme closeups, so moving the lens a bit won't affect things noticeably.

Even at 5 feet, the change in magnification will be tiny-- a 210mm lens has a focal length of...

It's one channel, 16 bit, so 2^16.

Here's a "non-technical" explanation-- I am not an expert, so if I get anything hideously wrong, feel free to correct me, but as I understand things:

A color space, in the simplest terms, is the...

Depends entirely on the camera, but in general, yes, this is correct.

The rough side of the ground glass is the focusing plane. It should be the same distance from the lens as the film plane when...

They're very pretty, although the 3D printed ones aren't quite as nice looking in my opinion. But I would strongly suggest you search the forums for posts related to them-- I've seen a number of...

Not sure, but after testing scans at all of the height settings, I settled on the 2nd notch-- the one with the arrows. So perhaps that's what Epson calibrates for.

With all respect to Vaughn, I don't think you can fold up the F2 with the front standard screw facing forwards-- well, you can, but you'd have to invert the front standard every time you set it up or...

The Epson will produce consistent results, without too much effort. Not to say there isn't a learning curve, but once you establish your preferred process, it's easily repeatable.

Scanning at...

Ya'll need to be careful... One or two responses almost contained useful information not wrapped up in dogmatic hyperbole. :)

To the OP:

"apochromatic" is a term which is supposed to...

Fred Newman put out a video on camera movements several years ago, and it's one of the best I've seen: https://www.youtube.com/watch?v=0JU-eHpk97Y

His recommendation is to focus on the near, tilt...

Also, since this site by and large doesn't handle "confidential" data, it might be worth modifying the HSTS policy to be a little less draconian.

I understand the "strict enforcement of SSL", but...

So maybe it should be posted to "Still Life"...?

Florida joke:

Q: "Why did the chicken cross the road?"

A: "To prove to the opossum and armadillo it could be done."

Don't worry about it too much-- it's an unusual issue for a specific model of camera that for basic use, shouldn't be a problem. IF you have a heavy lens, and IF you have the base board angled...

There's a list of Compur serial numbers here: http://camera-wiki.org/wiki/Compur_serial_numbers

According to this list, 715688 is 1925'ish. The shutter serial number should be on the outside...

Do a regular package update if you haven't recently. I tend to forget not everyone running linux knows linux. :)

Which browser? I'm on Linux (KDE desktop under Manjaro) with Chromium browser, and they show up fine. Just checked firefox as well.

You might want to see if you have an update pending for any...

You didn't specify color or black and white.

I would check out the Raleno PLV-S192-- it's an inexpensive LED panel designed as a fill-light, but it works well (and is pretty commonly used) for...

FYI, the replacement pack held up fine. Although I didn't let it sit around as long-- I "repackaged" into a vacuum sealed bag.

45N-1 (Classic) owner here. It's very well made, well designed, beautifully built. The only real complaint is that the front standard has to be taken down and put up when you use it-- but that's...

I overexposed a shot by.... a lot. I'm guessing about 9-10 stops. When I pulled it out of the fixer, I thought I'd screwed up the development, but the other two negatives were fine.

Was able to...

It's not the lens. Focused to infinity, you'll usually be at 150mm between the central point of the lens assembly and the film plane. The closer you get, the more distance between the film plane...

Rushing doesn't mean skipping steps in your process. It just means proceeding at a deliberate speed. If it's bright and you need such a shade, attach it before you compose / check focus.

Every...

I admit total ignorance of all things Gowland... but are both the ground glasses oriented the same? ie, frosted side towards the lens (or not) on both assemblies?

Silverfast SE Plus and higher (available at a discount for Epson v800/v850 owners) have the multi-exposure option available which theoretically extends the dynamic range of the final image.

At...

As others have said-- you're using practically no rise (in fact, you're using a bit of fall) on the front standard. Level the base, set front and rear to 90, and raise just the front standard. A...

Well, that describes a light leak pretty well, and one related to the back of the camera (since that's the part that changes for landscape). The fact that it's consistent across the entire negative...

I had to find the quote that backed up what the random synapses were trying to tell me:



Vuescan is probably doing this with the RAW data from the scanner, but a resample using bilinear...
