I am not a physicist. In practice, I find the outer edge of the Image Circle on the 72XL grows a little when I stop down. And the filters I use at the edge of the mechanical vignette at full rise or...

How does that work? Are you saying if you use a small hole you only use the middle of the glass?

I use PS mobile to invert the image if I want to see it on the phone, I just set up a 'theme' that inverts. I have started to use the Tech Camera app to capture the negative as a grayscale DNG and...

I used the Lee holder you reference on hundreds of photos until the markings of my 72XL started to wear off. (Not really a problem but an annoyance, since the Lee holder mounts with a tension ring...

That reminds me that if you tear Kodak's internal sealed paper film pouch instead of cutting the sealed end with a pair of scissors or razor, then the torn paper edge will create dust particles. The...

This is an interesting subject. I have never used the raised dots, because I set up my film loading area in the light room. Does anyone use the raised dots on a regular basis instead of in theory? I...

True, but if you're just starting out and can't take a class, it's nice to see the unseen.

UMBRELLA: I use it for a lens shade, rear sunblock, top shade for me, and sometimes I'll hand-hold it sideways as a wind block. It is a "Sport-Brella Versa-Brella" (Amazon again) with a custom copper...

On camera, I use a "11"inch tablet/reader" pouch with a loop sewn on the corner that holds three holders while I compose and focus. This keeps the holder in darkness, out of direct sun while I take...

We might as well make this a useful post for beginners learning how to shoot 4x5 so if you have any other tips related to holders or best practices, send then in.
I use Gallon size Ziplock (or Glad)...

That is correct. I was taught that at school too.

But the label color is arbitrary: the slide and film don't care. Since I didn't apprentice with any 4x5 shooters, the tradition hadn't been...

I created this How To video for some of my students who wanted to know how I have been loading 4x5 and 5x7 film holders for the last 30 plus years.

I may not have mentioned at the start, that the trick with scanning my 4x5 and 5x7 HABS negatives (the ones that get submitted to the Library of Congress) is that the entire negative and rebate edge...

Interesting techniques. It looks like my notice/subscription to this thread got turned off so I haven't seen the last few posts until today when I posted a new thread on iPhone quick-scanning in a...

I thought I'd start a thread about scanning negatives with a phone camera. I have an iPhone 13 Pro and the Macro mode seems to leverage the extra wide lens and has good sharpness in the center but...

I'm still doing mostly Large Format 4x5 and 5x7 HABS/HAER/HALS photography for 80% of my income. Architecture, engineering and cultural landscape documentation that is ultimately delivered to the...

This is a great HABS image by Marvin Rand he did around 36+ surveys for HABS. There are HABS images by Julius Shulman (LA City Hall) and even Balthazar Korab but their names are not always keyword...

Adam, your camera has a rotating 4x5 back that adds to the distance inside the camera. If you get the non-rotating 4x5 back you'll gain a few millimeters. Bag bellows will definitely help. If you...

Here's my heavily modified HABS-HAER-HALS camera with a front standard that utilizes the NEW-style double lock knob on the side and the shift lock from an even older 1960s era SuperCambo with the...

BTW, one on the (many) cameras Julius Shulman used was a wide angle version of the Calumet 4X5 CC402 (with spacers offsetting the front standard rearward) Like this one at KEH:
213463

OR you can go wider if... you can get your hands on the OLD Cambo "double lock" standards.

That's what I have on my 4x5/5x7 Cambo custom HABS camera. Since a large proportion of HABS/HAER...

Glad you liked it. It works well for me and it's very fast compared to scanning on a flatbed. I'm sure there is a point where a scanner would show a better result, but I imagine that is somewhere...

That reminds me of a quote I did to HAER photograph an old 1950s classified thing that was being demolished at Lawrence Livermore National Laboratory, it was also classified, and the week before the...

Hi Kirk,
I recently did a 5x7 job in downtown San Francisco on a reservoir that was also overkill. But once the mitigation language is written into the Memorandum of Understanding, there's no way...

Hi Terry,

Like Jason and Willie said, you could use a meter, but I haven't used my meter in five years. Since it's HABS/HAER, and you are being paid for the service, and you need to produce 20+...

Just saw this question today. Emulsion down to avoid Newton rings.

I got a 120mm "Wollason Meniscus lens" from Reinhold Schable in Washington. I'll send photos soon. It's a very simple clean setup. I need to mount on a Cambo board and experiment.

That isn't the soft-sharp I'm looking for.

No the edges can be wonky. It might be something that gets repurposed from 6x9 or 6x12 medium format. Or even a lens without a front or rear element that exhibits a certain funk.

What's the widest soft lens for that covers 5x7? Or 4x5 with movement. I'm toying around with doing some photos that are the opposite of documentary HABS super-sharp, maximum depth work. I used to...

That sounds like a good one.

Have you taken a Large Format camera workshop or know of one? I haven't taught one in a few years, and I'm just wondering if everyone's gone virtual/digital/youtube. (Tempting)
A quick search of...

Single photos, since the offline (old Mac) system is not color calibrated and all settings are zeroed, I choose from the three bracketed exposures back at the studio on the iMac Pro in Lightroom...

Come to find out, it's pretty hard to find a place to host big 13MB DNG files (they are compressed DNGS). After figuring out my Adobe creative cloud online storage, I was able to upload the full size...

I'll have to order a Kaiser CD pen and give it a try. Any idea if it is dye or pigment based? I can't find an MSDS sheet or anything specific except the Kaiser marketing materials.

I thought this might be of interest to those people searching for markers to number negatives. I've used many pens doing Historic American Buildings Survey photography. The requirements for marking...

Indeed, to Sal's point on page 1.



I do HABS/HAER/HALS and digital scanning is in the guidelines. So those (few) HABS photographers have a choice of contact prints or scans and "digital print...

I thought I would share my system and equipment for scanning 4x5" and 5x7" negatives for HABS/HAER/HALS. (definitions here: HABS LINK)

I took a column from a Beseler slide duplicator and added a...
