I'm pretty sure that image #40 (The Ball Player)on this page: https://www.spiritsofsilver.com/galleries/historical_processes_albumin_cyanotypes_kallitypes_uranotypes_and_van_dykes was taken with the...
I've been looking at the Feather Touch but it doesn't appear to be electric. In fact, it appears exactly like the focuser on my AT115edt. Expensive sucker, even used. The weather forecast here is...
Compose your shot and then, before inserting the film holder, look through the lens. If any part of the bellows is intruding, you'll see it. If you see all 4 corners of the GG, you're set.

I've been thinking about an electric focuser for the SCT. The OTA w/Losmandy DM-10 dovetail weighs in at 29.2 lbs which is .66 of the mounts payload. I'm trying to keep the total weight ≤ 33lbs. ...
Thanks for the reply Steve and the offer to provide instruction. I'll send you an email when I get the camera and need help. Besides the 2600, I'm also considering the 183, 533, and 294. The...
I'm just starting to consider dedicated astro cameras and need to take a deep dive into their pros and cons as I know absolutely nothing about them. OSC is more budget friendly but I am more...
I bought a 26" x 16' box of Bienfang release paper years and years ago from a local camera store for $50.99 which I thought was on the expensive side. Release paper last forever as long as you don't...
After blowing off the big particles with a ear syringe, I cleaned the corrector plate on my 10" telescope with 91% Isopropyl alcohol and a ton of Kimwipes making very light pressure circular passes...
Steven, are you still doing astrophotography with that AP refractor? I just purchased an 115mm triplet and plan of starting with film and if that doesn't deliver what I am looking for in B&W then a...
I looked at your images and come to the conclusion that you are too close with that lens. Take a look at image # 41 ("Sunday Afternoon...") at...
This video presents the best tutorial on properly focusing the view camera that I have come across: ...
Maybe not "essential" but the sheets will not dislodge with the clips which occupy a little more geometry than the ridges. Place them about 1/4 way down and the sheet(s) will "snap" into place. ...
I use the Jobo 2830 and 2 sheet spacer clips placed diametrically opposite on the ridges for processing 1 or 2 sheets of 8x10. The clips keep the sheets from moving around during processing and...
This an image of the coast line as seen from the Gulf of Penas in southern Chile (Patagonia). It’s one of my favorite images which I published in the Color Landscapes gallery on my website. Just a...
I may be wrong in this, but I think that all you would need to go from 4x5 format to, say 8x10 with the ROBOS would be an 8x10 rear standard, bellows, and probably the G type tripod clamps. The...
I've had this lens for 810 format for 20 or more years now and had SK Grimes build a 120mm to 95mm step down ring ($150) so that I could use all of my 100mm rectangular filters with the lens in my...
None of the prints shown in the Salt Print Gallery on my website have shown any fading or discoloration since they were printed 10 or more years ago. In fact the second print in the gallery sits...
The heaviest lens that I have is probably a 14" (355mm) Wollensak Veritar which is a front mount lens. I use it on the Toyo 810MII and 810G and no sag occurs because no extreme extension is...
For extreme scene contrast try the split grade printing technique and Defender 59D print developer. I recently revisited such a negative that I couldn't get a decent print from in the past and got a...
I use little plastic salsa cups https://www.webstaurantstore.com/choice-2-oz-clear-plastic-souffle-cup-portion-cup-pack/999P2C.html that I got from a local El Pollo Loco for measuring out small mass...
The hardest part, in the dark, is finding those pesky little rails that the film goes under.
Agreed. It's even harder with 8x10 film because of the size of the sheet. What I do is to put an...
I'm using an iOptron tracker equipped with a zwo autoguider and phd2 so very long exposures of several hours are possible. The tracker allows for slow motion adjustments in right ascension so you...

This platinum-toned kallitype print was shot with the 610 apo-Nikkor at f/32, 1/8 second. I focused on the eyes/nose.
See https://www.cloudynights.com/topic/436086-large-format-astrophotography/ for example.
I also have a 300mm f5.6 Nikkor-W which weighs in at 1250gms. The combined weight would still be within...
How do you plan to keep your film flat during such long exposures, Tom? Vacuum holder?
Not right off, Drew. All of my 4x5 holders are Toyo's and I am initially going to try without modifying one...
If your camera isn't already equipped with it, a Fresnel will aid focusing immensely.
I'm planning on doing some wide field astrophotography with it mounted on a Toyo 45CF w/Fresnel.. The...
Also not the case on the MII.
If you are processing multiple sheets at a time, consider carefully Kodak's recommendation for processing time:
Using Full-Strength Developer
Choose the appropriate table for development times...
I recall a wheelchair-bound amateur astronomer attending star parties with a 16" Meade SCT and using a hydraulic lift to off-load the OTA from his van. The OTA of the Meade weighs 300lbs and the...
You also need a set of print/film separators. These are small cylindrical tubes that slide into the raised ridges on the 2830. Place them a couple of inches from the top and directly across the...
It appears to be taken from the Areopagus which overlooks Athens and is downhill from the Acropolis. I have two views taken from there on my website. If you go, be very careful of your footing for...
I've been using 8x10 exclusively for alternative printing (salt, kallitypes, etc) for 10+ years now. But recently I started back printing silver gelatin using Ilford's 5x7 Satin RC paper and am...
Check and make sure that the holder is firmly inserted all the way - I have a hazy recollection of not having fully inserted the holder when I first got my AX. Keep a thumb on the edge of the holder...
I was lucky - my most favorite turned out to be the very first LF lens that I bought, a 150mm Apo Sironar-S. I bought it based on the lens, true or not true, hype that was going around at the time....
It looks like the right hand side cold have been trimmed a couple of mm bringing it even with the first post on the left. But that would leave part of the first truss cropped out. An in-camera...
I took this image 8 years back when returning from a trip to Yosemite. I parked the car on the roadside and walked to the bridge to check it out. It looked appealing so I decided to shoot it to...
Focus on the far, tilt for the near....do that until both near and far are in focus. I believe that is the recommended procedure for cameras with front base tilt which the MII has and the direct...
Unfortunately I didn't record the exposure for this negative but the film was either Acros or Delta 100 with a 360mm lens. However I did photograph it on a different day with a 4x5 on Tmax 100 with...
If you keep both standards parallel, then you can't get a plane of focus that encompasses 3 or more points. In the print below I wanted the house and the immediate foreground grass sharp so, IIRC, I...
