Good point. I have done just that with my most used filters. I guess my point was that there are those who will use your filter factors as they are listed on the app as being totally correct. ...

Thanks for all the work on this very useful app. Since you are using Filter Factors to determine the exposure changes, it seems to me that the FF for the polarizers should be between 3 and 4, not...

I had the same problem with a much bigger tripod/head combination. I finally fournd one with a folding "camp chair" inside of it. It comes with the bag! I found it at REI although I suspect that...

Thank you for sharing the beauty of Yosemite with others. The video provided a small glimpse of what to expect and it looks like you all have captured the spirit. On the video you guys all look...

For the few times when I have used all the rise I can and the bed still interferes with my Lee filter, I have done what Will is proposing....position the camera so that the bed is at a 90 degree...

If you are dropping the bed to accomodate the longer Lee graduated filters, you may want to try what I have had to do in a similar situation. Although I do not have a Tech IV, I have turned my Toyo...

Arthur....Although I haven't tried it yet (I also have the same Imagon lens w/ the press-fit ND filter and the same problem) there is a Hoya Polarizer Filter Set that is designed to fit over ...

Paul....I always put the grease on the emulsion side, the dull side. That's where the silver halide crystals are located. Not sure if there's a logical reason to this, but it does work. Best of...

When I worked in a photo lab before the days of Photoshop, we used the grease from ones nose to spread on the scratched negative....similar to what Doug and John are doing. It worked better than...

If you're not in need of the money, I would definitely recommend that you keep the Pentax, even if you get the Sekonic 508. I have the 508 and like many, purchased it thinking that it would solve...

There is an internet site for the cameras with specs under "camerachina.com/frame/frame-p-1-new.htm" It includes the 8x10 camera.

This doesn't answer Paul's original question, but I have had the same problems Richard has had with my BTZS focusing cloth in winter use. To solve the problem, I've used my old standard dark cloth...

Michael....I've had similar problems when I go on extended backpacking trips (7-10 days). All the 4x5 lenses go in a smaller daypack that ends up in a larger internal frame pack. I always ...

Bruce....I struggled for years with the flimsy mounts and the very expensive mounts. I finally found a mount I really like and the cost is reasonable. They are called Baer Mounts and are...

I have used the Toyo AII with both a 75mm and 90mm lens without ever having to drop the bed to avoid vignetting. About the only time I've felt a need to drop the bed is when using the longer LEE...

I have used a Gregory Wind River Pack for backpacking with a camera but never as an individual photo pack...my Lowe pack does that better, despite the higher co st. With my Gregory, I pack all the...

I too have been searching for a good 5x7 E-6 lab since I can't find a decent one in Salt Lake. I believe my search has ended with a lab called Edgar Praus Productions. They are out of Rochester,...

Here's my $.02. Buy yourself a used 5x7 (some old B&J's can be bought for less than $500),cut a 5x7 dark slide in half or buy a 5x7 panoramic board (Toho) from Badger Graphic, then use that cut...

As Bill and Glenn have mentioned, the Nikkor 300M is the longest lens I use on my Toyo AII. When I need to focus closer than 10-15ft with this lens, I just use an inverted recessed board which...

I'm using a 75mm with my Toyo AII with a recessed lensboard. I've never had problems with the flatbed vignetting. I also use a 90mm without a recessed board. Both have worked fine.

I agree with Bill....go with an 8x10 and use a 5x7 back when that format is need ed. You should have a greater choice of cameras in the 8x10 range. For me, the 5x7 format is a fabulous format. By...

Stewart: I have had similar problems with undeveloped white corners with Polaro id Type 52 film. I think Bill's suggestions are worth a try. But even with cle an rollers I still get the white...

I am interested in projecting some of my 4x5 transparencies onto a wall or scree n but I have yet to figure out a way of doing so. I've tried overhead projector s without success (too dark) and even...

I have an older Fujinon 75mm lens with very limited angle of coverage. Often in using the lens with extreme front tilt I get some vignetting. I understand why and to compensate I'll often lower the...

I would have a hard time buying a changing bag that is not guaranteed to be light tight. That the sole purpose of the bag. In the field while backpacking I carry my changing bag on my back...my...

I've always thought I've understood why wide angle lenses produce uneven field illumination....the light entering at an angle creates an aperature with an ellipse rather than a circle, causing...

With loupes and life, you get what you pay for. I started with the Peak 10x suction cup loupe thinking it would solve a continual problem all LF users have, focusing and holding a loupe on the...

The folding hood still makes a great protector for the ground glass. I do use the Darkroom Innovations focusing cloth (really nice and worth the price) and just tend to move the hood out of the...

My friend has the same Ries A250 head that Mike has. My friend swears its Gods gift to tripods....in other words he likes it. He also has an 8x10. The few times I've used it, I too have been...

I have a Toyo 45 AII and the extended length Toyo Loupe. In theory the idea sounds great, but in practice I find that the loupe barely extends beyond the length of the focusing hood causing the...

Keep in mind that all the LEE 4x6 filters already come in a nice filter pouch. I have not seen a need to replace those. If that will not meet your needs, you may want to look at some of the Grip...

I too use the LEE system and have found it more than adequate. I did have a problem when using my 90mm lens and the regular LEE holder. It would vignette in the corners. I tried the wide-angle...

The Adorama spot meter is essentially a Soligor meter. I have used the digital model for many years and found it to be more than adequate for what I needed. I t is not fancy and does not have all...

Lens caps are for protection...not filters. I agree with Ansel, only use a filt er to protect a lens when sand or dirt becomes a factor while photographing. Fi lters, IMHO, are to be used to...

I've had a Toyo 45AII for a couple of years and I have used it in temperatures as cold as -10F without any problems with the bellows. The cold creates more problems with the fogging of the ground...

I too have tried to wade through Merklinger's book and found it both interesting but rather tedious. I have applied a simple principle that I once read in an old Zone VI catalog regarding...

I agree with Ellis. If you wish to use a 58mm lens on the Tachihara I don't believe it will work. For one, you will need a bag bellows. For another, unless you have a moving rear standard your...

Howard: Excellent questions. IMHO the Toyo is a better camera because it is sturdier, it locks down tighter and the Graflock back gives you more options in choosing a 120 back, if that is...

I agree that the Horseman roll film back is less suspect when it comes to film flatness. It uses two rollers that work in tandem to "pull" the film flat as opposed to Calumets and Toyos system of...

Back when I had a Tachihara I did use one of the "fatter" Calumet C2N 6x7 holder s without any problems. Although the Tachihara seemed to be looser in the back, I just made sure everything was...
