Good information. Indeed there is sodium chloride listed in the Formulary's intensifier MSDS too. I look around the Darkroom Cookbook book but did not find a intensifier formula listed using this...

thanks for all the good advice.
Safety is always number 1 when handling chemicals even more when dealing with dichromate and hydrochloric acid.

freestyle is selling a powder kit too here...

Trying out intensification myself in this video

Intensification is the process to increase contrast or density of a film or print through the use of chemicals. In this video I explored how can I...

i just relogin to https://collodion.com/ forum site too. 6 years ago there isn't much commercial wetplate related products and that site gave me a lot of ideas for DIY projects including ULF cameras...

These 2 were taken in Apr 2020. I will do another self portrait soon. maybe in RA-4 reversal.

Continuing my "lo-fi" DIY projects . "lo-fi" as in no advanced woodworking skills involved.

I picked up this Ikea wooden shelf and decided to upcycle it into a Afghan Box Camera.

Sharing a simple flap shutter built for this ULF lens - a 36" f6.3 aerial lens.
My requirement is that it need to be able to allow to open or close it from a distance when shooting my self...

Thank you. Been around here for a whule but only get to do youtube videos to share my experiments on film photography. Good to hear abt the darkbox build. The suitcase design definitely save more ...

i was gifted a 36inches f6.3 aerial lens by a friend. It was a huge lens weighing 8kg. The story was that a few years ago, my friend came across a store and saw the owner collected a few vintage...

yes, the damaged filter ring is on my good lens. The lens that has the fuzzy issue is not damaged in anyway that I can see and can be opened up. Also this lens is bought used from a Ebay Japan...

thank you all.
I opened the front element and there is a shim. my other lens has a bent filter thread so I could not open to do a comparison.
Otherwise I made sure all the lens elements are...

hi guys

I have 2 of these Fujinion W f5.6 210mm. The first one I have been using it for a few years and it focused sharp at infinity at f5.6 on the camera ground glass.
However for the 2nd lens...

thank you all for the comments, I will check out for first surface mirror as suggested.

Lovely demo. I never try hydrogen peroxide bleach before but might give it a go. Nice 8x10 developing tray used at 06:25. is that a DIY tank?

In making reversal shots (positive image)from my Afghan Box Camera, the photo will be a mirror image. So I built a mirror scope to fit onto my lens so that I can make the photo to be of the right...

Thank you. Good thing is fuji RA 4 papers is relatively cheaper than B&W papers. 100 sheets of 8x10 for abt $50usd on B&H

That is what i am planning to do do..both for 4x5 and 8x10

This is about as near as to color instant photography. Just abt 5 mins to get a color print 'out of the box'.

After a few sessions of exploring with friends aka RA4 Reversal gang, I learnt a few...

Thank you for shipping out the holder. Received my double 4x5 holders in Singapore. Dark slide feel good on one slide but tighter on the other. Should loosen up in time. Seems to hv an hairline crack...

Yeah.. went though these 2 and other RA4 reversal video youtube. Certainly helpful else I will not even know where to start.

Yeah maybe something close enough will do. The cyan cast remains so maybe we need to add a yellow filter of some kind.

Sent from my Redmi Note 5A Prime using Tapatalk

I see. Going to try some Arista magenta n yellow filters. Not sure will I do this long term but it was fun to do.

Sharing the RA4 reversal printing video here. What is RA-4 Reversal. Usually one use a color negative to print on RA4 paper to produce a color print.

In the reversal process, we use the RA4 paper...

Yup.. X-ray film seems to exhibit this easily ..maybe due to the fact that it is coated on both sides.

If you do wetplate photographgy, you might have heard of the saying "a positive is just an underexposed negative." Or " a good negative is a bad positive."

Will this work on film? What happens...

i cannot really comment on the tonality vs Fp4 as it has been quite a while since I shot FP4. The reciprocity failure of Shanghai is quite bad. You need to compensate for anytime 1 second or longer....

thank you. continuing my reversal attempts on film, paper and today I just tried reversal on RA4 paper but that would b for another video/post.

Nicely done. Usually I rate it as ISO100 and process in HC100 Dil B 20 C with continuous agitation. I just bought a box of 8x10 too. Happy to have it on 8x10 and bigger size.

My video was...

Here is a summary
1. came with a 2 part box instead of the 3 parts box. In the box, the sheets are first keep in a black plastic envelope and then a paper brown envelope.
2. The sheets are...

I have been using Shanghai film for a while mainly in 4x5 format. A few years ago, I was told that they would stop manufacturing film and I was quite upset but then they are back again after a...

I am sure you will. Let us know of you have build one.

Thank yoi Randy and Kent. Yeah if I can make it, so can anyone.

Not sure to post in the wetplate or DIY section but I guess it fit here better.

I made this darkbox for wetplate photography a few years back so it is only recently that I thought I do a video...

Thank you. Sound good. I am also working on a similar camera concept and i found a big front surface mirror would cost more even i can find one.

Sent from my Redmi Note 5A Prime using Tapatalk

very nice. do you use a normal mirror or do you need a front surface mirror ?

Very well made camera. Thanks for sharing.

Thanks for sharing the experience. Do show us some photos of the camera and holders when you have the chance.
