I assume a little bit of IR leak in the UV photos is responsible for the skin tone, but not sure.

A bit of an odd sky tint in frames 4 and 5, otherwise good work. I like the last one as well.

Very nice work, Steve! Which camera was this shot with?

Also, out of curiosity, what size focusing helicoid are you using with the EL Nikkor? I'm looking at a few right now, and they vary from 12-19mm, 17-31mm, even 35-90mm. I'm guessing your helicoid is the smallest size for portrait work... 12-19?

Thanks, yea the WB was a little weird. There was no way to balance it "naturally". With the PTFE the sky just came out green, strangely enough. I'll see how a BG39 works with a UG11 under similar circumstances.

Got a metal EL 50/2.8 on the way that I'm hoping to pair with 12-17mm (won't reach infinity that way but hopefully will work with portraits)
Also have a beat-up metal EL 105/5.6 on the way that I'll try to pair with 17-31mm if I can fix it up first.

I modified a wider helicoid for my El-Nikkor 80/5.6 to both reach infinity and get more magnification with the same unit.
It works quite well.
See here about it: http://www.ultraviol...__fromsearch__1

My camera is a Canon EOS 60D.
(The same back flange distance)

The same modification, but for a Nikon DSLR must place the lens 2.5mm further into the helicoid, due to the different back flange distance.
This makes it more difficult to operate the aperture ring.

Steve, how thick is your BG40?

A S8612 2mm would be a more efficient alternative to surpress IR.

Wow, that must have been an expensive conversion! Did you do the conversion yourself?

I just bought an EL-Nikkor 75mm f/4 today off of eBay: https://www.ebay.ca/itm/372314039957, plus 2x M42 mount helicoids from AliExpress.com, plus a 34mm to 52mm filter step up from rafcamera.com yesterday. No doubt the helicoids will arrive last (I expect a month or more from China - most of the delay is Canadian Customs).

Can't wait to try it out!

My Nikon D3200 is impossible to custom WB in UV and with most of my IR filters in place.

You have some really nice pink and olive tones in the first photo. The best I can hope for is a monochrome photo with a purplish cast in most cases (only dandelions come through with their yellow petals - nearly all other flowers render as blue). I guess that's the difference between UG1 and UG11 glass.

Ah very good
Any experience with mounting the EL 50/2.8?

Not sure about the BG40, but I'm now using a BG39 that is 2mm. I've found the S8612s to be a little expensive. Perhaps if manage to find a cheaper copy ...

Not too expensive since it's a 10-year old camera, but had it converted for me. Tried the conversions before, but thought better than to do it myself for a FF.

Make sure the 34mm is going to be ok - for my EL 80/5.6 I needed a precisely 34.5mm adapter. They're more difficult to find, but there are some sellers that custom-machine it for the EL Nikkors

Custom machining is going to be too expensive. I have 2 possible solutions:
* I'll try using some plumber's tape first. It's usually made of PTFE, so the bonus is that I might be able to stick some strips of it to a piece of card and try setting a white balance against it (unlikely, given how fussy the D3200 is, but it's worth a try).
* If the plumber's tape doesn't work, I'll just epoxy it in (which will mean I can't use it with any other EL lenses I may buy, so that will be a last resort). The overall cost to buy another one from rafcamera.com isn't too bad, if I acquire another EL lens. The 75mm f/4 and helicoids will satisfy my gear acquisition syndrome for a while :)

Found this one at not too extreme a price:

https://www.rafcamer...-52mm-to-34-5mm

Not exactly at the 99 cent price point I usually find for Chinese adapter rings, but not too much gouging

Thanks. Looks like I didn't search hard enough on that site. It's the same price as the 34mm I purchased there, and my 34mm is already on its way, so I'll save your link for future ref.

No, not really.
I think it will fit inside a 52mm helicoid but that it will be difficult to reach infinity then, just as it is with the Focotar 50/4.5

No worries
If you ever need standard-size step up/down rings in the future (I've found that UV photography demands a lot of them), you can normally find them for $1-2 on eBay

The first two IR photos are wonderful!

I was wondering why some of these are not cropped for a bit more dramatic effect? You have some nice compositional elements in many of the scenes with the diagonals and the "stripes" but in some shots there is too much distraction. Of course, you might have been just presenting the initial series and cropping refinements would come later. In which case, kindly ignore my question. :)

Very minor edits so far - just quickly selected a few that might be interesting. I'll be posting proper edits in a few months once some time frees up!

I agree with Andrea about the improvement potential.

When looking at them in the beginning I saw interesting very nice images and then looked for the UV- and IR-related details.
After Andreas comment I looked again, downloaded and played a bit with one of your images. I think it became even better.

Steve, may I show how I cropped your image here on the forum?
