I can see possibly doing this with an in camera bracket of three (or more) and then applying digital filters to the files and combining them, maybe.

In the old days, it was either 3 exposures on tripod via screw in filters and a...triple exposure.

...OR...

We also would make a homemade "drop through" filter out of Kodak test strip boxes. The box was thin and long...we would attach blank (for black out) then RGB filters in a row, You attached the box to the lens with the blank (blackout slide) in place, then open the shutter and let the RGB filters drop past the lens, for a quicker RGB sequence.

In digital days, just shoot 3 exposures in rapid sequence and make on R one G and one B then blend all three in Photoshop....some more examples, below:

Mine are 'not so bad'

That's a neat effect, Bruce. I have filters for B&W from the old days. I might try that thanks to your tutorial. Those filters, and several more, have been screwed together with caps on either end for decades. I wonder if they'll unscrew. Rich

Hello Rich...

You can also shoot through the RGB filters that are screwed together, to block visible light...

Increase exposure by about 10 stops....and it looks like digital infrared!

Re: walk the line

A beautiful pastoral scene and a portrait of a handsome young man both shot with the 'plastic fantastic' lens. One of the best bargains ever.

Re: * A nice Sunrise....

A nice sunrise indeed Roy. Haven't seen the sun here for a day or two. It's raining but the gardens need it badly. I could do fine without it.

Like the first Andrew. I see my mother in law is still flying around on her broomstick.

Re: Looking Back ....

A reminder of happier times WN. Hopefully things will get back to some normality for us all soon.

Take care and stay well.

Lilies

It's been raining for the last few days. It happens every year at this time when the schools break up for the holidays. I received a new to me lens yesterday and despite the rain went into the garden to take a quick test shot. The lens is a Tokina 28-70mm ATX pro which must be over 20 years old. Seems OK.

Re: Lilies

Thanks Bruce. Can't wait to try it out properly but the weather is not cooperating at the moment.

"Nature's Miners," on the XZ-2.

Root beer bottle migrated onto this treasure. These boulders originate in the lode quartz to the West of Taos and East of Tierra Amarilla, NM. Erosion separates them and human miners separate the veins, harvesting them, near Hopewell Lake, Tres Piedras, NM. In geological time, erosion brought them twenty +/- miles south, to the North Bank, of the Río Chama, where nature's miners bring them up. And, land speculators, harvested the particulates, along the Chama, just above my home, using placer techniques. I've documented the placer pits left behind around 1880.

Thank you very much, Member and Host 19andrew47. Love the Baby Moons on your "troquita." I borrowed the English word.

Re: Universal Studios: Harry Potter World pt2

The last is close to the original but still manipulated in post. I think I have only used an in camera ‘art filter’ once, ever!  Quite a bit of processing to get the first. All done in PSP and Nik Color Efex. I may use an image straight from the camera one time out of one thousand. Even that may be more often than actual Roy.

Looks good Dave. We used to have lilies like those but they did not survive.
