Panasonic S1R Filter Series (14 filters as of 15 June 2022)

[Andrea B.]

I thought I would run a filter series with the full spectrum S1R using several filters I have. I would show both the raw colors and the white balanced version.

 

For a similar series, here is one I did with the Pentax K5 full spectrum conversion: LINK

That is some task....

A rare couple of days with overcast skies has stopped me from getting started with my little filter project. It would be really nice if there was some rain to help put out the forest fires in the NE of my state, but so far - none,

Scene

The scene includes blue sky, juniper shrubs, aspen trees and dried grasses. There are some rocks in the foreground. What looks like clouds in the sky behind the mountains is actually billlowing smoke from a large forest fire in Northern New Mexico which is now into its second month. It was breezy with some gusts, so you might spot some motion blur in the grasses or leaves.

 

Side Note

These examples, featuring 14 different filters and 1 visible reference, were made hand held. The S1R has stabilization in the body. It also has a feature named Sheer Overlay which helps you to align a current live view scene with any preceding photo of your choice. And that is why I have the boringly composed white tree trunk in the middle of the frame. It was an easy alignment target.

 

Minimal Processing

White balance was set in-camera for each filter by measuring "against the scene" where the smoke, some sky and some tree leaves were included.

 

Each file was converted in Luminar and white balance was checked against the white aspen tree trunk and against the smoke. The small detail slider was used at a low setting to give some micro-contrast enhancement. A dust bunny was eraased. No other edits were made in Luminar. The proofs were then resized and converted to JPGs in Photo Mechanic. A small amount of sharpening was applied to the resized image.

 

The raw composite files were made in Raw Digger to show how the S1R records the colors before white balance is applied. Because a raw composite can be rather flat, the white & black points were adjusted in Photo Ninja to provide a bit more contrast and brightness. The detail slider was used at 10-15 to give some micro-contrast enhancement. No other edits were made in Photo Ninja to the raw composites. The proofs were then resized and converted to JPGs in Photo Mechanic. A small amount of sharpening was applied to the resized image.

Schott RG715 x 2.0 mm

The RG715 result is very much like the next B+W 092 IR and Hoya R72 results.

 

 

 

B+W 092 IR

The 092 IR rendering is very similar to the preceding RG715 and the next Hoya R72 scenes.

 

 

Hoya R72 x 2.0 mm

The Hoya R72 scene looks like the preceding RG715 and B+W 092 IR scenes.

 

 

B+W 093 IR

There is still a hint of false color in the raw composite, but by 830 nm the tint disappears after white balancing.

Hoya B-410 x 3.0 mm (dual bandpass)

A very colorful final result given the somewhat dull raw composite.

 

 

 

Schott BG3 x 2.0 mm (dual bandpass)

Both the finished image and its raw composite have strong colors.

 

 

 

Schott VG9 x 2.0 mm (green bandpass)

Typically we wouldn't white balance a primary color filter, but I wanted to see what would happen.

 

 

 

Hrommagicus

This is an Aerochrome style stack the elements of which I don't recall right now.

The first version shows the natural white balance. I very slightly increased its red saturation.

In the second version, I pushed the red-orange towards a deep cherry pink.

 

 

 

B+W 099

This is an old longpass filter which is no longer made. 

The raw composite appears to have olive yellow, peach and lavender colors, but they are actually yellow-orange and yellow-orange when measured. So there are some eye & brain tricks going on when you look at those raw colors.

 

 

[colinbm]

All good Andrea, but I am particularly drawn by the 'deep cherry pink'.

[Andrea B.]

Me too!

I would probably whiten the clouds a bit more in that photo (and maybe a few others)

if this were not a topic for demonstration of raw color and white balanced filter colors with the S1R.
