Amaryllis in the 500s with B+W 099 and Schott OG550 (and others)

[Andrea B.]

There was some discussion in another thread about the B+W 099 IR+Red+Orange filter and what Schott filter it was most like (along with other filter comparisons).

 

So, while I was photographing one of our Christmas Amaryllis plants which had just bloomed, I made some photos with my B+W 099, Schott OG 530, 550 and 570 filters. The B+W 099 and Schott OG 550 have the same color. I think my B+W 099 is coated, but I'm not sure. All my Schott OG filters are 2 mm thick and uncoated.

I've added a Hoya R72 photo also.

 

Here are the raw composites as produced by Raw Digger. After exiting Raw Digger, I adjusted the white & black points for each raw composite and added some detail sharpening. No color profiles were applied. (Of course stuffing the file into JPG/sRGB format for posting here may slightly have altered the raw colors.)

 

Raw Digger conversions are good enough, but I think you get a better demosaic/gamma/curve set from Photo Ninja. I always think the raw composites I present here in UVP are just a little bit "unfinished" looking. But we are using raw comps to look at raw colours, so I suppose it doesn't matter.

I consider B+W 099 and OG 550 to be "orange" IR filters.

These two photos are identical. The difference in exposure times is negligible. I made exposures of both at 1/13" and 1/15" and simply chose the most well focused one to use here.

 

 

 

I think the OG 530 is a "yellow-orange" filter.

 

 

And the OG 570 is a "red-orange" filter.

 

 

I'm adding the Hoya R72 just because I just got it and wanted to try it.

This filter passes a small amount of high red, but is primarily IR.

And the resulting photo was much softer than the preceding photos

although that may not be completely obvious after downsizing.

 

 

Here is the Visible Amaryllis for reference. The bloom is huge!

Looks kind of peppermint-y, doesn't it?

Great looking flower.

I wonder what your R72 image would look like if you used your Convoy flashlight as the only light source. For UVIIRF.

 

Also based on the OG530 image I think it would look nice using just a S8612 2mm on the camera lens and a 365nm light source for illumination.
