Old dual band photos (ZWB2 2 mm only)

[Stefano]

Today is one year of membership for me. I only uploaded a fraction of the photos I have, and there are some old photos (I already wrote 2 topics about them) which I never uploaded.

 

Back in September 2019, I tried to take UV+IR photos using only 2 mm thick ZWB2, no BG glass. I was really happy on how they came out, nice blue skies and white foliage.

 

Camera was my DMC-F3. I initially white balanced on a paper tissue, and this gave me greenish-yellow foliage and pale blue skies. White balancing on foliage instead produced the results shown below.

 

Some photos are a bit overexposed, but I like them the way they are. Also, I used ISO 1600 for all of them, but I wrote that anyway. I also hope I will be able to write "f/" instead of "F-stop" in the future, as I am not sure if that f-number was the lens only or if there was something else involved.

 

F-stop: f/2.8, ISO 1600, 1/1000 s exposure.

 

F-stop: f/6.2, ISO 1600, 1/250 s exposure.

 

F-stop: f/2.8, ISO 1600, 1/640 s exposure.

 

Polycarbonate blocks UV. This is to show UV was mapped as blue.

F-stop: f/7.1, ISO 1600, 1/160 s exposure.

 

F-stop: f/2.8, ISO 1600, 1/1000 s exposure.

 

F-stop: f/6.2, ISO 1600, 1/200 s exposure.

 

F-stop: f/2.8, ISO 1600, 1/500 s exposure.

 

F-stop: f/4.4, ISO 1600, 1/200 s exposure.

 

F-stop: f/2.8, ISO 1600, 1/320 s exposure.

Yes I like these. Similar to why I went with zwb3 for my IR HQ module. nice blue skys and whitish trees.

 

A whole year. Feels like yesterday. I think I joined in April of 2018 adtee lurking and reading most posts for a year.

They are pretty. Looks like mostly infrared.

Thanks. I will have to retry them with my new camera. Not now, as there are no leaves, but next spring.

 

David, according to your profile you joined April 19^th 2018.

Stefano, Looks good. How are they white balanced? White balance looks good, just asking, but any other processing? Do you have Photoshop? If so, try auto levels, I tried with your 5th photo (Church),

a nice improvement using auto levels. Some other Adobe programs probably have auto levels also, and when auto levels makes the color look worse, then try auto contrast alone.

Just saying.

The white balance was set in-camera on leaves. I don't have any program except IrfanView, which can help sometimes. I usually don't post-process my images a lot, if any, but I do sometimes play with saturation, contrast and so on to see what comes out.
