opuntia ficus indica - opuntia schumannii

I think we are getting far off topic again.

 

Toni the best digital colloidal simulation I have seen, is only when you strip out the blue channel response out from the camera and use that as a monochrome image.

 

You can use the command line software 4channels from the libraw installation to do that.

Deleted - not relevant. Getting my ZB and ZWB filters mixed up.

4channels softwareIt is free ? for Mac?

very interesting, but not as immediate as the BW on the monitor, the parameters are very difficult to compare.

ISO - 100 ... Vs 1 (variable from 0.5 to 2 ISO)

Lens - 50mm f: 2 (24x36mm) used at f: 16 ... Vs 275 f: 4.5 (180x240mm) used at f: 4.5

 

Therefore it is just an imaginative emulation that doesn't help me in finding the right exposure,

but it helps me to verify the composition unfortunately with a different DOF

White balance can be whatever you want, but I usually start with selecting the full frame in Photo Ninja.

If I don't like how that looks, then I might try some area that I think is neutral, or that I want to be neutral.

I think overall the question of this topic is white balance. Many year back my first white balance was done using ACR, but I would never use that now.

After two years I photographed a red opuntia.
A7 + Meritar 50 @f8~11
QB39 and TSN+ZWB2

 

 

 

I have reviewed the previous photos
instead of Photoshop I used Capture One
in this way the white balance is excellent
I was able to correct even the overexposure.

 

Unfortunately I broke that BG39 Jena Glass filter it blocked IR well :-(((
