Re: S21 ultra: 108mp in RAW

Hello JoeD,
do you happen to know if gcam allows you to save the images from the 108mp camera in DNG?
If not, then I would save myself the extremely tedious installation of gcam.
Best,

Re: Is it some kind of microscope?

Hello Viktor j nilsson,
I still think that it would be perfectly fine to submit images taken with the rig above, though.
I think so too.
No particular brand of microscope is required.
Then it seems that this one made by ADi can be accepted :-)
Best, ADi

Re: Is it some kind of microscope?

Hello Ray_parkhurst,
Most "microscopes" have substage (transmitted) lighting for viewing slides
For this reason I use the the Köhler from Lomo:

Re: Is it some kind of microscope?

Hello Scarodactyl,
Sure, though if it doesn't have a viewing eyepiece it's a fancy digital microscope.
Yes, a magnifying glass is used as an eyepiece, namely this one:

Is it some kind of microscope?

Hello everybody, I would like to ask you whether this "thing" can pass as a microscope in the general sense: M_TPnd_WS1200_TPc_SC1024_Q87.jpg 1.) microscope - objective 2.) tube - lens 3.) eye - piece 4.) object - table 5.) cross - table 6.) condenser 7.) fine - drive 8.) filter - holder 9.) photo –...

Re: S21 ultra: 108mp in RAW

Hi Rik,
Nice comparison, many thanks!
I could imagine that the advantage could be greater if the chip were bigger.
But then the lens would also have to be bigger.
Perhaps as an attachment on a smartphone.

Re: S21 ultra: 108mp in RAW

Hi Rik,
Not bad, but I would say that there could be more potential in the RAW files.
there must be some difference between what Flickr will offer to Adi as owner of the album
yes, probably not a bug but a feature :-)

Re: B&W

Hi Lou,
It could be something like that:
Layer/Level -> New Setting/Adjustment Layer/Level -> Black&White

Re: B&W

Hello Lou,

I used two methods:

1.) control layer → black/white
(sometimes reduce saturation and increase the brightness before)

2.) channel calculations
red
green
soft light
new document
mode → grey filter

And finally tone correction.
