Greetings,
I am new to raw image development and trying to figure out what I am
doing wrong.
My main problem seem to be stemming out from the fact that when I export
the image, it does not look like image in darkroom screen. I am trying
to process images generated by Canon PowerShot SX60 HS. Exported image
always felt more noisy or grainy.
A little bit of experimentation and tinkering of many knobs, I figured
that exported image quality seems to be function of size. If I leave
exported size to 0, darktable exports in default size (in my case, it's
4768 X 3516), exported images look grainy. If I export in smaller size -
say 1600, they look much nicer.
Is this normal - having noise in default sized exported image and
looking cleaner in smaller image? Is there anything I can do to address
this issue?
Alternatively, what would be good or usual size to export the image? I
am just a home user of camera and darktable, rarely print my images and
images are used only for viewing by family and sharing across various
mediums such as facebook and WhatsApp.
I on Ubuntu 16.04, using darktable version 2.0.3 from standard ubuntu
repositories. I am using standard Ubuntu image viewer to view exported
image.
Best,
Niranjan
