Rawtherapee

Have been doing a bit more experimentation with rawtherapee – it’s possible to build custom profiles and up till now I’ve mainly just used bundled profiles.

For example it’s possible to create a “unprocessed” profile and then use that as a starting point rather than starting with a bundled profile and then tweaking that, and I think I prefer this.

I have set up a “size” profile to resize within 1280 x 1024 dimensions and then I can simply “add” this profile to an existing processed image.

For this image the only adjustments were:

  • exposure compensation +0.43
  • contrast +17
  • resize to 1280 x 1024 boundaries

 

Ricoh GR sensor dust

Looks like I have an annoying dust bunny and the lens cannot be removed so no chance of easily doing it myself like with a DSLR!

I’m hoping this will get fixed under warranty.

f/16 – very annoying!

R0004329

f/11 – still v bad

R0004330

f/8 – not good

R0004331

f/5.6 – blurry now

R0004332

f/4 – quite blurred

R0004333

f/2.8 – very blurred but still visible

R0004334

update 9/1/14:  just noticed that the “dust bunny” has shifted a bit!   I’m hoping this is a sign that it’s not “welded” to the sensor and might drop off.

I normally keep my GR in the pannier on my bicycle, so I’m hoping that the constant vibration might eventually shift the dust altogether.

I have put the camera loose in one of the pannier pockets so more vibration is transferred to the camera and with the front face (lens side) down as well.

Installing Nvidia Driver in Ubuntu 13.10

This was a bit fiddly as first of all I was getting messages that I was running an x-server, so I found that by hitting:

CTRL + ALT + F2

that it would exit to a command prompt.

I was still getting a message about running an x-server

R0004231

so I then typed:

sudo service lightdm stop

and then did the install using the following:

cd Downloads

(as this is where my downloaded file from nvidia was located)

chmod 755 NVIDIA-Linux-x86_64-331.20.run

(this command makes the NVIDIA-Linux-x86_64-331.20.run file executable)

sudo ./NVIDIA-Linux-x86_64-331.20.run

this actually “runs” the “NVIDIA-Linux-x86_64-331.20.run” file that I downloaded from nvidia

this actually seemed to work and did run the file in the non graphical interface.

These are the screenshots from the install

First an error message saying:

ERROR: Installation has failed.  Please see the file ‘/var/log/nvidia-installer.log’ for details.  You may find suggestions on fixing installation problems in the README available on the Linux driver download page at http://www.nvidia.com.

Strangely this worrying screen did not cause any problems as it just went on to the next screen:

R0004234

the another rather worrying screen:

R0004236

but just click “yes” to continue

Then a nicer screen saying “Building NVIDIA kernel module:”

R0004237

then “building unified memory kernel module”

R0004238

then a screen asking if you wish to insall nvidia’s 32-bit compatibility libraries?

R0004239

Not sure if you need them on a 64 bit system and it seemed to work with or without them

the another screen

R0004242

then

R0004241

then

R0004242

finally success – it’s installed!!

R0004243

After a reboot

sudo shutdown -r 0

the nvidia driver was up and running and running

nvidia-settings

launched the nvidia control panel
