As with the Samsung profile you created, a great example of the strength of a community.

Sony a7 II Raw Tone Curve

Happy new year,

Can anyone help?  

Has anyone created a raw tone curve for Sony a7 II or do I have to follow Doug's instructions?  I have just bought a secondhand one - love it!

I have tried t-legiaw's a7s file but it does not seem to work - maybe I not using it properly but i saved it in the templates folder and just updated to 4.1.7.

Any pointers would be very helpful please....

thanks

Sony a7 II Raw Tone Curve

Hello Calum,

a profile for the Sony A7 II is already contained as a bundled resource in LightZone (v1.7.0). This profile is applied automatically when an Image for this camera is loaded.

note: to make this profile explicitly visible under CameraDefaults you can also extract and install this profile by yourself:

<code>

cd /tmp

jar -xvf /usr/share/java/lightzone/lightcrafts.jar

cd com/lightcrafts/ui/editor/assoc/resources

cp -p 'SONY ILCE-7M2.lzt'   "$HOME/.local/share/LightZone/Templates/CameraDefault;SONY ILCE-7M2.lzt"

</code>

Hi Hans

Many thanks - I found the profile in the lightcrafts.jar and extracted it to my templates (and added "CameraDefault;").

However when I go into edit mode I am still getting an unusual red mess - i am not sure why I can view thumbnails but not the raw image in edit? (I also have a SLT-a57 with that profile loaded with no problems).

Any advice would be very welcome!!

What is wrong with the bundled

profile? With this sample - if this is the right camera - everything works out of the box.

I suggest you to remove the CameraDefault profile(s) for this camera from templates (temporarily at least) and simply use the one, included in LightZone.

Or, what is quite possible, I don't understand your problem correctly.

Sample Image

Hi Jacal

Thanks for the link to the sample.

I downloaded it and navigated to it in Lightzone - it worked perfectly!! Even with the CameraDefault profile!

I am well out of my depth understanding this but one other aspect I had not thought about before is that I set my new a7ii to shoot RAW "uncompressed".

Does anybody know whether that might be the problem?

Many thanks!!

Jacal
A sample photo

would be helpful, something you can't open in LightZone. Upload it to filebin, dropbox or some similar service, please.

Sample Photo

Hi Mart

After a long while away from home I have finally managed to upload a sample shot:

https://filebin.net/606ugncc4axwl48l

The uncompressed RAW is twice the size!  48Mb vs 24Mp sensor. 

This was introduced with one of the last firmware updates so I hope this helps to understand what Sony have done - I can't be the only one to experience this.

Thank you

Red mess

Hi, Calum!

Currently I happen to be away from home, with a limited Internet access, but I can confirm, that LightZone (Win, Linux) can't render your photo.

The half smaller sample A7M2FAR2I0100.ARW is in compressed raw format, and yours says it is a 14-bit uncompressed raw (shot with newer firmware). I can open it in RawTherapee 5.0-r1, the latest PhotoFlow and even with the rather outdated Partha's darktable 2.0 for Windows.

The current version of LightZone is almost half a year old, it is possible that you will have to wait for the next version (with updated dcraw) to support this format. (On the other hand, if I remember correctly, gentlemen from DPReview were not happy with Sony's raw compression, so you might want to stick with uncompressed format. A very clumsy workaround is conversion to DNG, I would rather use other raw editors for the time being.)

I hope this helps a little, be well,

Mart

Thanks

Thank you Mart,

I was a bit surprised to see the red mess first time I opened it but at least it comfirms that I haven't done anything wrong.

I have read mixed reviews on the compression but I think I will turn it back on.  Firstly, 48Mb file size for each photo from 24Mp sensor is way too much for me and I want to use Lightzone again for non-destructive RAW editing - I bought Affinity Photo which seems to be great for the Photoshop type tasks but not a patch on Lightzone for tonal adjustments.

Many thanks

Calum
