Tool to remove DNG/RAW software lens correction instructions

Recommended Posts

Advertisement (gone after registration)

If you are using Lightroom as your favorite DNG editor, you are currently not able to "stop" Lightroom from automatically applying the DNG software lens correction instructions of the T lenses (DNG opcodes). Some applications like RAWTherapee do ask you if you wish to apply those instructions.

 

I have developed a small application (utility) to remove the DNG software lens correction instructions opcodes from the Leica T DNG files.

 

The software is still in a very early state, but it generally works and does what it needs to do.

 

You can download the first "alpha" version of the app OPCODE Remover here for free:

http://www.bitstorm.de/OPCODE_Remover.zip

 

Please note / be aware of:

  • The app is currently only available for Mac OS 10.6 or later and only runs on 64-bit Intel Mac's
  • I might develop a Windows version of the utility by popular demand
  • To be on the secure side: Always backup your DNG files before using this tool!!
  • The opcodes are removed permanently from the DNG files and are currently not restorable (that might be possible in a later version)!

 

Please only use the tool if you are accepting those terms:

OPCODE Remover is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY;

without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE or LIABILITY FOR ANY DAMAGES CAUSED BY THE USAGE OF THIS SOFTWARE.

If you do not accept those terms, DO NOT USE THIS TOOL.

 

 

Your feedback and suggestions for improvement are of course more than welcome

Also as a side note:

 

By offering this tool I do not express that the software lens corrections of the T lenses, embedded in the raw (DNG) files are a good or a bad thing.

 

It is just a tool which removes those instructions which might be helpful for someone which wants to keep the distortions or correct them "manually".

 

Again: This is not a judgement on the existence of these corrections...
