Hello everyone.

Haven’t posted anything related to PerfectRaw for a long time. Well, apparently the team working on it is leaving it behind, moving forward by launching new websites, Manuel Llorens site, and working on other projects.

I’m moved by this decision guys made, but on the other hand I can understand their situation. Without financial support and having families is pretty hard to work on a project just “for fun”. But, we are all very thankful to them…well, at least I am. I’m still using PR 0.65 and I love it.

And there’s also a hope. Manuel made the PerfectRaw 0.65 code public, so that anyone interested in the continuation of the project can participate.

I’ll keep following the PR project and if there are some major changes in it’s way to nr. 1 RAW developer… I’ll post it here. Until then I think I’ll fill this blog with my photography and share it with you.

Actually I don’t know why haven’t done this so far..

You can start by checking out my photojournalist skills by visiting my profile at Demotix.

Have a great light…

As time moves faster (at least for me) and the necessities grow bigger and waiting for PerfectRAW version 1.0 becomes unbearable (at least for me), there some updates available.

I check the Ojodigital forum everyday, even twice a day, and always find useful information.

Today I found some information about the interface of PerfectRAW:

-Check it out!->

It’s been a while since my last post. I’ve been busy with finding a job (still looking) and had a small trip to Serbia.

What I do every day is checking how perfectRAW is developing. There are no major improvements so far, at least for me as a advanced user of PerfectRAW. For people who are getting used to it I would tell that the team is working on a great new interpolation algorithm named Amazed and Egon, who’s working on the interface has done some great job bringing PerfectRAW on a new level.

perfectRAW 0.70 Alpha is ready to be downloaded in tested.

Here’s a small update to the upgoing PerfectRAW project.

I copied it from PerfectRAW Forum

Very soon a new version of PerfectRAW will be available with a more easy to use interface. But, until then I’m about to show you my workflow with PefectRAW 0.65.

I chose an image with contrast problems and a lot of branches. In the field I chose a high aperture number (small aperture ring) to eliminate chromatic aberrations.

This is the original RAW file.

Feel free to download it and try it yourself with your RAW converter and compare the results. I tried it with RawTherapee and ACR and it didn’t work for me. I’m not going to post the examples because I’m not a professional at these softwares, but if someone gets a better results using ACR or other software please feel free to send me some links with your comparison.

-The Workflow->

Hello everyone!

I noticed that most of the visits to my blog are related to PerfectRAW, that’s why I decided to write more about this great open source software.

First of all, I want to announce that an update version of PerfectRAW is available.

-PerfectRAW v. 0.65->

I’ve been following the PerfectRAW almost since the beginning and I must say they are very serious about it. A lot of time they spend working on noise reducton features that the software would provide. Combining interpolation algorythms with different techniques of denoising is what will make PerfectRAW a really good solution to problems that high ISO images encounter – noise. The AFD method of interpolaton already provides a really good possibility of solving the noise problem without affecting the texture. But combined further with other applications it may result in a noise free image and good preservness of texture.

Here’s how:

I always try to get the most from my photos which means as much info as I can. This would consider shooting RAW and using it’s features. For this, one needs a very good RAW Converter – the software that reads the real, true and full image information from the RAW file.

During my attempts of using different commercial software and reading tons of tutorials, I realised that actually it is not me who deals with those genuine pixels from my RAW file but the software I was using.

One day (can’t remember how, honestly ) I came across DCRAW, a small open source .exe file that can be used with the command line for decoding RAW files.

This is what Guillermo Luijk has to say about DCRAW: “My personal opinion is that I love DCRAW as a RAW development tool not only for experimenting but in a regular workflow. The key is to do in Photoshop all those extra features that other RAW developers can do apart from pure development, and consider DCRAW as a tool that provides a rough image without any kind of processing applied on it, just a high quality development under absolute control. “
