FujiFilm RAF/RAW Process Interactive Comparison | Terrance Lam

FujiFilm RAF/RAW Process Interactive Comparison | Terrance Lam | Fuji X-Pro1 | Scoop.it

 

Just a small follow up on all the RAW experimentation I've been doing with the FujiFilm X-Pro1 RAF files. Here's an interactive mouseover table to see the differences. Areas too look for are in the wood grain (you'll see a lot of colour or chroma noise in the different examples), Smearing of details (look at the texture of the walls to see how it gets smeared and creates the water colour effect), Aliasing issues (look on hard contrast edges to see a zipper aliasing effect), and lastly loss of details (in the red brick you'll see the various levels of details in the pores of the brick).

 

Some quick comments:

DCRAW 9.16: Gives the highest details, however has aliasing artifacts. Some chroma noise (even after filtering). Command line prompt only. Requires some technical know how. I use VNG interpolation and 15 pass median filtering.

 

1/2 Median: Is the filtering I apply to DCRAW to combat the aliasing artifacts. Requires a program that has Median filtering, and very process intensive.

 

Raw Photo Processor (RPP 4.7): Utilizes DCRAW and acts as front end. Works very well for details, but aliasing and chroma noise is high. My technique of 15 passes of median averaging in DCRAW clears up more chroma noise than what is produced by this program.

 

Graphic Converter (Patched): Patched with DCRAW 9.16 gives very similar results to RPP however this program is much friendlier to use than RPP and has some real nice post processing options. Could almost be used as an all in one solution.

 

In Camera JPG: The default standard. Still exhibits some detail smearing compared to something like DCRAW output, but has no aliasing or chroma noise artifacts.

 

SilkPix Developer Pro 5: The software that is part of Fuji's RAW processing uses an older SilkyPix engine. This current version is very clean however does show some chroma smearing (look at the green colour that appears under the window ledge and the loss of other colours). Shows very little chroma noise and no real aliasing errors. Very clean output and slightly softer than raw DCRAW output, but lot less aliasing even over the 1/2 Pixel Median filter. I would highly recommend this option if it weren't for the fact that the cost of the software is pretty high.

 

FujiFilm Raw File Converter: This software bundled with the camera uses an older SilkyPix engine. It does a pretty good job, but the interface is very difficult to use and understand. Compared to the latests version of SilkPix it exhibits chroma noise and some detail smearing.

 

Lightroom 4.3: Has low amounts of chroma noise, but very heavy detail smearing. Loss of details but no aliasing artifacts. Even at 100% it's hard to see the 'Watercolour' effect if you don't know what to look for. I suspect a very heavy pre-demosaic median filter and bicubic interpolation algorithm is the cause of the issues. However it's still one of the easiest to use, and if you can handle some of the image quality loss, most likely won't notice the detail loss.

Sensor Crop Factors and Equivalence | Nasim Mansurov

Sensor Crop Factors and Equivalence | Nasim Mansurov | Fuji X-Pro1 | Scoop.it

The subject of sensor crop factors and equivalence has become rather controversial between photographers, sparking heated debates on photography sites and forums. So much has been posted on this topic, that it almost feels redundant to write about it again. Sadly, with all the great and not-so-great information out there on equivalence, many photographers are only left more puzzled and confused. Thanks to so many different formats available today, including 1″/CX, Micro Four Thirds, APS-C, 35mm/Full Frame, Medium Format (in different sizes), photographers are comparing these systems by calculating their equivalent focal lengths, apertures, depth of field, camera to subject distances, hyperfocal distances and other technical jargon, to prove the inferiority or the superiority of one system over another. In this article, I want to bring up some of these points and express my subjective opinion on the matter. Recognizing that this topic is one of the never-ending debates with strong arguments from all sides, I do realize that some of our readers may disagree with my statements and arguments. So if you do disagree with what I say, please provide your opinion in a civilized manner in the comments section below. Before we get started, let’s first go over some of the history of sensor formats to get a better understanding of the past events and to be able to digest the material that will follow more easily......
