These comparisions are far more detailed than comparisions of MTF50 or other summary results. MTF Compare ( Imatest Master only) is a post-processor for Imatest SFR that compares the MTFs of different cameras, lenses, and imaging systems using saved data from CSV files. It can analyze regions as small as 10 x10 pixels. It also analyzes Chromatic Aberration and noise and calculates the Subjective Quality Factor (SQF)- a measurement of how sharp a print of a given size will appear, based on MTF and the eye's Contrast Sensitivity Function ( CSF). Sharpening algorithm allows you to compare digitalĬameras on a fair basis. SFR measures the sharpness of cameras and lenses using a simple slanted-edge target (either the industry-standard ISOġ2233 chart or a target you can print yourself on a high quality Imatest Master also analyzes Bayer RAW files. Image files can be in any of several standard formats (TIF, high quality JPEG, PNG, etc.). Imatest consists of several modules, each of which analyzes images of one or more test charts.

Their tight integration with Imatest Master makes it easy to get them up and running quickly.

It’s free so you have nothing to loose by giving it a try you might like it. Hugin (last application of my list) appears to be a perfect solution but for my taste it’s a little difficult to use. Both PTLens and LensFix use Panorama Tools to do the mathematical calculations. LensFix apparently uses the same lens library as PTLens. Tom has an extensive library of lenses that PTLens is calibrated for and if your lens is not in the PTLens database (not likely) you can calibrate PTLens for your lens. I’ve used PTLens by Tom Niemann on Windows for quite a while and seen it get better and better over the years.

Right now I’m leaning towards using LensFix for the Mac which is essentially a Mac version of PTLens. This list is probably not complete but I think it has all the most popular lens correction applications. I’ve been compiling the results of my search here. I decided to see what other options are available these days. Also, I don’t like the fact that I have to pay a premium for the version that works with my 1Ds and 16-35mm zoom and yet that version doesn’t work with files from my old CoolPix (or any other camera) which has worse barrel distortion than my 16-35mm. It seems to work all the time with JPGs but doesn’t want to display some RAW files… not sure why yet. Also, fixing barrel distortion and perspective was not as smooth as I’d hoped it would be. So, much of what you are paying for with DxO you already have with Lightroom. After a few days of use I began to realize that 80-90% of the functionality of DxO is an overlap with Lightroom.

So last week I downloaded the DxO trial and started checking it out. My first reaction was that I just need to bite the bullet and get a copy of DxO since the newest version apparently works with Lightroom. Using PS CS3 to correct verticals and barrel distortion is like cracking eggs with a sledge hammer. Photoshop CS3 is the obvious choice but is expensive. You’d like to find an application for your platform that is easy to use but doesn’t cost a bundle. If you are a Lightroom user you need an application to correct barrel distortion and fix converging verticals since Lightroom currently doesn’t do either.

Lightroom 1.3 Update Feature/Problem SummaryĪ discussion going on in the Flickr PhotographyForRealEstate discussion brought to my attention that other Lightroom users are going through the same evaluation of Barrel distortion and vertical fixing that I’m going through after my recent addition of a MacBook Pro to my tools.
