E620 post processing

[banksiaman]

I am about to purchase an Olympus E620 with Zuiko 9-18mm lens. I would like to print and display some landscape photos (about A3 size) but I’m concerned about chromatic aberration. Not really into post processing but feel it may a requirement with digital SLR photography. I have Adobe Photoshop Elements for managing photos and making small adjustments where necessary. Is Lightroom a better option? Can I shoot JPEG and use Lightroom to remove chromatic aberration, vignetting etc. or do I have to shoot RAW? Photo sales people are no help. This is a great forum! Intelligent, knowledgeable people who share the same passion. Thanks guys!

I have the same combo, but never found the need to correct CA, except if i needed to look a high contrast image at 100%, which I don't.

If you are a perfectionist there are two methods in PE: one is to do Color Correction, and pinpoint exactly on the slider the colour on the edges you want to eliminate.

The other one is even simpler: some plugins for distortion control also eliminate CA by default.

I am sure there are other methods, however for me the 9-18 works fine as it is.

Personally I prefer PSE v.3.01 to LR, lol. LR users seem to split into two camps, those who love it and those who hate it ... I far prefer PS 1/2/3/4 and Bridge.

Which version of PSE do you have? I understand that the latest version (8) covers pretty much everything many people will ever want to do.

I have version 6 and a review of V8 suggests that it has no significant benefits over 6. I assume you can eliminate CA in JPEGS or is this only possible when shooting RAW?

 

[amalric]

Also in Jpeg.

BTW the plugin I use is Debarreliser by TheIMagingFactory. It has a control slider both for the blue and red channels.

G'day again BM

The ACR RAW developer plug-in for the E-620 etc will work directly with v8. This is not the case with v6. To use v6 for E-620 RAWs you need to convert them to DNG files first. BTW, I always do this anyway, so no big deal.

I assume you can eliminate CA in JPEGS or is this only possible when shooting RAW?

I cannot say. I never edit JPEGs, only RAWs. For me, JPEGs are only for quick and dirty upload to the web, email etc. I always edit RAWs, saving them in a ProPhotoRGB 16-bit colour space, and then save to either a PSD-16 or TIFF-16 file. These are what I print from.

What is the advantage ( if any ) of using ProPhotoRGB in stead of Adobe RGB. I always save my converted files in Adobe RGB. Am I missing something?

Are you sure about that John? I recently installed the latest ACR in Elements 6, which should work with the 620. I though 5 was the cutoff.

Perhaps you should take some photos with your new setup before you decide you need to make a correction.

As Henry Ford said "Ask the man who drives one", lol. No, I'm not sure. I was assuming that Adobe plays the same game with PSE that it plays with PS - ' Want the latest RAW converter plug-in; buy the latest version of PS ' ...

So, does the latest RAW plugging work directly with PSE 6 and above?

I can use DNGs created with DNG 5.x with PSE 3.01.

Yes it does, at least PE6 for Mac, with ACR 5.4.

Converting to DNG is a private whim.

Sorry, mate. I missed your post until just now. I generally peruse the overnight postings in threaded view as well as my normal flat view to check for just such posts as yours; but I still missed yours! Ah well, I have never claimed to be perfect, although some others have claimed this for me on my behalf ... ROTFLMHO ...

It really depends on your understanding of colour gamuts ... sRGB used on the web is very short in the green axis; AdobeRGB1998 is far better, being both a wider gamut and not deficient in the green part of the spectrum. ProPhotoRGB is a wider gamut again than AdobeRGB (wider than the human eye can see, IIRC).

The greater gamut size allows for greater latitude in editing without significant colour shifts, and far greater possibility that the editing software, colour management profile and printer driver will be able to reach an amicable agreement as to what the "true" colour will be translated into when printing. IF I am correct here, this is about the limits of my understanding of this subject. Certainly the limit that I can explain!! If you want more, buy the book below ... and study it for a long time, as I have.

Here is a diagram scanned from Blatner & Fraser's "Real World Photoshop CS". This is a very technical but practical book. It devotes a goodly part of its bulk to explaining colour and colour management in all parts of digital imaging and editing. I recommend this book (or later editions) to anyone seriously interested in this core matter. Since I am copying a tiny part of this text (less than half a page) for the genuine purposes of education, I have not sought permission of the publishers, as I understand that this is within the copyright law. If anyone informs me differently, I will immediately remove this image.



There is a larger size available on my web site if you wish to download and print it for personal study here:

I hope this helps, rather than further confuses you, although I suspect the latter will probably be the case ...
