Dependence of image quality on different RAW format (or camera)
Does quality of processed image completely depend on the RAW converter used? or it also depends on the camera RAW format (or camera). Suppose if I use Nikon, Canon or Pentax camera and shoot .NEF, .CRW or .PEF respectively, and process all using ACR, should I expect the same image quality from all of them?.

If you were using COMPARABLE QUALITY LENSES for each camera and then tweeked each RAW conversion to bring out the best for each camera's image (not just relied on the ACR defaults settings) then my assumption is they'd be very close at lower ISO and close at high ISO..

And if printed at a reasonable size versus pixel peeping on a monitor, then I "assume" the results would be even that much closer in quality and thus even harder (if not practically impossible) to tell them apart..

My 2 cents..

BTW I have Canon DSLRs, never used a Nikon or Pentax DSLR (though have used Nikon film cameras)..

Good Day,Roonal.

While there are differences in the images from each camera, they tend to be subtle. It's easy to overwhelm the camera differences by how you process the raw image in your chosen developer..

There are also differences in how the raw converters will handle an image. Thus from a single camera you can get differences in the image by using more than one developer..

Now combine all the possibilities and then lay them out and I'm guessing that most photographers could no longer identify the camera or the raw converter..

Roonal's observations also apply about using similar quality glass.....just one more variable making for an infinite variety..

Settle in on a camera that you like. Go to that forum and they will help you pick up the best lens that you can afford and then try out a few of the raw converters, pick the one that you feel comfortable with. The combination will probably be more than sufficient..

I have an Oly E-1, 14-54mm and Lightroom and the combination far exceeds in flexibilty and quality my abilities as a photographer..

In addition to what you mentioned, I assumed that the sensor sizes are comparable. Now if I use similar setting for all (e.g., white balance, saturation, tone curve, sharpness), and tweaked exposure, brightness and shadows, should I get closer results (in terms of looking, details, etc)..

My 2 cents..

Many thanks !.

Thanks LM1 for your advice ! But, I have some more questions below..

Did you use ACR? If yes, is there any differences between, Adobe lightroom and Adobe ACR? Did you also try LightZone or Silkypix? Do you have any comment or observations?.

Do not use ACR..

As I understand Lightroom and ACR give similar results, it's just the interface that is different. Lightroom is, in my opinion, more intuitive..

Played with LightZone and Silkypix, and of course the manufacturers own converter (Studio), preferred Lightroom but thought Silkypix was a close second..

Most raw converters have a free download and trial period. I suggest that you try a few and pick your own.A member of the rabble in good standing...

Yes - I made that same assumption, but failed to put it in writing. You want to compare cameras that are in the same league..

Now if I use similar setting for all (e.g., whitebalance, saturation, tone curve, sharpness), and tweaked exposure,brightness and shadows, should I get closer results (in terms oflooking, details, etc)..

Well I think you would have to tweak just about everything for each camera, but once you did I think the results would be very close..
