The simplest answer just may be the best answer - if you can process a raw file to look better and be more complete than a camera's jpeg - is there any reason on earth why you'd want to settle for the jpeg out of the camera?

Lots of reasons, including the value of my time, the definition of 'better', and the veracity of my work. I am perfectly willing to be grouped with the professionals who cover the Olympics - but like them, I don't 'settle' for SOOC; my workflow, like theirs includes dealing with issues such as 'plumbness', color levels, and sharpness.

I have made six prints in my entire life.

With film I made slides to be projected on a screen; now I make JPEGs to be viewed on a screen.

JPEG created by the camera, as I use it, loses no more than JPEG created by an editor from a 'raw' file.
I follow the same workflow used in covering the Olympics; my orientation also happens to be the same.


BTW: this isn't a big deal, but this is the second time you have used the word 'loose' {the opposite of 'tighten'} when you meant to use 'lose' {the opposite of 'find'}.

Hi sorry about the typo.. I make and sell prints, as this is my business full time, that is why I always use RAW, just to make sure that my high resolution prints are the best I can make them.. My comments pertained to making 8x10 or larger prints. It is different on screen with a low res. of 72 compared to prints of 300dpi. I hope my misspelled word hasn't up set you....

Scotty, you caught me on the Color Space part, as I was thinking WB, but hadn't had any coffee yet.

As for ADL, no effect on RAW. ADL only works on jpg format. At least in Nikon cameras. As for mistakes in exposure that either clip highlights or block shadows, very difficult to recover either. There is simply no data there with which to work. The best practice is ETTR/EBTR. Watch the highlights and the shadows will take care of themselves.

We already know that Active-D lighting is for JPEG straight from the camera. That's the whole point. If you ever used it you would understand that it does highlight and shadow recovery in the camera. It's just a little more arbitrary (harder to control) than you might do yourself on your computer when developing from raw.

As for ETTR, that's an entirely separate discussion. You don't have to use it at all if the scene's DR is narrow. In fact, it can get in the way and confuse things if you are not considering both ends of the dynamic range (DR).

The bottom line is that you don't want to overexpose the highlights in either case - wide or narrow DR. You can accomplish that by watching the only highlights. If an average reading produces no blinkies then the DR is narrow and you don't need ETTR. If there are a lot of blinkies where you want detail, you have to reduce exposure.

If your DR is narrow, ETTR might lead you to an exposure that is greater than the average. You will have to reduce the gain (Exposure) in the raw conversion and you may need to recover some highlights and shadows.

If your DR is wide, your exposure is just as likely to be less than the average. You will need to increase the gain, recover highlights and shadows.

You and I use both film and digital. We are both qualified to compare them. Those among us who have only used film or digital cannot really make an informed judgement.

By the same token, until you are competent using both raw and in-camera JPEG you are not really in a position to compare one approach to the other.

Try selling an image to Reuters. They will only take a JPEG out of the camera because they don't trust "Photo-shopped" images. They are not alone.

There are lots of cases where truth is more important than beauty.

DPI resolution is meaningless; the important measure is linear pixel count but that is a different thread.

The important take-home lesson from this thread is that different people have different aspirations, which lead to different needs. At one time I designed, implemented, and tested software sold to the US DOD; every project began with a careful determination of the needs to be addressed; you have to understand the customer in order to recommend a solution. Similarly, 'raw' meets some needs; I thought the purpose of this thread was to identify those. Some people want to say "Only for the arrogant." Some want to say "Everyone who wants to do something worth doing". The correct answer is somewhere between these two extremes.

My boss at one time was a talented Mechanical Engineer who happened to be dyslexic; before he sent off a report, he would have someone else proofread it for him. He told me at one time that his career was held back because others noticed his writing issues - I mentioned your 'loose' issue in that same spirit.

Scotty, someone had mentioned ADL and I wanted to clear that up in one post.

As for ETTR/EBTR, that works for any exposure. It's a simple solution to not blowing highlights. As such, it also loads the lower end of the range with data. As a side effect of this, noticeable noise is reduced considerably. It has never gotten into anywhere near confusing. It just works. I've proven it time and time again.

As for bracketing, it's supposedly an Ansel Adams quote that states, "those who bracket don't really know what they are doing".

As with any client, if I were contracted to provide images to Reuters, I'd provide them what they requesting. No argument.

You would have to first learn how to shoot a JPEG properly.

. . . Professionals use LR and shoot in RAW. I know of no professional that shoots in JPEG, unless shooting for fast buffer time, or news journaling.. Studio work is always RAW...

Professional sports and news photographers shoot JPEG because they can submit their images from the field and being first to print or view is paramount.
canon Lee wrote:
Again, I cant understand why anyone would want to shoot in jpeg. I hope its not due to the price of LR raw converter program.

Lets face it. If you see an image on the internet, you can't tell if it is a JPEG straight out of camera or a JPEG that is the output of an expertly processed RAW file. And 99% of people looking at a printed photo wouldn't be able to tell if it was printed from a straight out of camera JPEG or from the output of an expertly processed RAW file. But if they were comparing two such prints, they would not fail to notice the difference in quality. Also, consider that learning to post process well takes considerably more time than learning to operate a camera.

I am not a professional. I don't shoot JPEGs. I only shoot RAW because I have time to post process, I have time to continuously improve my post processing skills, I value quality over quantity, and I would never circulate an image in any format that is not the best I am capable of producing.

A few years back I did a project for the Coast Guard to be sent to Library of Congress. Not only did they insist on film, it had to be on 4x5 sheet film. They did not even want any prints.

As photograohy is one means of being creative, artistic, the idea of 'fixing' converging railroad tracks might produce some astonishing side effects. When Photoshop makes square things that aren't all bytes of the image get changed. Just another of my strange brain farts.

I wouldn't 'fix' keystoning if I started off with a 'raw' file; I also wouldn't 'fix' railroad tracks that seem to converge as they recede in the distance.

canon lee used dpi in the context of making prints. Printers use dpi.

Always shoot raw, Adobe RGB. The histogram will be to left on a darker images and to the right on a lighter images. Check for any black areas or flashing white areas in your image previews. If in doubt shoot another darker or lighter shot. Always save your best images as 16 bitt Tiffs.
