Hi, jmcD,

Here's another "take" on the " jpg -RAW comparison" that some of my students and workshop participants have found useful:

The RAW data collected by your camera at exposure is not an image data file comparable to the JPEG file that your camera selects, copies, and "cooks down" from that original, inviolate sack of RAW data.

The 12 bit or 14 bit "RAW FILE" your camera delivers is simply a guarantee that that sack o' RAW data can be repeatedly "worked" by the RAW converter of your choice to come up up with a practically unlimited number of raw versions/ interpretations in a 16-bit environment , each with multiple thousands more options of interpretation than posessed by that little 8-bit RAW file that,admittedly, doesn't look too bad straight-out-of-camera (SOOC) but which is served up as a small "medium-well-done" hamburger rather than with all the glorious inate potential of a whole side of RAW U.S.D.A. Prime beef that never looses weight as new entrès are prepared from it!
Damn...now I'm hungry...salivating...prime rib, please -medium rare!

A RAW file contains all of the information that the camera recorded. If the camera converts this to a JPG file, some of that information is adjusted to correct exposure, contrast, color, etc. Some of the information may be lost and irretrievable, such as detail in the highlights and shadows.

If you don't want the camera to make arbitrary decisions for you, work with the original RAW file and make your own adjustments. It's a little more work and you might not want to do it for all of your images but it provides you the most control over your image.

Most current photo editing software can start from a RAW file but if you are not using a Nikon or a Canon, try before you buy.

I consider a RAW file to be the digital equivalent of a 35mm negative. It's an archive file that you can always go back to. I'm currently using an open source program called UFRaw to process my .NEF (Nikon RAW) files. I prefer it to the software that came with my D5100. UFRaw saves to a format called .PPM that can be directly exported to GIMP - my editing software of choice. (also open source)

The RAW file format provides more image information giving more elbow room for later image development. A larger file size results.

The JPEG file format derives from the RAW file while in camera according to camera metering and settings. This in-camera pre-processing discards some image information. But this discarding gives a smaller file size.

That said, some experienced photographers will shoot in the JPEG file format when they can control lighting and color calibration to produce a well-exposed image.

Photographers who shoot many pictures of an event (like a wedding) will use the JPEG file format to minimize processing time in order that they may write an invoice sooner.

Please know that shooting in RAW requires more processing afterward, first in the RAW software and then in the photo editor to finish the photograph. You will spend more time and effort going this route but potentially will have more control over results.

You could try shooting with your camera set to RAW + JPEG. This setting will give you two files, one in each file format.

Of course, with this setting, your images will then take up more space on the hard drive, yet consider the very low cost of computer storage these days. You could just buy, say, a 4 terabyte external hard drive to save all your photo files.

Finally, please consider one day when you have gained more experience in shooting and in image processing, you may wish to return to your earlier images to process them for their value in light of the passage of time. You will thank yourself for having a RAW file of those precious images.

Good Morning,
Raw contains all the info that was recorded when you clicked the shutter. Very good to have that but not in all cases.
When shooting something important where images have the possibility of being printed large then one should shoot in RAW. If one is shooting something that will ONLY be used for snap shot purposes one can easily get away with jpegs.
However one thing to think of is RAW conversion only takes a few minutes so it is easy to convert so why not let yourself to have one less thing to think about and shoot everything in RAW.
Someone stated that .dng files were proprietary to Adobe and that is wrong. Hundreds of applications use this file designation.

RAW....

If I shoot Sports = jpg... For one thing, the speed of the shutter is faster and I get the shot(s). However, where "action" is not really the important factor (i.e.= Portraits - Landscape - wildlife - and events) I always use RAW. Remember that You are the photographer, not the camera.

J.M, this was a great set! I really like 1 & 2, the DOF gave them a terrific diorama feel. The post work on #3 is fantastic, just the right amount of HDR. If you don't mind, I would like to show you my favorite train shot.
Thank you for sharing. Bill


Would love to see your train shot.

Does anyone remember Barack Obama's great promise of the campaign of 2012? He did not make a promise to America nor to Americans. He did not make a promise to fellow politicians.

Unlike so many of his promises, he is keeping this one. His promise was to Vladimir Putin of Russia .

What is Obama doing to keep his promise to Putin?

Everyone remembers the hot mike incident in 2012 when Barack Obama pleaded with Russian President Dmitri Medvedyev to give Him time until the election. After the election, he promised Vladimir Putin, through Medvedyev, he would be more "flexible."

Now we have seen this flexibility.

Barack Obama is going to spend almost $700 million dollars of taxpayer money to buy Russian helicopters for the Afghan Air Force. But wait. Just like those TV commercials, this gets better.

When Congress passed the 2013 National Defense Authorization Act, it had an interesting provision. Congress included, as a part of that law a prohibition on the United States buying helicopters from Rosoboronexport, the Russian manufacturer of the Mi-17 helicopter. Unfortunately as always happens, when such laws are passed, Congress always gives the Regime an escape hatch. The law stated that Obama could buy from Rosoboronexport if the Secretary of Defense certified it was in the interest of National Security. And of course, the Secretary of Defense, Chuck Hagel, a man committed to destroying the US military immediately signed off on that certification.

Where do we even start with this one?

Congress is outraged over this with Senators and Representatives from both parties writing letters about this. Of course, this is Congress' fault for allowing a law to be written With such an escape hatch.

More importantly, Americans need to be asking just what the hell the Obama Regime is doing.

Why are we spending $700 million dollars with a Russian Arms manufacturer? Why are we even giving the Afghans these Helicopters? If we are going to give them helicopters, which we really Shouldn't, then why not give them American made helicopters and put Americans to work?

Even if we are going to give the Afghans Russian helicopters, the ones we are giving them are an old Cold War design. There are hundreds of used MI-17 helicopters floating around the world. Why are we paying to give the Afghans brand new helicopters?

In the era of the Sequester, isn't there something better we can do with $700 million?
American Medicare cancer patients are being turned away from hospitals and are being denied life saving treatment because of Budget cuts. The American military is being gutted to the point of ineffectiveness because of budget cuts.

Or consider this. The United States Air Force is grounding 17 squadrons because of $591 million dollars in budget cuts. Our Air Force is not able to do its mission because it lacks the money to fly but we have the money to give Afghanistan $700 million dollars In Russian helicopters.

And this is where Barack Obama thinks we should spend our money?

Most people reading this story will not have heard about it. Why? Because the Obama Propaganda Media is moving in lock step To make sure there is no bad news that might damage Obama's presidency.

This is a story that should damage him and outrage every American.

Ask your Senator or Congressman why this outrage is being allowed and take a moment to share this story with your friends.

The only way we will ever stop Obama is if the American People know what he is doing.

This guy is the biggest embarrassment our once great county has ever known!
