Who cares?
What you are describing is simply what the software needs to do to interpret exactly what the sensor took in the first place (raw).

Interesting how "exactly what the sensor took in the first place" can look so different when interpreted with no user input by three different raw converters. One of them even found a little more sky.

The information that to display a raw image requires considerable processing is worth knowing if only to dispel the myth that raw files look dull and flat when first viewed unprocessed. They might depending on the software processing them and they might not depending on the software processing them.

When the camera displays a photo for review on the back screen is this a jpeg or something else


It's a JPEG. Even if the photographer is shooting only raw it's a JPEG. Raw files have copies of the camera JPEG embedded for that specific purpose.

It doesn’t matter if you shoot RAW or JPEG, you don’t have to do post processing on either one if you don’t want to. However, if you shoot JPEG and choose to do a little post processing, you will be using the same basic procedures as you would if you shot RAW.

This is not entirely correct. If you chose to process a JPEG you'll be dealing the the processing already applied. For example go back to this post: https://www.uglyhedgehog.com/t-698929-4.html#12283857 and look at the 5th photo in the sequence. It shows the SOOC JPEG from the camera. The camera was set to auto-WB and that yellow wall threw it off. The JPEG is processed then with an incorrect WB. Setting the WB in a raw file is typically a simple one step operation. That won't work if you have a JPEG with a WB already set and you want to change it. It's much more difficult to do. Again the same if the JPEG has been processed with a tone curve you'd prefer wasn't used. Setting a tone curve from scratch with a raw file is again trivial, but trying to alter an existing tone curve to different values can be maddening.

One of the reasons I shoot only raw is to reduce all the time spent at the computer processing and all the extra work involved if I had shot JPEG. It takes more time, and more skill to try and fix a JPEG than it does to just process the raw right in the first place.

The difference is that RAW gives you more to work with so you can do more refined post processing. Why do you use a DSLR instead of just your cell phone? Many people achieve excellent results with their cell phones and are completely satisfied with the results.

Most of us use a DSLR, or something similar, instead of a phone because we can get more information, more detail, and more control from the DSLR than we can from the phone. Just take your pictures the way that satisfies you, JPEG or RAW, and don’t worry about what others are doing. If you’re truly interested in why some people use RAW, then listen to their reasoning and after listening, you make the decision what is right for you. There is no right or wrong answer, just your preference. Use whatever method gives you the best results and be happy with those results. If you are not happy with you results, then by all means ask for help and listen to the advice you are given. It is up to you to decide what works best for you.

Sorry but you can still PP a lot in Jpeg!

Yes, but why do all that extra work? I shoot only raw because I don't want to spend all that time sitting at the computer processing photos. It takes much more time and more skill to process JPEGs than it does to process raw files.

Sure you can PP JPEGs but I'd rather process raw files and use the extra time to get out and do more shooting.

(Or do other things. )

I must be one of the few people who only "process" what I'm going to use for something.
I don't process every image I take. No need for me to do so.

Uh huh... and when you take a raw image that is 30MB ... and you also take the same image with JPEG...you get a file 1/10 +/- the size.

You can't put the info back into the JPEG.

There's a big difference.


That's another choice made by the operator. And it's one that I never choose. If you are stingy with memory and choose to save a lower resolution, more highly compressed file, then I feel like you pretty much deserve what you get. I don't choose that. I save full resolution files with minimum compression. They are about 40% of the size of a raw file of the same image, and very little fidelity is lost over numerous resaves. The choices we make do make a difference.

Clearly we are at the point in this discussion where stubbornness rules and no one is learning. My process based on facts continues to work fine. At this point, I'll just leave the group to their own "wisdom."

If it works for you, don't fix it.

I process every image I take because they go into Lightroom for organization. The processing happens as a side effect, even if I don't make any adjustments (beyond presets).
But having said that, I frequently crop photos, which some consider part of processing. I do not feel bound by the standard camera aspect ratio. Sometimes the composition demands something else.

Some subjects will never get a consensus because everyone likes to edit their own way (maybe 50/50 today, 60/40 tomorrow?); some think RAW editing is more trouble; some don't know what they can/can't do <easily> between editors. What works for some may be of no interest to others.

Many don't search, because they're unaware a subject may be previously covered if they've never seen the subject before; the comments may be old or they would like a quick response instead of trying to fine previous threads (less effort). Some people aren't worried about the "data" difference between RAW and JPEG and some don't understand the conversion process (what may be lost).
Some topics will never ever retire.

What's better, camera A or camera B?
Editor 1 or editor 2?

Quite agree kind Sir - we are of like mind. However, as far as I can see, no one ever mentions what happens to the image they produce. I see two distinct groups of photographers - Professionals and Non Professionals. Within the Professional group there are a number of sub groups for example Weddings, Media, Real Estate and more. You would expect, I think, that Wedding photographers need good skin tones and overall colour accuracy so would shoot RAW as a matter of necessity. Media photographers however I doubt would need that accuracy -- they want to get the shot and get it accepted then out to get the next - no time for editing!?!? Jpeg best for them. Real Estate - dynamic range would be their requirement with colour not so important. Time probably not an issue so they would shoot RAW. I don't know for certain but I suspect output for most sub groups would still be to jpeg.
Now as to our Non Professionals - well what do you do with your photographs???? I'm sure many are like me and the photos reside on our computers and are displayed in screensavers. I often sit and watch the world go by on my iMac screen. Many (most) of my photos are of my travels. RAW for me is quite unnecessary - I set my camera to give the best jpeg SOOC. Strangely back in the days of film I spent hours dodging and shading and even cutting and pasting then re-shooting - this the original post processing. I still have hundreds of slightly different prints of the same negative of my babies. Can't bring myself to throw them away - keep thinking I'll scan the best then edit them - maybe ....... Now, if I have a shot that's not quite right, then I usually delete it rather than spend time editing it.
If you sell some of your photos or maybe enter competitions then probably RAW is for you. Yes I think neither RAW nor jpeg are better - it depends more on your output requirements. If you like editing then that's your output - be happy with it but don't suggest its for everyone and look upon those that don't agree as some kind of Neanderthal. "Listen" to Messrs Chg-Canon and LarryPage - they know what they're talking about.

My organization is in subject directories on the hard drive. I don't use a cataloger.
So once I copy them to the disk, no further action is needed until I use an image.
Yes, cropping is "processing", but not in the sense of adjusting parameters. And one shouldn't feel bound by the native aspect ratio. I've seen images where there are multiple good crops in them. For me, cropping is done when I use the image. Until I use the images for something, my images only have the presets in the camera applied.

Definitely a non-professional here!
Many of my photos are simply mementos of a place or gathering.
I can take a couple of hundred images on a trip to Acadia, but I would never sit and edit each one.
Some people love making each and every image they take look great. Used anywhere or not.
That's their prerogative.

Yea, I've deleted a bunch also.

How much can you fine tune a JPEG image vs RAW? I don’t really enjoy post processing RAW images, and don’t have an eye for it. How much control do you give up using JPEG.


I defy anyone to identify a jpeg and a raw image, shot with same equip of same subj, both pp’ed by an experienced user of the s/w (eg., photoshop) and discern which is which. Just my thoughts.
