Sorry to continue the conversation, but maybe posting a photo will help. This is a photo, shot as raw, uploaded to my Mac and imported into Photos. I have exported the origin file to my desktop to attach. This is my first attempt to post a photo....hope I did it right.

The file is a NEF file, Nikon's version of raw. Not sure what you are wanting to do, but typically, a JPG is used to post here. The file is not displaying, as a result.

Do you have a question about the file you posted?

When you attach a file select Choose File and then click on Store Original, finally, click on Add Attachment and you will end up with the image displayed like I just attached from my phone. You cannot preview an attached file and you cannot display a raw image, if the file you attached was a raw image it's best to export it as a high resolution jpeg first. I believe the jpegs need to be under 20 megabytes in size.

I had to download it and then open in Photo Shop to see it.
Just what kind of comments etc are you looking for?

Trying to understand responses in an earlier post I made. "Processing Raw". I thought a photo would help.

WOW confused again........
So, I shoot a photo in raw, upload it to my Mac and an external hard drive, then import it into Photos. Even though the data information file for the photo reads raw, it is really JPEG? When I load the same photo into Light room, or Affinity, I can process it as a raw file. Does that not make it a raw file?

ALL raw files coming from cameras *contain* JPEG previews. These previews are used to display the file on the LCD or OLED screen on the back of your camera. They are also used to display a thumbnail in your operating system. They may be used to display an image when you open a raw file, before the software has a chance to fully convert the raw data to a better view.

The raw file is a "wrapper" of sorts. Inside every raw file is at least one (sometimes two or three different sizes of) preview JPEG. Then there is the EXIF table of information about camera settings (the metadata, or data about data). Then, there is the sensor array output, which is the raw data your application will process into something viewable — some sort of bitmap — that can be saved in an actual image file format.

When you make an exposure, your camera uses its current menu settings to process the image with its own JPEG engine. Those menu settings offer you a lot of PRE-PROCESSING control. What they don't (usually) allow is the use of the full 12-bit or 14-bit sensor data to make "after the fact" changes to an image. That's why raw files can be processed to make JPEGs look so much better than they would if you just relied upon the camera for processing.

There is far more dynamic range in a raw file than in a JPEG. A JPEG contains about 5.5 usable f/stops of range, while a raw file from the best cameras captures 13-14 stops or so. Post processing "compresses" the tonal range of a raw file into a printable or displayable range of tones.

EVERY software program used for post-processing raw files will display some sort of bitmap, which either is decoded from the JPEG in the raw file, or is created within the software itself as a proxy file. This is necessary because monitors are at best 10-bit devices, and usually just 8-bit devices, so you cannot display the full range of tones in the image.

I had absolutely NO PROBLEM opening it in PS CC. It opened up just like any other RAW image from a camera hat is supported by PS.

Exactly. A high-resolution jpeg with the EXIF data and attached with store original checked is probably all we need to assist the OP. I personally have no desire to download images and open them up in my raw program just to view them. Now, if the OP is specifically asking us to do that so he can see what our take on post processing his Image would be, that's another thing, but he didn't ask for that.

Nor did I, but it wasn't displayed on the web page as I assumed the OP wanted. Lots of folks here do not have PSCC.

I'm sorry, is there a specific question in there somewhere that we can answer?

I too won't bother downloading a RAW file.

So what is the problem? Just posting this attachment doesn't seem to demonstrate anything.

Whatever you are using to view the raw file is creating an interpreted VIEW of the raw file, not necessarily a JPEG.
JPEG files are transportable (viewable here, on-line), raw files not so much.

Charlie, nearly ANY file can be processed, but some give more latitude in the adjustments that can be made. JPG files are typically reserved for 'output', meaning, a file to be shared after the processing is complete. At any rate, just because you can import the file and process it into Lightroom doesn't make it a raw file.

Raw files are comprised of the data taken directly from the sensor of your camera. If you set your camera to produce JPG files, the camera takes that raw file from the sensor and processes it in camera to produce the JPG. For those who want to process there own raw files, they must set their camera to produce (to the SD card) only the raw file. Then, those raw files can be migrated to a computer and processed with the software of choice.

Hope this helps clear things for you a bit.

By the way, that's a nice shot!!

I don't bother playing with posted raw files either.

Nope. You uploaded the raw file which will show absolutely no processing at all. To post a pic on UHH, process the raw file in your computer using whatever software is at your disposal and then export or save that finished file as a jpg file. You can rename it or keep the prefix the same as the raw file. Then use that jpg to "Choose File, then Add Attachment and don't forget to use the (store original) checkbox. Done

This is your file processed in ACR and then opened and saved in Photoshop.
