I process my photos in PSE 15 RAW. If I save my photos from RAW to JPEG does it degrade the RAW.

No, the raw file isn't affected.

I here you loose info. If your worried about to , make a copy of original & save the copy to jpeg. Look at the size of the 2 files.

You are talking about multiple edits of a jpg. OP is talking about the raw file.

I never seem to get it right the first time. What I.need to know - will the print be better if I print from the edited RAW file or the converted JPEG file.

Here's an article:

Are you doing the printing yourself? Does your printer recognize the edits you made to the raw and is it able to print? What size print are you making?

When you save as jpg in Elements you have several choices regarding resolution for image quality:

If you print and then decide to make changes, re-open your raw file, make your adjustments, then create another "save as" jpg. There are other file types you could save as (tiff, for one), but I suspect you are not making prints large enough to notice any difference in quality.

You can't print directly from a RAW file - it has to be changed, either by you or the camera or the printer, to a printable file. Jpeg is one type of printable file, generally considered "Lossy" because the RAW info is compressed and some is left out. If you go from RAW to a .Tiff file the is no compression, and no loss of information. Consequently, .Tiff files are larger than .Jpeg files.

In the link I provided is this:

Direct Printing of Raw Files
In the past, photographers had to convert their raw images into JPEG or TIFF format before they could be printed. However, the growing popularity of the raw file format has encouraged several printer manufacturers to include facilities for printing raw files in some models in their printer range.

(not that I believe everything I read on the internet )

The above statement is essentially true. Note that it isn't really the RAW file that cannot be printed but the raw sensor data. A RAW file also contains a JPEG image that can be printed.

The rest of your comments need correction.

"Jpeg is one type of printable file, generally considered "Lossy" because the RAW info is compressed and some is left out. If you go from RAW to a .Tiff file the is no compression, and no loss of information. Consequently, .Tiff files are larger than .Jpeg files."

A JPEG file does not contain compressed RAW info. Raw sensor data is encoded using a Bayor Color Filter Array. To make a JPEG that data is converted to an RGB Bitmap. With a JPEG file format the bitmap is necessarily compressed, and it is always a "lossy" compression. That means the original bitmap derived from the RAW file that was displayed on screen by your RAW Converter will not be exactly what you later see when viewing the JPEG. Close, but slightly different.

If the output file from the RAW Converter is set to produce a TIFF formatted file it is also true that it shows, and saves, an RGB Bitmap. But the TIFF file can be compressed with "lossless" compression. The image originally display and the image later seen from the TIFF file are exactly the same, right down to every single bit.

Some printers can print from raw files, but they convert that raw file or more likely extract the embedded jpeg from that raw file. The article posted quotes "Lightroom 2" and is obviously several years out of date, and has left out the important info on how the printers tackle raw files. The fact that the author is saying the raw file will print exactly the same as a jpeg lends credibility to the jpeg extraction rather than conversion.

They print the JPEG that is embedded in each RAW file. It's not as if you get a distinct RAW conversion that is unique or better than that JPEG straight from the camera. Instead it is the JPEG from the camera and not the raw data.

Ah, that makes sense! Thanks

No, that is not necessarily true. Please do your research properly, FLoyd. Your assertion is easy to disprove.

As you say correctly, it is complicated, and clearly the sensor data has to be transformed to some kind of bitmap format to be viewed or printed, but it is most certainly NOT always the embedded JPEG. It depends upon the method used to transform the data.

JPEG - the version that is uniformly used - is an 8 bit format. Many raw files are 14 bit data, and many printers support more than 8 bit capability. A transformation from sensor data to a bitmap is a necessary thing, but a JPEG is not actually required, nor is it always used for every purpose. It may be a convenient format for preview purposes, but is not actually necessary, nor is it always used. It depends upon the camera, the printer, the printer drivers, and anything else that sits in between.

How's life in the dark (or the "civil twilight") in Utqiagvik - didn't Barrow just change it's name back to the original name? Are you looking forwards to sunrise in a few days time? Perhaps it will bring a new dawning of enlightenment.

With the advent of the new year, please stop spreading misinformation.

Printers don't do RAW conversion. They extract the embedded JPEG. As advertised
they print from the RAW file. They do not print from the raw sensor data, nor even look at it.

And while there was some experimentation with print engines working at 16 bits it has turned out to be less than useful. Printers don't print pixels, they print dithered lines. No printer works at 14 bit depth nor with Bayer CFA encoded data.

The discussion you are responding to was about printing directly from either a camera or the memory card, using the RAW file, and absent a computer. Stick to the topic and cease the silly effort at being antagonistic.

Incidentally, if it makes you happy to know, I do not use JPEG formatting anywhere in my printing workflow. I use the TIFF format.

Respectfully, I think your perspective is too simplistic and inaccurate to support your absolute statement. It only needs one example to disprove it.
