It is and I've tried to help you understand.

This is completely false.
A Photoshop document does not remain a raw file.nikonbrain wrote:
How it is Non destructive to the original file this book explains this .Why do you keep badgering Me ?
I'm trying to help you understand. I've already explained that the term non-destructive as I'm using it does not refer to preserving the original file or the original data. Non-destructive can also refer to the editing workflow and that's what I'm talking about.

I'm listening to you and noting how wrong you are.

anyways I was only correcting a statement about that editing a raw file as destructive as it clearly is not as long as you properly "save as" and give it a new name and not save which overwrites the file .
And I've explained to you more than once now that I'm not using that meaning of the term non-destructive.

These are fine books for learning a raw workflow they may help others , this was not aimed at you although you seem to think it is .The 2nd book I have not read but I am interested in Neural filters that seem to be part of version 22.4.3 of Photoshop that I just updated to .Have a pleasant experience in your photography travels .
Maybe an example will help you understand. NOTE:
RAW WORKFLOW I've acknowledge that PS is a 100% non-destructive editor for RGB image files. I have never been talking about that. I'm talking about a non-destructive raw workflow.
Here's a link to a raw file that you can download and if you like follow along:
https://www.dropbox.com/s/4n55pfpek1fwaw3/_MG_0083.CR2?dl=0Using PS you first have to open the raw file in ACR. There you have editing work to do. You have to set WB. You have to select an input profile. You should tone adjust the image. Maybe straighten the image. First image below is that photo basically adjusted in ACR. Look at the photo and you'll see a tree branch on the right side -- it has to go. You consider ACR and it's ability and decide that to remove the tree branch you need PS. So you pass a smart object from ACR to PS for further editing. NOTE: [PS in this regard is better than all other options since by passing a Smart Object you will retain access to the original ACR edits applied to the image].
In PS you need to clone/erase/content-aware-replace the tree branch. You can't do any of that to the Smart Object. To do any clone/heal/etc. work in PS you have to create a raster layer. Most of those books will tell you to create a blank layer above the Smart Object layer and do the clone/heal work there by setting the tool to Sample Current & Below. The second image below then is the photo with the tree branch removed. So far so good.
You put the edit away and go to bed. In the morning with fresh eyes you look at the edit and it occurs to you that one of the other input profiles in ACR would have been better.
In a 100% non-destructive raw workflow you should be able to make that change and see how it looks. Unfortunately you used Photoshop which is not 100% non-destructive in a raw workflow. Let's see what happens. Dbl click on the Smart Object and you'll be taken back to ACR where you can change the input profile. It's a Canon raw file and originally I used the Neutral input profile -- let's see if landscape is better. Lots more contrast and saturation with that profile change. I like it
BUT WAIT! what the bleep is going on in the sky where that branch used to be?!!!! Looks like I have a destructive workflow element. OUCH! I've got to re-do all that cloning work because the raster layer didn't update the change I made via the Smart Object.
That sucks!What about other software? Let's do the same thing in C1. The fourth illustration below is the same image processed in C1 with the same tree branch removed in C1. The left side image is the neutral profile and in the right side image I changed the profile as well as the sky color
and the cloning work to remove the tree branch updated the change. Unlike in PS I don't have to do the cloning work over and that's a non-destructive raw workflow.
Do you understand now? If you think I'm wrong download that raw file and show us how to do what I did in C1 in PS.
