I’m not quite sure what you mean by “not mathematically editable”. Any file can be edited. Now to make usable edits that don’t corrupt the file, that can also be done but it isn’t because it’s complicated and since raw files are proprietary and even change from model to model within each brand it would be especially difficult to develop a product that is fairly universal. It would be pretty simple to edit any file with a hex editor. The hard part is knowing what edits to make.


I agree that is a regrettable sentence. I was trying to say ACR cannot modify the original raw file to save the edited image. Bridge apparently assumes if you select a file again you want to start with applying the previous edits. An easy way around this problem is to copy the original file to a new named file. Do not copy a .xml sidecar file because that is probably how Bridge knows it has been processed. Now I don’t use Bridge often and I am 2,200 miles from homes and can’t verify the existence of the .xml file.

If i take several shots for a pano or hdr and process them in LrC with cmd-r or cmd-h LrC generates a dng. That’s the only time I use the dng format. I don’t know how to make LrC generate a different format.


A common behavior but no harm no foul. You still have the original raw files and yet you can the resulting merge as if it were raw but I have no idea how it does that. It seems to work great so I don’t think about it. Before merging I finish all my global stuff to one of the originals and sync them before merge.

Did you try checking the read only box and repeating test?


I think I misunderstood cahale’s observation. Raw files are not marked with the Read Only property. There is no reason to modify the actual image data within them. And doing so may corrupt them. Several years ago I changed the privileges of the top level folder to set them as read only and LrC ran normally. For software types I set the equivalent of chmod to no modify and let her rip.

LR, for me, was not that difficult to learn. And I have a limited “hard drive” if you get drift.


I agree. BUT then I bought LrC because of not in spite of the database Library module so I may be a ringer.

Databases are the go to basis of user displays where the user is not required. to understand the details of how data are stored. An example is TurboTax and other tax prep software which is built with the ubiquitous SQLite engine that LrC uses. Searching, sorting and selecting are tasks that databases do for a living. If the Library catalog is not for you then use ACR in Ps. It is the same functionality. It is a bit more cumbersome because have lost the ability to synchronize adjustments across a number of images.

I can’t understand why people would find the develop module complex is rich in function perhaps but not complex. You can grab a slider to see what it does and simple put it back to where it was if you don’t want to do that. And again synchronization across versions of an image and the the ability to try a full alternate is more cumbersome .

"RAW files are read-only" Really? Screen shots of the properties of 4 different "raw" files as they appeared. I changed nothing. And of the 4 will open in Photomatix, which doesn't do anything to the original raw file. Sony's proprietary Edit, however allows selection of whether to save the ARW as edited, or as original. If "as edited" is selected, the resulting ARW file IS altered, and no provision is made for retaining the original. That's why we (or I) back up.

Remember, RAW files are read-only; Adobe writes nothing into any of these proprietary files. The only issue is re-discovering the process of undoing the edits; not creating additional files for no actual purpose.


To elaborate…
A raw image is mathematically not editable you can only edit how you process it. “Only a camera can create a raw file.”

The metadata in in a raw file is written in the Exif format which is a very fragile format that is easily broken by attempts to edit. So Adobe wisely will not attempt to add to metadata in a proprietary raw file format. An exception to this rule is date and time shot which is stored in a ridged safe format. The .dng format is an Adobe format so they will add metadata in that case. If you Lightroom (possibly other software) will, if you elect, store the edit metadata in a sidecar file in addition recording edits in its catalog. I don’t know for sure but assume ACR with Bridge does the same. Photoshop records ACR edits in saved photoshop files.

So I suppose you have to copy the original raw file with a different name to convince bridge that it is indeed a different edit.

According to PhotoPills my camp on Lake Ontario is nearly centered within the band of total eclipse and we have a clear viewing path for the entire event so my plan is as follows:

Aggressively attack PT after knee replacement so I can drive for sure.

Pray for a clear sky.

Arrange lawn chairs appropriately.

Purchase high quality glasses.

Keep camera in bag.

Chill beverages.

Keep praying. Sacrifice chicken. Spin prayer wheels.

Enjoy watching eclipse or consume beverages while screaming bad language.

Look at and admire your posts of great shots. Thank you!

At the last visit with my PCP I told her that I wish I was 70 again (or maybe 75, I can’t remember).

Below is an article that you may wish to read...

TITLE: Hardware Recommendations for Adobe Lightroom Classic

....... The Puget System company specializes in 'needs' for Lightroom and they very freely 'share' their research with anyone who wishes to build their own computer.

Let me know if this helps in any way...

If you are serious about configuring a workstation these guys are top notch. The data they provide is program specific which cuts through the generalizations that often “sell” a brand. On the other hand this assumes you are willing and able to roll your own configuration. Since for 43 years before retirement I enjoyed a fine living mostly configuring systems in defense of our country (and allies) I eat this stuff up. I have been retired almost 17 years and absolutely out of touch with the state of the art (which takes maybe six months).

I worked with them to configure and build my current machine two years ago. They are more pricey than assembling as DIY but they have an engineering and manufacturing capability I cannot reproduce. For example their parts selection includes collecting actual failure data and. they have measured cooling designs. They actually take thermal photographs of your machine and provide them in a multipage data package. That sort of thing impresses me. I chose to drop $5K on a computer I wanted but didn’t need more that a camera I don’t need. Oh, I should add the resultant computer really performs and is virtually silent except when the fans in the GPU fire up.

However, they don’t do Apple nor laptops because Macs are not an open system and don’t play in this market and laptops just can’t compete performance wise.

Because you own some Topaz apps, we have a special offer for you!

Little do they know, since the stuff I “own” doesn’t float my boat and I don’t use it I am not going to renew my not a subscription this year. I was going to download the latest version before renewal time in December but yesterday I flew to my daughters on the other coast returning in January. Oh well.


BTW I am in the Olympia part of 98516.

The OP, "mffox", wrote that he wants to "buy" Topaz Studio 2. Your link sends one to a section on Topaz where you can "download" the program but it would be useless without a "license key" which is no longer for sale.

I downloaded LR and PS, didn't realize I had to click on Camera Raw for it to download. Don't know if I can go back and get it


You may no have to. It used to download and install with either LrC or Ps.
