I agree that CS5 probably encoded the file in a way that allowed for the Lab color space. But since a lot of the files are opening in a lower resolution of only 900 pixels I have no choice but to rescan those. I have to have at least 2000 pixels at 300 PPI for printing purposes. Rescanning is not hard, just takes time. I will just have to save them in TIFF this time. I cannot use CS5 at all on my current Mac. It is not compatible with the High Sierra OSX. I actually had CS5 on a CD that I bought back in 2012. It worked fine on my older Mac, but when I had to upgrade to a newer Mac in 2017 the CS5 simply would not work. It kept crashing and giving me errors. At that time I contacted Adobe support about this and they told me that CS5 was never tested on Mac OSX newer than El Capitan. They suggested I switch to Creative Cloud, but I told them I am not renting a program. And Windows based programs will not even install on my Mac, so those would be a waste of time. That is when I searched for an alternative to Photoshop and found Affinity Photo. APh works just great with all of my old files except those in the JPF format. Like I said, it will be simpler to just rescan those old photos. I have a high resolution scanner so it will not be a problem. It will just take time. Thanks for the effort, but looks like rescanning is the only sure option of getting the resolution I need for those old photos. Perhaps APh will add the support for JPF in the future as the program gains popularity.

I've never used Corel. But I am not surprised.

As I mentioned in a prior reply, I save my files in LAB because it mimics the color range the human eye perceives. It also produces better print color than straight RGB because LAB uses a 3 dimensional color model versus 2D RGB. I have used this color mode for over 17 years without problems as far as printing. The current problem I have is strictly compatibility issues with the JPF format I saved some older files in. I originally chose JPF strictly to save computer drive space because JPF supported LAB 16 bit yet was half the size of TIFF. I obviously don't use the JPF format anymore. But because I have a lot of older files in the JPF format that is why I am searching for a way to convert them to TIFF but preserve the original LAB 16 bit they were first saved in. Since these older files are mostly old film photo scans I will simply have to rescan them if all else fails.

The LAB color in the original file is causing the problem because that is obviously not the right color output. These programs just cannot handle it. I will have to use the Preview App in my Mac to convert them one at a time and use APh to manually switch them back to LAB color. I am not going back to Photoshop. CS5 will not work on my current Mac, which is why I got APh. And I am not going to install Creative Cloud. I don't rent programs and I don't use programs that require an internet connection to operate.

Just tried XnConvert, which is from the same company that makes XnView, and it crashed when I tried to convert a 40 megabyte JPF into a 16 bit TIFF. I guess these 3rd party programs don't like my Mac.

I only brought this subject up again because I did notice that some people were able to convert J2K and JP2 files using the newest APh. So I thought that perhaps they did add the support, but I was wrong because it still won't read JPF. My guess is that Adobe has a special patent on JPF because when I saved my files in that format back when I had CS5 the JPF extension was the only option for JPEG2000 using CS5. I did a search and there is no 3rd party software listed specifically for JPF, but I did find a lot of 3rd party software for JP2 and J2K. That ImageMagick also does not support JPF according to its supported format page. I even tried one of those on-line conversion websites but they also said the JPF format was not supported.

Unfortunately that JPEG2000 plug-in is the only one I needed to work. APh pretty much does what I need it to do, with the exception of not being able to open JPF files.

The Preview App does not support LAB so it does open it in RGB. So I do have to use APh to switch it back to LAB after converting to TIF. Maybe I will find another program later that will work better. Anyway, thanks for the effort.

For some reason when I checked the one you converted it was showing a display resolution of only 72 PPI. Maybe it was the PhotoLine program that caused that, I don't know. Most of these are old film photos various family members took. They obviously did not know how to use their cameras when it came to focus. But they wanted me to preserve them since the photo prints are starting to fade. I will have to rescan the ones that somehow ended up with low resolutions. Here is one that has the original resolution preserved to show you what I mean. I have no idea how the others ended up with low resolutions since I saved them all the same way, unless it had something to do with the failing motherboard at the time. Moms_Dogs067.jpf

Jus thought I would check before I deleted all of these old CS5 files.

Here is the JPEG2000 plug-in I saved from CS5. If there is a way to use it in APh let me know. JPEG2000.plugin.zip

Yes, I am certain the original resolution was much higher than what is being displayed. It varied from file to file, but the minimum scan resolution was at least 2000 pixels when I did the original scans. I am beginning to think that some of these files might have been corrupted during the saving process and only the smaller preview image is being read by the program. I recall that during that time I was having trouble with my old Mac. The CS5 program crashed during some saves and a couple of months later the whole mother board failed forcing me to replace the MacBook with the newer model I have now. Before the CS5 started crashing I actually did get some JPF files saved that are in the 20 to 45 megabyte range and show resolutions of up to 4300 pixels. I think that is what happened. The motherboard was failing and that caused the CS5 to malfunction during the encoding causing the corrupted compressions of the JPFs. I will have to simply rescan all the photos that got corrupted and save them as TIFs and be done with it. By the way, I did find a way to convert it using the Preview App built into my Mac. I simply click "Print", and then in the print window save it as a PostScript. I can then open that PostScript file with Affinity and then resave it as a TIF in LAB color. I'll use that method for the JPFs that still show their original resolutions. Thanks for your efforts. At least now I know that it is quite probably that some of these old JPFs are simply corrupted and have to be rescanned.

I don't think you should waste your time trying to create an action for me. I have been playing around with the program and even though the colors can be converted it is still not working in one critical way. The resolution is not being converted properly. When I check the image data of the one you converted for me it only shows an image size of 900x800 pixels at 72ppi. I originally saved these files at 300 PPI and most of them were scanned at a pixel dimension of at least 2000 pixels for most of the images I scanned. Apparently PhotoLine is only converting the display preview image, which is 900x800. That means the original resolution is being lost in the conversion. So don't waste your time creating the batch action for me. It will only create low resolution versions which will be useless for printing since I need at least 2000 pixels at 300 PPI to make an 8x10 print. Sorry about this, but I may have to just rescan all of the images since these files can only be opened by Photoshop.

Guess that explains why the plug-ins I saved don't work. I might as well delete all of those old CS5 plug-ins if they won't work in anything else.

Don't worry. If necessary I will do them a few at a time. Might take a few days but as long as I can get them converted before the trial period of the program expires. Maybe Affinity will incorporate JPF in the future if they get enough requests for it. I do know that JPEG2000 was intended to replace standard JPG, but I guess that idea fissiled out.

I was using JPEG2000 to save hard drive space. But I did not know that it might be exclusive to Photoshop. There is a photoshop plug-in that says "JPEG2000" from the CS5 plug-in folder I saved before I removed the CS5 program from my computer. I tried to install it in Affinity Photo but for some reason Affinity Photo will not recognize it. I recall that Affinity Photo was supposed to be able to read Photoshop plug-ins. I wonder why it won't work with the JPEG2000 plug-in.

Glad you figured it out. I am still in the process of downloading the program PhotoLine. My internet is kind of slow and it says it will take another 10 minutes to download the zip file. Anyway, the reason I save in LAB color is because that color mode mimics the color perceived by the human eye and it makes more accurate color prints. I have tried to print in RGB but the colors are never what I see on the screen. When I print in LAB mode the colors are almost identical to what I see on the screen. The only difference is the prints in LAB are not quite as light as I see them on the screen, but for me color accuracy is more important. As soon as I complete the download I will give it a try.

I never get into subscription plans. That is why I went from CS5 to Affinity Photo. When CS5 quit working on my newer Mac the Adobe techs told me that Creative Cloud was the only photoshop related program that would work on my newer Mac. I live in a remote area and my internet connection is rather slow. I don't like programs that have to connect to the internet in order to work properly. I may try that PhotoLine that someone else mentioned. PhotoLine has a free 30 day trial. If it works I might be able to do the conversions before the time expires. But if it does not work then rescanning the original photo prints will be the only way. I will just have to save the rescans as TIF next time. If PhotoLine works or not I will post it here so you all know whether or not that program will work with the types of JPFs I have.

I forgot to mention that I did do the JPEG2000 lossless conversion you suggested, but it only produced an image of 900 pixels and 8 bit RGB. The original image saved with PSCS5 was over 2000 pixels in size and in LAB 16 bit. A low resolution 8 bit RGB version is useless to me, so I will have to try another program. If another program cannot work then I will have to rescan all of these old family photos, which could take weeks since I have several hundred of them. I originally stored them in JPEG2000 to preserve the high quality of a TIF but with only a third of the size. I will have to remember not to use JPEG2000 again since the programs capable of using it is apparently limited.

I did manage to install the 1.7.3 update. I had to sign out and sign back in to get it. As far as using the Preview App I have already done that before and got the same results. It will only convert the low resolution version and in only 8 bit RGB. That is not the original color mode or size that was saved with PSCS5. Either the file is corrupted or Photoshop put in a code preventing other photo editing programs from opening the original data in the file. I will have to try another program I guess.

I managed to get the 1.7.3 update, but it still will not open .jpf or any of the other variations. Here is a screenshot of the error I get. I can only conclude that either the file is corrupted or Photoshop put some kind of code in it preventing it from being opened by other photo editing programs.

The original file was .jpf but I did create copies and renamed them to .JPF, .jp2, and .j2K and not one of them would open. I originally bought Affinity Photo from the Apple App Store back in 2017. Since then the App Store has updated the Affinity Photo program several times and the last update I got was 1.7.2 I just checked the App Store and there are no further updates for my version of Affinity Photo. So 1.7.2 is as high as mine will go. I don't have the other Affinity Apps, just don't need they others. If you want to try and convert one of my files here is the one I have been experimenting with. It is the original .jpf version saved by Photoshop CS5. Chris Birthday009.jpf

I just tried the program and it did not work. When I opened it with the program colors were wrong and it only saved it in RGB 8 bit, not the 16 bit LAB that Photoshop originally saved it in. Maybe I am doing something wrong, or the file has a code in it from Photoshop that prevents other programs from converting it. If you want to try I am including a copy of the file I have tried to open. Chris Birthday009.jpf

All of my JPEG2000 files were created with Photoshop CS5. The extension for all of my files is .JPF not .jp2 or .j2K. I currently use Affinity Photo version 1.7.2 I checked to see if it would update to 1.7.3 but it won't. That might be due to my running it on Mac High Sierra. I did try to rename one of the files to both .jp2 and a copy of it to .j2K but Affinity Photo 1.7.2 still will not open it. I still get the error that it is not a supported file type. If you're able to open .j2K and .jp2 it could be due to your using version 1.7.3 I don't know for certain, but since mine will not update to 1.7.3 it is possible that version 1.7.3 is not compatible with High Sierra OS. I know that some programs will not update if they detect an incomparable operating system. That was the reason I got Affinity Photo was because when I upgraded my Mac from Lion to High Sierra Photoshop CS5 quite working.

Thanks for the suggestion. I may try PhotoLine as a last resort. But since I use Affinity as my primary photo editing program I would like to use Affinity for the conversion.
