I posted previously because I was having issues with TIFF files of negatives that I scanned in. The Process Multiple Files adding a watermark doesn't work in PSE as expected on the files. After some experimentation I found that if I scan the negatives at 8-bit grayscale instead of 16-bit grayscale PSE works as expected.
A couple of questions based on this observation:
1. Will the difference of 16 vs 8 bit during the scan make a big difference down the road when these are printed 8x10 or 11x14?
2. Is there a way to convert in batch from 16 bit to 8 bit grayscale?
3. Any clues on why PSE acts differently based on this? BTW the 16 bit are 13MB in size and the 8 bit are MB in size.
Thanks for any help that you can provide.

After some experimentation I found that if I scan the negatives at 8-bit grayscale instead of 16-bit grayscale PSE works as expected. I never thought of that. Kudos to you! You hit the nail on the head! Elements offers limited support for 16-bit files. One of the tools which won't work with 16-bit files is the Type tool. That's why it didn't work when you tried to type a watermark.

Wow... Seems like PSE would give you some sort of error message during the process. I turned on the error log during the process and there was nothing listed except "successful".
So now a couple of other questions:
- Are you saying that Photoshop should process the watermark in Process Multiple Files mode as it should? If I subscribe to the Cloud version of Photoshop could I add the watermark in this mode?
- Is there a way in PSE to convert my 16-bit files to 8-bit in batch mode?
Thanks

Thanks Previous discussion: forums.adobe.com/thread/2315383- I have not yet tried the watermark process in Photoshop CC... I believe that should work. - I must admit I don't know a way to batch convert 16-bits tiffs into 8-bits tiffs in Elements. It seems that the two solutions: 'process multiple files' in the Editor and 'Export as new file' in the Organizer don't let you change the bit depth. I suppose a script like those in Elements+ might to the trick... Maybe Andrei Doubrovski could give a suggestion, I have not found such a script in Elements+. I can use the 'Open in ACR' command of the editor to open a batch of 16-bits tiffs in ACR, then set to open in 8-bits in the editor. I select all and click 'open in the editor'. That opens copies of all files in 8-bits tiff in the editor. The problem is that I have to save each file individually, the 'Save All' script in Elements+ could save all those edited versions in a predefined folder. What you can do now for free is to use Faststone Photo Resizer. The advanced options of the batch conversion let you change bit-depth. |

I am going along with Michel here . . .
- I have not tried watermarking in Photoshop CC either. But I believe it should work. - I have not found a way to use batch-processing to convert 16-bit TIFF files into 8-bit ones in Elements. - The only thing I can think of is to use the ACR Converter as described by Michel. - As to Elements+, . . . it might work. I will send a PM to Andrei bringing this thread to his attention.

jhousemb, If you use Elements+, you can batch-convert your images as follows: 1) Download and unzip this script: elementsplus.net/scripts/Convert-To-8-Bit.zip2) Put the unzipped "Convert-To-8-Bit.JSX" file into your "...\Scripts\Batch Optimized\" folder. For example, for "Elements+ for PSE 15, Windows" the path must be: C:\Elements+\15.0\Scripts\Batch Optimized\ 3) Open Elements+ "Scripts" dialog (File > Automation Tools > e+Scripts)  4) Run "Batch" script  5) In the "Source" area of the "Batch" dialog, select "Folder" option, click "Browse, and choose the folder with your 16-Bit TIFs  6) In "Scripts to Run" area, choose "Convert-To-8-Bit" script  7) In the "Destination" area, select "Save to Folder" option, and choose your target folder.  8) Click "Run" to start the batch-conversion. Hope this helps. |

Wow... such great information. Thanks.
I have a ignorant question... what is Elements + ?

Wow... such great information. Thanks. I have a ignorant question... what is Elements + ? It's a set of additional tools recovered from the full Photoshop. It is developped by Andrei Doubrovski and sold at a bargain price. elementsplus.net/Andrei is always helpful when we need more technical information. |

The price is right and Andrei provides five-star help. |
