TIFF to JPEG with Automator
I am doing a large scanning project and using Automator to convert TIFF to JPG. I find that it generally works well, but inevitably, many of the resulting JPEGs have horizontal bars of static. Sometimes I can "Rework" the bad files back through Automator and it will correct the problem. Other times, the horizontal bars of static persist, and I have to manually go into PREVIEW app and convert from Tiff to Jpeg there. I notice that when I do it this way, I get options for quality level of the conversion. Default is 80% and I can bump it up to 100% and a larger file size.
I will have batches of from 5 to 100 slides that I process in this way. The average batch size is about 25.
My initial Automator workflow was
1) Get Selected Finder Items
2) Copy Finder Items (to a new folder, so I don't wipe out the TIFF files)
3) Change Type of Images (to type: JPEG)
This workflow will copy all the TIFFs to a new folder, then it opens them ALL in Preview, and converts them all rapid fire to JPEG. I thought this might be a problem so I put a loop in the workflow. So now my workflow looks like this:
1) Get Selected Finder Items
2) Dispense Items Incrementally
3) Copy Finder Items (to a new folder, so I don't wipe out the TIFF files)
3) Change Type of Images (to type: JPEG)
4) Loop
This new workflow gets a higher percentage done correctly, but there are still several images that have the horizontal bars, requiring manual rework.
Does anyone have any suggestions?
For the record, my entire workflow is the following. I know I could automate more of it, but cannot when I have to do the manual rework.
1) scan slides on Epson scanner
2) Use A Better Finder Rename to rename files.
3) Run Automator workflow to convert TIFF to JPEG
4) Run A Better Finder Attributes to change file dates of jpegs
5) Import into iPhoto, name the Events, set Faces, set Places, do Edits including crop, color correction, etc.
Thanks for any ideas.
