Resizing images in a batch
-
Right, I have finished editing a set of interior shots and all I want to do is wrap up and shut down the computer, all images are already edited and all are cropped to a 4:3 ratio, but then comes the mind numbing bit. I have to re-size all the images.
I re-size to two sizes:
12 x 9cm at 300dpi and image quality 11, these images are called “brochure – name.jpg”
668 x 501 pixels 72dpi and image quality 9, these images are called “web – name.jpg”Okay it does not take that long but it is after a day of shooting and processing and it seems to me that I should be able to automate this, in a way that I can put in all the above details including image quality and dpi.
Does anyone know how to do this? and care to explain in the simplest way possible. I use PS CS4 and a mac book if this helps anyone.
Thanks
Brian
Brian,
Not sure if your using Canon but if you are the DPP software that comes with the camera has a batch processing function that allows you to rename, resize and save to a number of formats in one go.
I think Adobe bridge might have the same function and its part of PS CS4 but I’m not sure, don’t have it on the PC at work.
Hope that helps…Jay.
take a look at FastStone photo resizer it may do what what you want. I have used it and it seems good and its fast. It will defo change the dpi and resize in pixcels not sure how well it will cope with the length in cm

The below is for elements but i would imagine terminology is similar in photoshop:
1.Put all the photos to be processed into a single folder.
2. Create two folders to save your processed for upload – one for brochure files and one for web
3. Start Photoshop Elements in Full Edit mode by clicking Edit in the Welcome Screen. Or, if the Organizer is
already open, click the Editor button located near the top right corner of the Organizer window, and then
choose Full Edit from the menu.
4. If the Editor is already open from an earlier exercise, switch to Full Edit mode if necessary, by clicking the Full tab in the Edit pane of the Task panel.
5. Choose File > Process Multiple Files.
6. In the Process Multiple Files dialog box, do the following:
• Choose Folder from the Process Files From menu.
• Under Source, click Browse. Find your folder of pictures. Click OK to close the Browse for Folder dialog
box.
• Under Destination, browse for your destination folder.
7. If you wish, you can adjust the filename, but again it is better to do this to the original file.
8. Under Quick Fix on the right side of the dialog box, select “Sharpen”. You can select the other options if
you wish but it would better to have previously fixed any colour problems with the original files.
9. Under Image Size, tick “Resize Images”. Change the resolution to XXdpi. Enter XXX as the maximum width etc
10. Under “File Types” select the quality you require
11. Click “OK” to process the files.I don’t know off hand, but you should be able to create an ACTION.
I would check it out on some of the PS sites.I also recommend FastStone for speed and simplicity.
Ignore the “72DPI” – it’s meaningless for for web/screen display (contrary to common opinion).
It’s a doddle in Photoshop CS4. I do it all the time when doing repetitive commands.
You create an action. Than you record the action. In my case for example when finished working on a whole set of images, an action I use is open image, unsharp mask, save, change profile to sRGB, re size to 2000ppi image, change mode to 8bit, unsharp mask, save as jpg (I have a special folder for the 2000ppi images) re size to 750ppi, unsharp mask, save as (I have a special folder for the 750ppi images) and finally close.Once you have gone though all the commands that you will wanted repeated for the other images, you stop recording. The action can than be run anytime within CS4 or else you can batch process the images either from a folder or from opened images within CS4.
It’s one of the most useful tools. Recently I had a job where the client wanted 95 images. That set of commands would take in and around 5 minutes to do. I was able to let CS4 run in the background and it saved me a days work.
Not sure about the renaming as an action. I never tried it myself. I use the automater tool. I see you use mac. It’s a really good freebie that is a bit similar to the action command. For example you can rename multiple files. So you specify the bit of text before each old image title and it does the rest.
IrfanView freeware should do it for you as well. It as a very nice batch conversion feature with “advanced” options.
