I have a load of photos from my holidays and a lot of them need to be brightened up to make them look better. How can I brighten them all up at once? Is it possible in photoshop? Please tell me what I need and how to do it. Thanks.

    I don't know Photoshop...but if photoshop or whatever graphics package you are using has a command to brightened photos (I never saw one that did not).

    Thumbs Plus does have this option and the software is not expensive.
    There may still be a 30 day trial.

    Select the files you want to brighten
    Click on Image, then Batch Process and follow the prompts

    There are several Photoshop adjustments you can use to do this. Look under the Image|Adjust menu. The Levels, Curves, and Brightness/Contrast adjustments are all possibilities.

    To do this for a large number of images at once, you can record a Photoshop macro called an "Action" which applies the desired
    adjustment, and then use the Automate Batch option from the File menu to run that action on all the files in a folder.
    You'll want to make backup copies of all your images before you start experimenting.

    To add to what Bill said...

    Things to take into acount are that depending on your photos, the process and extent of brightness may vary from picture to picture. If you have say 45 pics that are all just a little dark, then you could record an "action" in photoshop while you change say, the levels, and then save and close to a new folder.

    Remember, Automating photoshop functions can be very powerfull and timesaving, but carefull attention need to be used when selecting the technique used to acomplish said goal. Adjusting lighting is usualy simple, but pictures tend to vary ever so slightly so hand doing them may be a good option. Also I am sure you want to maintain quality, so be carefull to resave in good quality.

    - To get started Open one of the pictures.

    - If your "Actions" pallet isnt in view, go to the top menu and select Window/Actions (Alt-F9 in windows)

    - Press the RECORD button (red circular button) on the bottom of the pallet.

    - Name it somthing.. hit "record action" (everything "action" you do will be recorded from here on out)
    This is reflected if you watch your actions pallet...

    - Select your image file. Hit Ctrl-L (or image/adjustments/levels )

    - When you have the look you want accept the changes, then save the image. Usualy its best to start a new folder and save the new image there.

    - now close and dont save changes...

    - Hit the stop button on your action recorder....

    Now you can repeat this on a whole folder of images (Pluss some advanced naming options) by going to file/atoumate/batch

    It is possible to brighten all at once with a batch command or Avtion, in Photoshop. However, the task actually is a more delicate that this would allow. To brighten you almost certainly would need to increase 'brightness and Contast' and maybe some channels. As to how much depends on the image and that will vary from one to the next, so the batch idea is not a good one.

    >As to how much depends on the image and that will vary from one to the next, so the batch idea is not a good one.

    Not necessarily. Sometimes, batch processing is the best way to go.

    Certainly if all you care about is obtaining the best possible image quality, you'd want to fine-tune the adjustments to each image.
    But often this isn't necessary, and sometimes it's not possible. When working with hundreds or thousands of images, manually adjusting each one may simply be out of the question, due to time or budget constraints.

    Using batch processing can give quite reasonable results, especially if the photos generally have the same problem (all are too dark, for example.)

    Since you have a copy of the original unadjusted pictures, you can run a batch process to apply an adjustment that is "good enough" for the majority of images, and then look at the results, and go back and rework any images that didn't turn out well.

    Hi torvalds,

    You can also do a batch conversion (if you decide to go the batch route) with the freeware Irfanview:

    Click on File>Batch conversion and check "used advanced options". Click on "Set Advanced Options" there and set your brightness and/or contrast levels. You will see on the left how to add your files. Set an output directory, then click "start".
