Hi folks,

I have loads of photos that I want to put on a website, but I have been told the have to be converted to 72dpi.

Does anyone know of or use any software that you can convert batches of photos rather than doing the one by one on photoshop, free waould be best but I am willing to pay a small amount.

Cheers

Spike

I use Bibble when converting from RAW and Paint Shop for resizing. I'd be very surprised if you couldn't batch run a script in photoshop that would do what you want.

Hi,

I was told how tpo reduce the dpi when I export from Photoshop Lightroom (assume you have the same fucntionality in PS).

When you go to export you can select the quality and also the dpi settings to use.

Hope that hels

If you do have Photoshop already then follow these steps:
This is how it works in the CS4 version of Photoshop, and from memory the CS3 and previous versions. I am not sure about Photooshop Elements or some of the more parred down versions.

Put all the photos you want to convert into one folder and name it.
Open Photoshop
Go to the "file" pull down menu at the top
Scroll down and open "scripts"
Then open "image pprocessor"
This will open a dialogue window
choose the folder you put all your photos in
and choose the setting you want as far as quality (dpi) and size etc.
Press the "RUN" button and presto ....done.

There is other ways to do it in Photoshop with the batch processor but this one is pretty simple and straight forward.
should be able to do it in under a minute.

cheers, here Bach at ya!

The 'dpi' setting you refer to (which more correctly is a ppi setting) has no effect on displays. It's almost always ignored by 99% of software and was historically used in DTP software to cater for the fact that Mac displays were at 96ppi and PC displays were at 72ppi to ensure that images placed within the flow of the page were displayed correctly (i.e. representative of the image's size in relation to the page).

The only thing that affects image size on a display are the pixel dimensions.

So, if you upload at 300ppi, 72ppi, or 1ppi the image will look exactly the same and have the same file size. In fact in Photoshop the only time you can set the ppi is when you resize the image at which point it gives you the equivalent inches size should you decide to print it out at that ppi.

PPI is relevant only to printing.

For anyone using CS5 i found a batch resizing option which worked quite well under File_Automate_Batch.... it was good but could be much better, there are much easier programs out there for free.
