Creating 8 bit Tif files / elements?

[Tobyh]

Hi all,

I seem to be a bit stuck on this. How do i see / find out if the tiffs I create in Photoshop Elements (8) are 8 bit or not? Also - how do I ensure that it's 300 ppi/dpi? A straight conversion from a RAW is showing as 240ppi for me - is it just a case of Image>Resize and then changing PPI to 300 there>? basically ..upscaling it?

Any help appreciated!

Thanks

Hi Toby,

When you have the image open in Elements go to the 'Image' menu option and then to 'mode' if 8 Bits/Channel is greyed out you have an 8-bit image if it is clickable (if that's a word) then you are in 16 bit if you click it will convert it, I normally make this the last thing I do if I need to convert it.

To change the resolution you can do it without upscaling. I normally open the image size dialogue set the required resolution and then put the pixel dimensions above back to normal.

Hope this helps.

Cheers,

Is there any particular reason for needing 300 ppi?

Image size and ppi are all relative to each other and increasing or decreasing one directly affects the other. Unless you add or subtract the actual number of pixels.

For most applications there isn't any noticeable difference between 200 and 300 ppi. But, obviously, there isn't any good reason to 'throw away' good pixels from your original image.

Geoff,

My reason for asking is because it's a requirement for submissions to the British Wildlife Photography Awards should you be successful in getting through the initial round. For once I'm being optomistic
