.psd versus .tiff

[AmberLV]

I'm not technologically savvy. What is the difference really? Any difference in quality?

[mmy2vce]

.psd is (I think only for Adobe).

.tiff can be used the same way as .psd and can be used to save layers or you can discard your layers and use it the same way as jpeg without losing quality due to compression. .tiff can be used in DIP when .psd can't

.tiff is best used on your photo's instead of jpeg so your photo quality never deteriorates. clear as mud?

Well Jen Caputo just posted in another thread that .tiff files are significantly smaller in size than .psd files, so I might just switch!!

That is not true. Both .tiff and .psd open up as a flattened image in DIP.

PSD files can be opened (and saved) in PSP and Photoshop. When you open a PSD in PSP, you do lose the layer styles from PS.

Layered TIFFs open as flattened images in PSP.

I use PSCS2 and the tiff file being smaller is true for me...and they remain separate layers for me as well.

yup, just turn on LZW compression when you save your tiffs, you will be amazed at the hard drive space you save!

I guess I just might switch to .tiff. What is LZW Compression? I'm working if PSE 5.0, if that matters.

I am extremely curious about this as well. I use PSE4. Jen...yours are one of the few that are smaller than the PSD's, so I need to know how to do this!! I have a large hard drive, but I'd still like to save space!!!

Thanks!!!!

LZW compression is a lossless compression (meaning no data is lost). It's really efficient too!

Anyway, to save your files so that they are the very smallest but you won't lose a bit of data use these settings when you save your tiffs:
Image Compression = LZW
Pixel Order - Interleaved
Layer Compression - ZIP

Those are PS CS2 options, I don't know what they are in PSE but hopefully they are similar!

For comparison, in my last sketch collection (double pagers), sketch 3 is 2.16MB as a tiff, and 11.3 MB as a PSD.

If you use any version of PS - save as a tiff!!!!
