1440x1080 pics skewed

I am taking pics during filming but they look like perspective is off. Anyone else notice this? It appears objects look too thin. Should I set pic size differently?

You will need to tell your photo program that the image is at the right aspect ratio. Your pictures are pixel-for-pixel correct, but probably being displayed in square pixels!

If the images look like a Spaghetti Western (squished), it's because your viewing application is using the wrong Pixel Aspect Ratio (which needs to be 1:1.333).

To put some numbers on the answers above - you probably need to stretch your 1440x1080 pixel image out WIDER to 1920x1080 pixels, in a still image processing app.

Batch stretch in photoshop

Martin - that was it. The frame grab needs stretching. My Dell Image Expert program can't stretch and I am Photoshop stupid. Anyone have simple way to batch frame grabs and stretch? - Steve

A good alternative is Paint Shop Pro from Corel. Download a trial version and if you like it, the cost is only $120 or so compared to the expensive of PhotoShop. You can set up a batch script in PSP to change the aspect ratio of a group of images; its help files are very extensive so it should be relatively easy to learn how to do.

Psp

You'll find PSP is good - but after a while it starts to slow down your pc if you allow it to index too much.

It was far far better when the product was owned by it's creators - JASC Software. COREL have done what they do with most things and turned it top heavy with lots of silly peripheral stuff that really isn't needed and is equally heavy.

Overall - better value for money than Photoshop.
