Hi everyone this is my first post.

I wonder if anybody could help.
Im starting to make wallpapers for mobile phones and i want to make them so there "VERY" High Definition but im not sure how i can do this, i use photoshop for all my wallpaper i make.

Hope you can help.
Cheers...

Just wondering, why would you want to make wallpapers for mobile phones HD? They have very limited disk space to begin with. Anyways, you can still use Photoshop to make them. No different from any wallpapers.

Its something ive always done on mobile forums for members.
But now i want the quality much much better for them i know they will be a much bigger file so it will only be able to go on certain phones with big memory...

Anyway how could i do this with photoshop?

The quality of just about anything is determined by size. More pixels = better quality.

Im no expert with phones, but most will not display huge images nor the quality you have in mind. Or if they do, the phone's software will probably resize them for you.

So to answer your question, just make LARGER wallpapers. Then resize them properly to fit the phone. What you'll need to do is carefully resize them, to retain as much quality as you can. Resize in small amounts, sharpen etc.

Until someone makes big/better screens, thats pretty much all you can do.

So if i make an image 240 x 320 is there no way i can add alot more pixels to make the quality better?
Sorry im not 100% sure...

You can't add pixels to an image, unless you make it bigger. If 240px x 320px is the size you need, your pretty much stuck with it.

What you can do though, is when creating your wallpaper, create the image at like 480 x 640 (200%). Then use higher quality graphics/photos and slowly resize the final image back down to 240 x 320. Basically your faking a quality look by carefully throwing out pixels each time you resize, other than all at once. The usual rule is to resize by 10% each time.

Also just so you understand how pixels work, take HD video as an example. A common size would be 1280 x 720. That's HUGE compared to the screen on your phone.
