Have a "rule of the thirds" overlay to assist with composition of photos.

Need to be able to make a EV adjustment on the camera to get the exposure correct.
Trying shooting a good sunset photo. Impossible.

We can tap on the screen to take a picture, allow us to tap on the screen to start record video too.

The picture created by the camera of wp7.5 is too bad ,I think you should change your algorithm of the camera!!!!

Make video call available please.

Annoying that we have to switch it to HD every time.

The lead time between clicking the button and taking/saving the picture is way too high in Samsung Focus S that comes with Mango OS.

Basic Technology is MISSIMG. It is 100% falut.
How can EAT with your hand WITHOUT zoom in towards your Moth.

allow the camera to save HD or HDR file formats which allow greater flexibility for correction on, or off the camera at a later date.

There is no way to edit videos taken on my WP8. Even if I pull the video onto my PC, there is no app to do this. The only way to edit it is if I convert it to a different format. There should either be an app on my windows phone that will allow me to edit the video, or Movie Maker should be enhanced to allow the editing of the video formats taken from my phone. This is a huge deficiency in WP8!!

When using the "Vision" search to read QR codes, it would be useful to support the smsto protocol. It's currently handled just as text.

If we need this support, we still have to install a third party QR code reader!

Should be able to delete pictures on the camera from skydive roll, just as you can delete them from camera roll.

It would be nice to take a picture by just pointing at the object and say something like "Click" to take the picture. Sometimes when you hold the phone its not so easy to find and press the camera button. Whould be a simple and cool feature.

Use hardware buttons for camera zoom like Nokia N8

When looking through old photos I often wonder "when was that taken?". I touch to see all the options like share, etc... But I don't see an option that would show all the metadata. Where was it taken? (link to Bing maps). When was it taken??

Add an option to store/save photos from camera in RAW format (as there are phones with good cameras, Lumia 920 for example)

On time of recording a video,sometimes we need to zoom in or out.Let us do it!!

Can you develop camera disable software for windows phone as similar exist for Android phones which allows user to disable camera in restricted areas.
