Re: [WIP] cameraplus for Sailfish OS
 

I have just read this and made some maths and your supposition is exactly right:

8Mpix means: 8 * 1024 * 1024 pix = 8.388.608 pix
It is a rectangle of 4 x 3, that means that the width (long side) is:
sqrt(8388608/4/3)*4 = 3344,37 pix

If we are cutting the photo to get a 16:9 one, we maintain the width but not the height, so in 16:9 the width is the same. Then the height (which have a 9:16 proportion to the width) is:
3344,37 * 9/16 = 1881,21

So the pix we have in a cropped 16:9 image are:
3344,37 * 1881,21 = 6.291.462

And 6 Mpix are: 6 * 1024 * 1024 = 6.291.456 pix

So, that's correct, 16:9 photos is got cropping them from 4:3.

(If you use more decimals you will get the exact same number).

PS: I am changing just now the camera to 4:3. If I would want to crop the photo, I will do it by myself.

Take care because if you crop it manually, you end up re-encoding the jpeg image which might lead to some artifacts.

Re: [WIP] cameraplus for Sailfish OS
 

I doubt that but thank you. If am I sure I want something in 16:9 I will use it, but if not, I prefer to get more image and let it in 4:3.

Re: [WIP] cameraplus for Sailfish OS
 

I'd like to see more choices for crop. Sometimes I want the full resolution and crop later, reencodning isn't really an issue since I'll be adjusting contrast and colours anyway.

But mostly I prefer to get a finished picture in the camera. Especially if I'm using the phone. Sensor and lens isn't good enough for good pictures anyway and no raw format limits the possiblity for post work.

So, I wish for 1:1, 3:2 and 5:4.

Re: [WIP] cameraplus for Sailfish OS
 

I'd like to have that too but I am limited by what the driver/camera HW itself can do.

In Sailfish it's an issue because I get jpeg images and I can't manually decode and crop because the quality will suffer.

Re: [WIP] cameraplus for Sailfish OS
 

I see. Better leave it as it is until that can be solved.

Could be usefull with a overlay, but I'm not sure it's worth the bother.

Re: [WIP] cameraplus for Sailfish OS
 

Is it possible to have a video mode that makes the file better suited for sending via mail or messenger services like Whatsapp? Even the lowest resolution available currently makes a 10 seconds video pretty big. I can record 30 second clips on my android phone that looks pretty ok and are smaller in size than a 10 second video with the lowest possible resolution in cameraplus.

Small bug: I have to click the record button twice in video mode to make it start recording.

Re: [WIP] cameraplus for Sailfish OS
 

It can be possible with some black border on top of the viewfinder and lossless cropping of the jpeg image (If everything is calculated correctly) but then we might have issues while zooming.

An alternative approach would be to have an image editing tool with lossless cropping functionality. I don't know if I will ever get to making that tool or not but I can help anyone trying to make it.

Re: [WIP] cameraplus for Sailfish OS
 

At the moment I am using the same bitrate for all videos. I need to fix that which should lead to decreased size for the lower resolutions.

I have an issue about that here: https://gitorious.org/projects/cameraplus/issues/33

Sometimes it happens even in image mode ;)

0.0.25 is out

- New icon by mcbook
- Do not prevent the flick to settings or post capture if the drag starts from the focus reticle
- Changing image resolution aspect ratio should re-position focus reticle correctly
- Reset touch focus when we switch between image and timer modes
- Touch focus now takes into account inverted landscape orientation

enjoy :)
