A Macro for the Camera?

[chandelirious]

Alrighty There People!

First post here, so be nice :)

I was just wondering: Are there any macros available for the camera on the N95? - Or an advanced camera software package for it?

What I want to be able to do is pop the camera on a tripod, then set a macro away that will set the exposure level to 2.0, take picture, then set the exposure level to 1.5, take a picture, right through to -2.00 - all without me having to touch the camera after setting the program away.

Is this possible?

Cheers in advance...

Welcome to the forums.!

Have a search of the forums, as there has been similar asked before, and there are certain lens attachments available for the N95, however, telescope type, there is also mention of a Fisheye type lens.

ok Micky what I believe he means is modify the settings without touching the phone, not a macro lense but a macro like a script to run.

Chand what you want to do is buy yourself a BT keyboard to do this.
I believe this is the effect you are going for

If you don't want to try your luck with the keyboard you may want to look into some python programming

I have heard of HDRI but never tried it - sounds interesting and could be fun with the N95.

You can save the exposure , macro etc by using the camera pp. But dont know how you can o it without touching the camera unless you use a timer.

erazer, you need a BT keyboard. In order to do the HDR photos the camera has to remain completely still therefor negating the possibility of setting the exposure on the phone itself. With a quick python script this may be easy to do but I haven't looked into pyhon at all yet.

I've mentioned this in previous threads. There is a Python interface to the camera that could do what you (and I) want, but Nokia have kept the exposure compensation functionality as an internal API, so unfortunately it can't be used :(

I think that the ISO feature might also be an internal API (or at least not available from Python) - the exposure documentation offers:

exposure is the exposure adjustment of the device. Exposure is a combination of lens aperture and shutter speed used in taking a photograph. The default value is 'auto'. The following exposure modes are supported:
'auto'
Sets exposure automatically. Default value, always supported
'night'
Night-time setting for long exposures
'backlight'
Backlight setting for bright backgrounds
'center'
Centered mode for ignoring surroundings

Not much use for HDR :(


EDIT!:

Ooh - Nokia have recently released an addon which gives Python access to ISO and exposure compensation functionality! See the example here

That's exactly they type of thing I was after.

I'd heard about the Bluetooth keyboard, but wanted to know if there was another way first.

Now I just need to work out how to use it....

Thanks for all the responses!

Python has also been used to generate HDR pictures here. PIL isn't available for PyS60, but NCVlib is, which may be capable of the same thing (I'm not sure if there would be enough memory on the phone though, so it might need some clever swapping to storage).

Thanks for that.

To be honest, I'm not bothered about creating the HDR image, I can do that - it's getting the four or five images with the different exposure settings that I really need - without using a Bluetooth keyboard.

So, basically, all I need is the script that will allow me to activate the camera and take the images at the different exposures. The rest I can do myself.

But, since python (and all programming!) is a foreign language to me... I can't do it myself...
