hi, cheers for the hard work, when should i be expecting this amazing app?

Re: Retro camera app - Need image processing advice
 

It won't be long. Maybe tonight if I get time. I'm still just finishing some of the untidy bits and making it faster. It now takes just under a minute for a full resolution photo to process which I think is acceptable for now.

I'm currently trying to package it up to submit to extras-devel but, not having done it before, I'm trying to be careful to make sure I get it right. I also haven't got permission to upload to extras-devel yet. I've requested permission a couple of times but as yet received no response.

Failing that, I'll put a link on the project's garage site when it's ready.

Good news, can't wait to try it out =)

Re: Retro camera app - Need image processing advice
 

Everybody here should say a big thank to you. It was one of the app I'd like to see on N900, as I wrote months ago.
I tryed to start creating it myself, but my devel capabilities are cheap.
Thanks.

This looks really nice. I've been experimenting with rolling my own filters using imagemagick, although I ended up piping my photos to a server I run via pixelpipe and dropbox, running the filters remotely and pushing the photos back to the phone, due to the amount of processing power some operations require.

A few tips for effects:

You can make curve presets in any app with curves and apply those curves to a grayscale gradient to create a look-up table that is easily applied to images.

For a basic technicolor two-strip look, simply copy the green channel of a photo to the blue channel and do some curve adjustments.

One effect I've found quite nice is the bleach-pass look: take a grayscale version of your photo with increased contrast and composite with the original (or, for better results. a colour-corrected version of the original) with the soft-light or hard-light blending mode.

Here's the result of one filter I cooked up, combining a technicolor-esque colour scheme with the bleach pass look and a grain+vignette layer on top:

Re: Retro camera app - Need image processing advice
 

That's really cool - looking forward to testing it.
Thanks a lot for creating this.

awesome job buddy. Thank you.

Re: Retro camera app - Need image processing advice
 

Maybe you can merge your project with BlessN900?

Re: Retro camera app - Need image processing advice
 

Thanks for the kind words everyone. Sorry to dissapoint but I didn't manage to get a package ready for download tonight. I didn't get much time to work on it this evening.

I have successfully made a package but it's got a couple of small problems which I need to fix. I also want to do a bit of testing before letting people loose on it to make sure it doesn't do anything bad.

@rebuilder - that was a very useful first post! Some of my effects are similar to what you describe and I am already using a level lookup table (in fact multiple tables) but I'm quite keen to try some of your other tips. Maybe in the next version...
