It could be interesting to use ellipse region or area selected with finger (i don't know if it's complicate

I thought about it but I don't think we can define ellipse out of the screen so there will be part not blurred and some part would overlap each other.

Also for the finger painting I think it's far more complexe to achieve something like what is done in Cinemagraph app and would have also required a custom effect in order to define blur on the user defined areas.

With the beta version, you have a filter where you blend (normal mode) two pictures and where you give the alpha channel in another picture. I don't know if an equivalent system exist with the new version.

I thniks your algo is similar to blend a picture and its blurred version with a alpha gradient. (but i could have wrong)

Hamishwillee - I love this effect!

Hi MaMi

This is a lovely effect. Like Yan, my technical expert suggested gradients would be better than the rectangle approach.

As an article I felt great until it got to the end, and just .... ended. You might want to have a small number of screenshots at the end showing the different effects of changing your slider positions.

Thanks so much for contributing this. If you have time to update with the gradient approach that would be great.

regards

MaMi - Thank you for your feedback!

I'm not sure to understand what you mean by using gradients instead of rectangle, as I created a gradient using rows of rectangles.

At first I tried to create a custom effect that would have allowd me to blur each pixel independantly. But I ran into two major issues, performances were pretty bad, and I was not able to use existing color boost effect. So in the end I used existing blur effect, using multiple rows in order to create a gradient.

Regarding screenshots I'll definitely add some ASAP.

Best regards

Okay while I was applying the effect to new photos I realised that there was indeed an issue with my gradient. As the Minimum blur value was too high, the edges of the blurred areas were too visible. In order to fix this I reduced the MIN blur value from 10 to 3 and edited the article consequently. Now the gradient looks better (IMO).

Side question, is it possible to replace the source code zip or should I upload a new one and edit the article?

I will check with expert on gradients.

Yes you can, and yes you should upload a new one. There is a link for that on this page: File:TiltShift project sample.zip

I have just subedited this for English and Wiki Style. Please check out the changes (you can see them in the history tab) and confirm that you're happy with what I've done, and that I haven't broken anything. In essence this includes marking up inline code objects with Template:Icode to make them monotype, fixing the code block syntax markup. I've also used "gallery" for multiple images, and "frame" for the single images so that your image comments are visible. Note that I've added "none" there too to force the images to be left aligned. If you need smaller images you can use "thumb" - all about this in Help:Files & Images. There is general guidance on wiki standards here: Help:Wiki Article Review Checklist

In terms of content changes the main impact is in the introduction. Reading the definitions miniature faking is a better description generally than "tilt shift" for readers.

Anyway, this is really nice. Thank you.

Hello,

The changes are fine for me.

I've also uploaded new version of the project.

Cheers
