New Patreon page to support the development of FotoSketcher

Hi all,

I've just launched a Patreon page to allow people to financially support the development of FotoSketcher:

Of course this is entirely optional. FotoSketcher remains 100% free, even for commercial use.

As I recently shelled out over €1000 for my development setup, I thought I might try out Patreon as a revenue source.

Some users have also made donations via PayPal ( and I take the opportunity of this post to say a big thank you! Many a cup of coffee was bought thanks to these donations :)

All the very best,

FotoSketcher for Android - new test app available

Hi all,

If you like to be on the bleeding edge and have an Android device (phone or tablet), here is a new .apk file for you to play with (you will need to allow your Android device to allow untrusted applications to be installed, so it's for advanced users only) : FotoSketcher.apk

You can take photos, open images from your picture gallery, apply different parameters and save the resulting "painting". To open the parameters menu (and run the effect), tap on the menu icon in the top right corner of the screen.

The available effect is very much a work in progress and is far from being finalised.

BTW, you might still encounter "application not responding" error messages, but hopefully they should be rare.

Have fun!

FotoSketcher for Android - progress report *** update: Android test app available ***

Hi all,

As promised, here is a quick update on the FotoSketcher for Android proof of concept. I have started experimenting with direct pixel access (which is needed for my algorithms) and as a testbed I have ported part of the Painting 9 algorithm.

Here is a screenshot of the work in progress (obviously the interface will be improved!):

On my 3 year old development PC, the process takes about 4 seconds to produce the 1024 x 681 pixels picture. On a Galaxy S6 Edge, the same process takes about 1 minute and 35 seconds. This means that I will need to optimize quite a bit (if possible) and that processing large images will take a long time...

Hey, at least it works ;)

Best regards,


06/06/16 update: you can download (at your own risk!) an Android executable here

You will need to allow your Android device to allow untrusted applications to be installed, so it's for advanced users only.

Just load or take a picture using the bottom buttons and then click on the FotoSketcher logo in the top left corner to launch the effect.

This is a proof of concept, which allows you to take pictures or load them from your image gallery and turn them into watercolors. 
You can also save the result in the image gallery.
At this time, it os not possible to modify the effect parameters (it will look good on some images, not so much on others). 

Don't hesitate to let me know if it works for you or if you encounter any problems.  

Sunday, April 24, 2016 new responsive website

Hi all,

I have finally updated the FotoSketcher website to be responsive, with the help of my friend Martin (thanks, Martin!).

More and more users now surf from phones or tablets and the old website was no longer adapted. This is also relevant as I am currently porting FotoSketcher to the Android platform.

So far, FotoSketcher on Android can :
  • take photos with the phone camera
  • open existing photos from the image gallery
  • zoom in or out on the photo
  • apply simple image filters (sharpen, Gaussian blur, contrast and brightness)
  • apply a simple pencil sketch effect
As you can see, there's still a lot of work to do :)

I'll keep you posted and for those of you who want to test it, I will upload an apk file in the next few weeks.

All the best,

Just a quick word

Hi all,

Just a quick word to let you know that I've been very busy at work since the beginning of this year and unfortunately I have not been able to spend as much time as I wanted on FotoSketcher (PC program and future mobile app).

But, I'm still working on FotoSketcher and I will keep you updated here.

In the meantime, here is an abstract piece, made entirely in FotoSketcher 3.20 (click on image for full view):

untitled - March 2016 - made in FotoSketcher 3.20

This was a fun experiment. I first pasted a screenshot of my desktop in FotoSketcher and reduced the size to 1% of the original dimensions. I then increased the size by 300% a few times and ran the Painting 10 effect a couple of times.

Best regards,

May 2016 bring you joy and happiness :-)

Regarding FotoSketcher, I'm currently working on various fronts:
- tweaking and improving Painting 10
- researching a new painting effect
- porting some effects to the Android platform
- testing WineBottler ( for our frustrated Mac friends ;-)
- finishing the new website (live soon)

Here is an example of Painting 10 on an image from the great website (click on image to view a larger version):
