Topic: Photo2Mesh Portraits
I am working on some printed portraits of my daughters as a Christmas present. Here is the first go around which is pretty good, but I want to make some revisions-

I inserted the @pause command between the last of the base layers and the rest of the portrait layers. It tells Repetier to stop, and then you can move the extruder aside (don't hit the endstop) and change colors, and pick up where it left off when you press continue (this does not work with SD card printing). Printed at .1mm
Here are the jpgs I used with Photo2Mesh


For starters, I'm going to skip the smoothing. I wanted to diminish the solid layer pattern on the base as much as possible, but I like the look of the portrait as printed. I need to increase the contrast on Zoe (with the braids) to give her cheeks more definition. I need to lighten Lily's shirt so it comes high enough to print in more than one layer, enough to be mostly opaque. As it is, the skin beneath her shirt reads as a weird neck.
I lightened their pupils so they wouldn't turn into deep holes in the print. They need to be darker enough to provide definition, but I wanted them to be mostly at the level of the rest of the eye. I raised the blacks in the face and clothes enough to keep them above the background level, but tried to keep enough variation in tone to provide more dimensionality in the print. I boosted the contrast a little more in Photo2Mesh, which is what pushed Lily's shirt too far down.
I ran noise removal in Photoshop on Lily and also the Median filter. Median smooths out a lot of noise and reduces detail a fair bit creating a soft look that doesn't quite go so far as being out of focus. The detail lost was too fine to show in the mesh anyway, and this way it isn't trying to reproduce that noise as geometry.
The prints are 100x100, and took about 2.5 hours to get to the color change, and then another couple hours after that. Sliced in KISSlicer. In Photo2Mesh I set the base to 1mm thick and the mesh to 3mm. The STLs came out to around 2,000,000 faces which I decimated to around 500k. KISSlicer sliced them in about 3 minutes. I imagine Skeinforge would take all weekend.
