Need some facial reconstruction help
So I'm just trying to learn how to remove glasses from people's faces, but the hard part is that it's very detailed behind their glasses, like possible wrinkles they make with their facial expressions or the dark rings round people's eyes (make-up, natural shape of the eye, etc) So I decided to use this as an example - http://images.ljhooker.com/agent_pages_au/92_1_Young%20woman%20wearing%20glasses%201.jpg However this is my poor attempt - http://i111.photobucket.com/albums/n126/Jdeadevil/Untitled-1-4.jpg My main focus here is the ring of her eyes, the pushed in nose like a na'vi from Avatar, and the blue weird patches in the hair. Any help would be awesome, thanks.  |

What I do not understand is why you become pixelated. One of the first things I learnt here from Nick is you need to resave the image at 240 - 300 pix per inch. Then manipulate. You compress afterwards to meet ~100k limit for the post. Otherwise I think you are going in the right directions. We had a challenge in the past on glasses removed http://www.howtocheatinphotoshop.com/cgi-bin/simpleforum_pro.cgi?fid=06&topic_id=1235724290 there are some good thoughts there, |

I don't understand what you mean about the dimensions, could you elaborate please?  |

Re: Need some facial reconstruction help
ok. Go Image> Image Size. For us here, set size about ~42cm x 32cm and >>> resoltion 240 or 300 pix per inch And then below that in the window save the algorithm Your image will become very big after that. If your machine cannot cope, you may try smaller. When you get more layers it gets very memory intensive, and CPU. My machine starts grinding to a halt... So just my thoughts |

OK, in simple terms an image is made from a set of pixels and the number of them determines the resolution and the size the image will be when printed. The more pixels you have in a square inch, the finer the resolution will be. If the picture is say 1 inch X 1 inch @ 50 ppi (pixels per inch), then it will comprise of 50 X 50 pixels = 2,500 pixels. If the same image was at 300 ppi then you would have 300 X 300 = 9000 pixels. If you zoom right into an image at pixel level, you will see that each pixel holds a colour, so a low resolution image as described above will look blocky as Trevor describes. The image size dialogue allows you to resize an image, but merely increasing the size will mean that you are spreading the same number of pixels over a greater or lesser area. This is why PS allows you to resample / scale the image, so the physical dimensions stay the same, but the pixel content changes. It does this by a process called interpolation and uses a number of methods to do this , as you'll see from the bottom of the dialogue box. I tend to use Bicubic Smoother. There are also plug-ins you can buy, which some maintain do a better job than PS, but I've always found the normal function works well enough. It's worth reading up on this further and playing around with the dialogue box to see what happens. You will never turn a very low res small image into a pin sharp larger work of art, but you will smooth out the creases a little. Nick |

So it's the closest you can do to increase an image without pixelating it? Well the image I got there was just something I found on Google Images, I haven't done anything to make it pixelated. Infact that's why I decreased the size before I uploaded it, but for some reason it's pixelated again.. |
