Step 3: Fine tuning

These should be self-evident:

If the pixels are too large, you have shrunk the selection too far. If you think they should be half the size, only shrink half as much.

If the pixels are too small and they don't obscure the image enough, the selection needs shrinking more. As above if you think the pixels should be twice as big, shrink the selection twice as much.

This is more subtle:

You'll notice that in this series of images the guy on the right loses an eye. The original selection was 71 x 72 pixels reduced to 8 x 8 pixels - Paint has rounded 7.1 x 7.2 pixels up. When this was stretched back the selection ended up as 80 x 80, a little over the original size.
This is why the dimensions of the selected area are important. Look to the lower right of the Paint window as in step 1, and select 'round' dimensions which will scale back easily.
All this being said, the effect still worked.
Nice, and simple. Personally, if i want to hide something, i go with drawing a black or white circle clean over the top. No reconstruction program is getting past that!!
The old fashioned 'letterbox' has a certain style to it I admit. But no reconstruction program can get back all the 5K pixels worth of data from these 64 - too much data has been lost. I should have referenced Kiteman's Unique Pixellation Indication Device, I'll go and do that now. L
I was thinking more like this...
Looks like something out of <a rel="nofollow" href="http://www.bbc.co.uk/doctorwho/Dr">Who?</a><br/><br/>L<br/><br/>But you've used something more advanced than Paint for that.<br/>
Hmm, there was an old Star Trek episode where an <em>alien</em> with <em>powers</em> did that to a young woman (how she could breath until they got him to fix her, days later, I don't know....<br/>
Charlie X I think you'll find. Personally I try and avoid photos of my fisog appearing on a family site for fear of frightening easily offended people!!!
Ugh, Charlie X. I hated that episode, and still do. Freaked me out the first time I saw it (still does). Of course, it was the second episode of Star Trek I had ever seen (I quickly learned that star trek got much, much worse in some other episodes....) <br>:D
I used photoshop (as that is what i had open at work) But the same idea can be carried out on paint using the ellipse tool. Indeed it looks just like out of who! (i am a big fan)
I forgot to say, thanks for the credit.
Well, that's where I got the idea from, all that time ago... L
I got my avatar from that instructable!
That's exactly what i was looking for, i have some photos where some people just need to be pixelated!!
Takes a few times to do it with a high resolution pic
I don't know who that is!<br> Indiana Jones?<br> <br> L
There is a free viewer called Irfanview that has quite a few special effects including pixalization. Its just select &amp; click to do this. I use it all the time &amp; it can do some amazing things. Cheers!
time to make some pixelated versions of my photos to put in my personal texture pack for minecraft. :)
Who are the three guys?
I do not know, just random guys...<br> I know at least half of<a href="http://www.instructables.com/id/How-to-make-a-Corvid-costume/#step10"> these people </a>though.<br> <br> L<br>
This is excellent!&nbsp;&nbsp;5 stars!&nbsp;&nbsp;Usually I have to use paint.NET everytime, but this is wonderful!&nbsp;&nbsp;Thanks!<br />
This is a good idea!<br /> <br /> ,,I post a picture of my self but pixalate my face (standing next to a water rocket). The big question is should&nbsp;I reveal my age!!
Age doesn't really matter, do it anyway.<br /> <br /> L<br />
Thanks!&nbsp;This is very helpful.<br />
Good one, I will definitely use this. 5*, and faved!
Nice, that was easy...even I could do it right the first time around :-)
Well it might come in useful somewhere, It was something I'd meant to do a long time ago. Incidentally, with the exception the Swedish rap-artist called Marcus (left), I've no idea who those guys are/were. L
Yes, I have already tried it once and it turned out perfect :-) Thanks again. It was very timely ;-)
Do you guys remember the case of the really nasty guy that pixellated his face with a swirl pattern, and passed around really bad pictures of himself? The undid the swirl and caught him. I wonder if people who can unswirl a swirl to get a face can unpixellate a picture like this.
In the swirl, the pixels have been moved, but they were all <em>there</em> - it just took some math to shuffle them back, like a huge version of those sliding-tile puzzles.<br/><br/>Lemonie's process deletes 90% of the information required to reconstruct the face, instead of just rearranging it.<br/>
Backtrack a moment there - Lemonie's method removes <strong>99%</strong> of the data, not 90%.<br/>
That one was different. The "Swirl guy"-photo was merely distorted, making it easy to reverse the process since most, if not all, of the information was kept in the image. Pixelization however incorporates removal of information from the image which cannot be recovered later on.
