Any suggestions on making someones skin look like that of a croc or snake? Similar to some of the work done here:

http://www.naturemorphosis.com/

I did this in Photoshop

1. Select the skin area, copy selection to a new layer.
2. Texturizer, load texture, snake skin.
3. Adjust scaling and relief to taste and apply
4. Adjust opacity and blending mode to taste

I think snake skin is a standard Photoshop texture

I've some skins, could be usefull for this. But i couldnt attach it 'cause of the 100kb limit.

upload to imageshack.us and post the link...

Thanks for the idea swampy! :)

Here's (http://www.retouchpro.com/forums/showthread.php?t=7933) a link on how to resize and upload pic for the forum.

I use Photoshop "Save for web" to save a jpeg just for uploads. I alwas save an original PSD file too.

here are 5 skins. Could be usefull.

cool thanks, havent had a chance to dl them yet but will let you know when i do! if you want to join in the fun, the contest is at the link in my sig. cheers!

skins are fun. we've done some of these before on RetouchPRO. they are fairly simple to do.

take your original image, dupe the layer.
add a blank raster layer.
copy your skin to the blank layer. best here if you can make this a seamless skin since you may need to add your skin more than once if it doesnt quite fill the whole layer.
then, pick your favorite blend mode on the skin layer. blends like overlay, multiply, soft light and others shld work fine depending on the effect you want.
now simply erase the parts of the skin layer that you dont want showing on the duped original layer. probably best here to use an eraser with a partial hardness and a partial opacity.

that technique is also useful in that now, by simply changing the blend mode on the skin layer, you can get several different effects all with the one skin.

here's one i did fairly quickly using handmadegod's snake skin. it probably would have been a bit better had i oriented the scales to point down, but i wanted the patterns in a certain way so i didnt.

i was a little sloppy with this, but you get the idea.

I think using Displacement filter works good on applying textures to skins. (just a reminder)

hey kraellin, that looks good and thanks for the tips!

@handmadegod- I am not good with the displacement map filter...

thanks, the rookie :)

Hi therookie.

It is not very often I get to play with displacement maps, so I had to have a go.

I used HandMadeGod’s Texture and a map made from the image.
I set the blending mode of the finished texture to hard light and then did some colouring. :)

Ken.

hey guys.

For the examples you supplied from that site I see that the texture does not wrap around the photos very well.

textures should react to the "bumps" that are made by the muscles and or expressions (like a 3d landscape)

If want I'm saying makes sense, you could try to creating that "3d" landscape of the face with the mesh tool on the liquify dialog.

it's like sculpting over the photo making the highlight pop out and the shadows deeper masking the areas like lips or any corners that would distort the face too much, then you can save that mesh. (dont apply the liquify tool) then you can select the layer with the texture, open liquify and load and apply the mesh you just saved.

play a little bit with the layer transparency.

I haven't really apply this to people skin but on other kind of surfaces work pretty neat.

Hi,

I remember trying something similar last year ....

attachment1 (http://www.retouchpro.com/forums/attachment.php?attachmentid=16870) and attachment2 (http://www.retouchpro.com/forums/attachment.php?attachmentid=16871) in this Thread (http://www.retouchpro.com/forums/showthread.php?t=9391)...



pindaro,

welcome to RetouchPRO!! :pleased:

.... and thanks for the tips!!!

not a crocodile skin, but an animal.

its very easy.

you desturate the part and add a new layer with skin and switch the layermode to overlay...and u can use the distort filter.
to do this:
desturate your image, apply a little gaussian and save it as psd. the apply the distort filter...

alright, i had another go at this, only this time using displacement mapping. i'd never used displacement maps before and wasnt even sure Paint Shop Pro 10 had this, but it does. however, like almost anything psp vs photoshop, the tutorials will not quite match up. psp's own help files were notably lacking, so i had to find a Photoshop tut and translate. it was pretty close, thankfully.

also, the tutorials for this on RetouchPRO are lacking as well, regardless of Photoshop or Paint Shop Pro. yeah, i know, so i shld write one up....bah!

actually, it's pretty simple.

your 'source' image is the one you want to apply the skin to. the 'target' image is the one you are applying, in this case, the skin.

first, open your 'source' image AND your target image. have them both open in Paint Shop Pro 10. dont combine them, just have them both open.

what most everyone forgot to mention is that you have to first desaturate your source image. save a copy that isnt desaturated too. you'll need it later. you dont need to use just one or two channels here. just desaturate the full image. you simply want a black and white in rgb 8 bit color.

now take your TARGET image and open the 'effectsdistortionsdisplacement map' filter in Paint Shop Pro 10. this will open up a new window showing the displacement tool. on the left will be a thumbnail of your image in black and white. click on that box and find the 'source' desaturated image in those thumbnails you now see. pick that image from the thumbs.

within this same displacement filter window, set to either 'stretch map to fit image' or 'tile map to cover image', whichever does NOT alter the shape of your source black and white. set to '3d surface', and 'wrap' and 'blur' to 1 (or to taste). set 'intensity' to about 10 (or again, to taste). set 'rotation' to 180 (or, to taste). then hit 'ok'.

what all that does is to take your target image and apply the source image to it and warp the target image to the contours of the black and white image as if the black and white is a height map of sorts. a height map is simply a black and white where the blacker it is the 'lower' the pixel is considered to be, or the further away it is considered to be. the lighter the pixel, the closer it is. but, there is a bit of a difference; a height map is for elevation where the displacement map is altering sideways or up and down with a bit of a displacement or warping. so, based on the black and white, you are altering the skin or target TO the displacement as dictated by the black and white source. (you really dont have to know any of this. just use the tool and it will do the thinking for you :) ).

ok. now you shld have an image that is a mix of the black and white and the target skin with the skin now being warped a bit or 'wrapped' to the black and white bumps/elevation/contours.

now, take your ORIGINAL color source image and add this as a new layer or your now mixed target and source. we can call the target and source layer as the 'effect' layer or 'mixed' layer. just put the original color layer over the mixed layer as a new layer.

now, here again you have some options. for mine as attached here, i simply used a blend mode of hard light on the original color layer that is now sitting over the mixed layer. you could also do other blends for other effects or even duplicate this layer and do some other blends. that's up to you. i simply used hard light.

you shld now have an image that is a nice mix of your mixed layer and your original. for just keeping this simple, i now duplicated the mixed layer and turned the original mixed layer off. on the duplicated mixed layer i now simply erased those parts that i didnt want the effect showing on, the lips, the eyes, the hair, the clothing and so on.

and that's it unless you used different sized images for the source and target. if you did do that, then now you simply copy merge to a new layer, use the selection tool on the copy merged layer to select out only that part you want and copy and paste that to a new image.

et voila', thou art done!

for the photoshop folks, here is a link to the tutorial i used to translate into Paint Shop Pro. http://www.graphic-design.com/Photoshop/displace/index.html i actually looked at several different tutorials and this one seemed the best and simplest to understand. just scroll down that page to where it says 'Star Spangled Girl' as a link and click on it and a popup will come up with the tutorial.

so, have fun and thanks for the introduction to displacement maps! :)

edit: in the stage where you desaturate, it's also a good idea to add some contrast to the resulting black and white.

edit: even though i DID the work right, i wrote this up wrong. i've now corrected this. in the original text i had the source and target mixed up in the early stages. (edited july 16, 2006)

hello again.

this is more or less what i was talking about earlier.


i did not spend to much time on the actual skin opacity and blend style, since i just wanted to show the animal skin reacting to the model (that is covered very well by the others post)

i did the same procedure that i explained on my previous post.

once i "contoured" the skin texture i just desaturate it and blend it in overlay mode over her own. (that's why it may look a little bit like scars)

please note the selection of and size of the texture is the most important part.

sorry for the noisy picture, it was the only one that i had on hand

cheers

wow, didnt see all the responses, this is great! I am trying to do the displacement map filter from this tut (star-spangled girl):
http://www.graphic-design.com/Photoshop/displace/index.html

but i get this look to my image after trying to apply the disp map filter:

http://img134.imageshack.us/img134/9990/flagfacesizeuz7.jpg (http://imageshack.us)

What is all the text about?

Anyway, great tut and effect Kraellin! I also really like the zebra manip of the girl and the thread you posted to Flora...

therookie,

ummm, not sure where you got the text but you've missed a step or done a step incorrectly somewhere. remember, you are going to use the flag as the target and warp/displace it with the girl. so, the flag is the one you want active and highlighted when you open the displacement map filter and the girl is the one that you open IN the displacement map filter. it's a little confusing in that tut with the image names he uses and you have to make sure you have the right images in the right order and locations. he might have done that tut with easier names like 'flag' and 'girl' rather than those long names where he reversed the words in the names. i had to go back several times and double check the image names to keep the procedure straight.

also, i've just edited my tut here in this thread cause i had one step backwards also. doing the work is easier than writing up the work :)

craig

here's one that's a little more dramatic. this used one of Paint Shop Pro's own displacement maps.

lol, me too! i wanted to sock him for using those names. I think i got it after i read another disp map tut. I didnt realize how cool of a filter it was!

I like your other submission too. Very cool effect! What source pic did you use for the texture?

I did this real quick once i got the hang out it:
http://img152.imageshack.us/img152/3882/babymaniptrsx9.jpg

ummm, therookie, which is my 'other submission'? the last one? and remember, the 'source' image is the one you use to make the displacement map, so in my case, it's the girl and i got that pic off of RetouchPRO in one of the forums here. the 'target' images were from the skins handmadegod posted and the last one from Paint Shop Pro's own displacement map images.

and on your latest image, very nice. now all you need to do with that is erase the bits where the eyes and lips are (or any other areas you might want to do).

pindaro - I think you are very much on the right track!

Here's some manips I did a couple of years ago using a very alike method as far as I recall:

I really like #2 and #3. You should compete in the competition we have at swank forum! :)

Any thoughts on this one?

http://img157.imageshack.us/img157/5219/girl3od7.jpg (http://imageshack.us)

it's been a while since i've done anything with displacement maps, but i thought i'd resurrect this thread because of some interesting things going on with Filter Forge. if you dont know what filter forge is, go to http://www.filterforge.com and check it out.

you might also check this link out at filter forge: http://www.filterforge.com/forum/read.php?FID=14&TID=1797 . this could make the whole subject of displacement maps easier to do once we've got it more perfected.

also, this thread shld probably now be moved to the 'compositing' forum.
