"Texturing Metal - Part 3 Making the Hole and the round...thingy" by Johny
Feather the selection and paint the highlights follwoing the lightsource like iv painted on the iamge ( you can variate, dont forget !! ) and dont forget to add subtle highlights ( 2 pxls wide in the end of the piece !!! ) .
For the shadows at this step they are a bit primary, do it like if you were doing a rivet, except that it gets cutted in the middle , so paint the shadows opposing the lightsource again , also add some but very slight near the side highlights, to give depth.
We will leave the primary shadowing and highlights for now...now we shall select the inner circle ( you can do it by unhiding the layer with the selection that we made at start , and with the magic wand tool click on the middle - the place where the supression will be ) , and feather it by 0.5 again.
Shadow the inner a bit, like you see in the image, hte process is the same as the hole, but i will follow it thou.
Shadow it again, but this time with a bit more strenght in the direction of lightsource, to give depth.
This time put a white highlight around the ring that forms the shape, with again a very small brush with some opacity, and darken the interior even more .
One of the most importants, is to add the highlight oposing to lightsource, as you can verify here .
Now lets edit the light we have previously made, but make a small patch of shadow below the highlight, this will give a more sensation of depth and add a bit more shadow below the shape
Add a more stronger shadow , and a small highlight with midtone selected, but make it subtle !!!
Now the hard part, add a very subtle highlight to the borders of the shape, and select the hole shape and select inverse ( dont forget to feather the selection!! ) , the start painting some shadows with the burn tool , just to get the general effect.
The basic is done, now all you have to do is to modify some lightning by mixing some dodges and burns in the right place, to give the effect of something spherical but at the same time conic
Now for the tricky part, we pick up the dodge tool again, and set its brush size to 1 pxl , put some low opacity, and flow Clockwise followint the shpere shape, to make a somekind of brushed metal effect, do the same with some burns, but not so itense
Are you still there ?? amazing !! glad you made it out till here :D , anyways we are almost finishing !! be patient !! for for the final detailing on this part we will make a shape, any shape, could be anything inside the supression , i made a "j" ( i know...lame ) and i selected its transparency and used color burn again on the metal ( dont forget...feather )
And to finalize, add this final highlight, a somewhat exagerated one , and finish some small details that you might want to change on the lightning :)
