use masking and gradient if you want to get that effect. medyo nakakapagod nga lang kasi madami yan.

sir applying desaturate won't get the result you wanted..it will simply turn that raw image to black and white, which is very different from the result that you are aiming Very Happy

i did this process to get as close as possible to the second image...
desaturate > brightness & contrast >

Image to black and white Screenshot024hk
then select each strands using marquee tool then apply surface blur
(just play with the settings until you get your desired look Very Happy)

sana makatulong Very Happy intay pa tayo sa mga master if there's a faster way to do it buttrock

@ sir fpj999, sinubukan ko yung trick nyo at yun ang pinaka-malapit na resulta, salamat po.

@ sa lahat, salamat po sa reply, yung desaturate di po nakukuha,

@ ma'am KettleRenderer, sinsya na po medyo sablay din ako sa question ko, hehehe bali yung sample dito ay na-Downlaod ko lang sa net. so di black & white tawag sa ganyang image, anu po ba? nalilito rin po ako.

may ini-expiriment lang po ako.

eto po yung eni-expiriment ko, nakita ko yung resulta nya
eto yung sample image
Image to black and white Arch40_082_02

1. A simple gray scale image made in PS as displacement map
Image to black and white Greyscale

2. eto naman ginamitan ko ng displacement na ginawa rin sa PS with disaturate at etc. mapapansin natin na yung dsplacement nya sira-sira this is because the map is not clean pure white and black.
Image to black and white Mybump

3. eto naman ay ang pure black and white yung image na paran z-depth na displacement, yung effect nya ay mas clean and clear.
Image to black and white Originalblackwhite

at nagtest rin ako ng ibang image na ginawang kong grey scale sa PS at yung nakita ko ay yung pure black na part ay hindi mag-didisplacement at yung light or medyo black ay yun ang magkakaroon ng displacement. so sinubukan ko to sa isang roof tile, ganun ang naging resulta kaso, hindi masyadong clean kasi di tulad kasi ng image na parang z-depth,
and now sinubukan ko yung advice ni sir jefferson, so I model it and use the use z-depth pass, so eto since di ako marunong sa max magmodel sa cad nalang, Image to black and white Cad

at pagdating sa max, yung camera from top pointing to bottom, then render with z-depth, yung z-depth nya ay ginamit ko as displacement here is the z-depth pass Image to black and white Myzcroped (by the way nahirapan ako sa zdpth di ko kasi alam yong tamang settings kaya pagpagsensyahan nyo na po)

at eto yung resulta nya Image to black and white Sampleofmyzdepth

kung simpling grey scale lang di ko nakukuha yung ganitong resulta.

@ sir jefferson, salamat sa tip sir

@ sir edosayla, yung pixplant sinubukan ko po yung (trial version) ganda po nya kaso po wala po akong makita na pwedi syang maggenerate ng parang z-depth straight from the image, pero ok siya kasi automatic may specular, normal etc na yung image mo, kaso yung trial may logo nila kaya di ko ring magagamit. salamat po sir ed sa info ng pixplant.
