Merubah Gambar berwarna menjadi Hitam putih yang Artistik

Anda suka dengan Foto/ gambar berwarna hitam putih? Ada banyak orang yang menykai gambar hitam putih karena terkesan klasik dan artistik. eh tahu nggak sebenarnya berwarna hitam putih sebenarnya tidak semudah yang kita kita lho! membutuhkan beberapa langkah dan trik dalam membuatnya lebih menarik dan lebih indah dipandang! Ternyata perlu sentuhan artistik untuk mewujudkannya, tentunya dengan bantuan dari adobe Photoshop kita. nah disini yang diperlukan adalah penguasaan untuk mengatur tata warna dan pencahayaan adalah kuncinya.

• Langkah pertama:

Silahkan klik menu File => open untuk membuka Foto berwarna yang ingin anda sulap menjadi htam putih yang artistik.

• Langkah kedua:

Sekarang anda perhatikan pada jendela Channels. Jika jendela Channel belum terbuka atau terlihat oleh anda, anda dapat membukanya dengan cara memilih menu Windows => Channels.

Pada Pallete Channel Tersebut anda dapat melihat bahwa Photoshop sebenarnya memisahkan masing masing Channel red, Green, dan Blue. Nah inilah yang biasanya dikenal dengan sebutan RGB. Foto Ternyata Foto yang sebenarnya kita lihat merupakan gabungan dari ketiga Channel tersebut.

• Langkah ketiga:

Pada langkah ini kita akan mencoba mengenal Mode lainnya pada photoshop…yakni Mode Lab. Untuk itu silahkan anda pilih menu Image => Mode => Lab Color. Nah Lab Color ini membagi bagi warna gambar menjadi Channel “Lightness” atau pencahayaan, Channel “a” yang mewakili perpaduan warna antara magenta dan hijau, dan Channel “b” yang mewakili warna antara kuning dan biru.
Nah sekarang tugas anda adalah hilangkan icon mata  pada Channel “a” dab “b” lalu klik Channel lightness. Dan kini sudah jelas terlihat warna warna pada foto/ gambar anda telah menglilang.

• Langkah 4:

Pada langkah sebelumnya anda telah melakukan konversi dari mode RGB ke mode Lab Color. Pada langkah ini, kita akan lakukan pengulangan langkah tersebut sekali lagi konversi, yaitu dari mode Lab Color ke Mode Grayscale. Caranya silahkan anda pilih menuImage => Mode => Grayscale. Nah coba perhatikan sekarang pada jendela Channels anda hanya melihat satu Channel saja yakni “Gray“.

• Langkah 5:

Sekarang Foto/ gambar anda telah berwarna hitam putih, selanjunya anda dapat mengatur lebih lanjut dengan memberikan efek Blend Mode, seperti Multiply atau Screen. Silahkan anda duplikasikan terlebih dahulu foto anda dengan dengan menekan shortcut keywordCTRL+J sehingga tercipta layer baru bernama Layer 1.
Default Blend Mode pada layer 1 adalah Normal, anda dapat merubahnya dengan memilihMultiply ( Jika ingin menciptakan efek yang lebih gelap), atau memilih Screen (Jika ingin menciptakan efek yang lebih terang). Sebagai contoh saya memilih opsi Multiply.

• Langkah 6:

sebagai finishing, Jika anda merasa foto/ gambar terlalu gelap atau terlalu terang dari yang diharapkan, anda dapat menggeser Opacity dari mulai 0% sampai dengan 100%. Sebagai contoh saya memilih Opacity sebesar 30%. Namun tentunya anda dapat menyesuaikannya sesuai kebutuhan foto/ gambar atau menurut selera pribadi anda.

Silahkan anda bandingkan hasil akhirnya, walupun foto/ gambar yang tadinya berwarna hitam telah disulap menjadi hitam putih, akan tetapi hasil foto hitam putih yang dihasilkan memiliki seni tersendiri yang tentu saja berbeda jika anda langsung mengubah sebuah foto berwarna menjadi mode grayscale saja.
Nah ternyata tidak selamanya nuansa hitam putih itu selalu terlihat kuno bukan?

monggo dipraktekin langsung kalo berminat, Semoga bermanfaat ya

Photo manipulation: Surreal oceanscape in a bottle.

In this tutorial, our Photoshop Maestro is going to fit an entire oceanscape into a tiny little (magic) bottle!! Techniques here are pretty advanced, so we hope you'll be able to tough it out with us as we fit an entire ocean complete with dolphins, rough seas and a boat to boot!

We're going to use a lot of images this time around in our tutorial. So go ahead and prepare these images:

Bottle & Cork:

Place the bottle into our workspace, and remove the logo.

Tilt the bottle, and drag its blending slider to make the bottle more transluscent.

Change its color by first applying:

and then pull out selective color to further adjust the color.

Place the cork at the mouth of the bottle.

Mask the cork as if it were stuffed inside the bottle. Use a 50% brush to mask the portion of the cork that appears in the bottle to give it a more opaque look.

Decrease the brightness by dragging curves.

Further darken the areas as shown, as that area comes in contact with water.

Water and Ocean surface:

Here we can sketch how much water we want to fill up.

Using a blue brush draw shapes according to our sketch. We can change its blend mode to 'Multiply'.

Create a gradient (bright to dark) on our water to give an impression of light filtering through.

Next, copy a portion of the ocean into our workspace. Erase areas so that we can get the ocean surface that we want.

Create a meniscus effect of sorts by applying these to blending options:

Change the hue and brightness of the ocean surface.

We can add splash effect in the bottle (sea water crashing), simply by using a portion of the rough seas image. Copy and mask off excessive areas like so:

Fisherman & Boat:

Import the image of fisherman. Resize and place it accordingly.

Mask off unwanted areas and adjust the color so that it matches its surroundings.

Reduce the opacity to around 75% to give it a glassy effect.

Add the bottom of a boat by using image of another boat. Once properly masked off and placed, set it's opacity to 30%.

The long paddle seems incomplete, so we are going to draw it. When done, use the burn tool to give the paddle some depth.

Seagulls & Marine life:

Copy the seagull image into our workspace.

Drag its blending slider to quickly blend the image.

Mask off excessive areas.

Have the dolphin image transformed and desaturated.

Change its blend mode to 'Overlay',

and erase excessive areas.

Next up, add in some jellyfish employing methods similar to the dolphins.

Import image of a coral reef and place it at the end of the bottle.

Erase areas as shown, and add in 'Drop shadow' blending option according to settings shown below:

That empty area will be used to fill in some sand. Select that area and fill it with white. Then. have our foreground and background color in two shades of brown, and hit Filter > Add noise. Blur and sharpen the sand to your preference.

I've added in tiny sea shells and starfish to spice up the sand area.

Bubbles:

Draw shape similar to below. I simply draw a hard edged circle, and use a soft brush to erase the center. Once done, define it as brush preset.

Use the brush settings as shown below (or similar settings), we can then start to paint our bubbles. Place some around the reef, the oar, and tails of dolphin.

Light rays and ambience aura:

We can refer to this tutorial (http://www.123rf.com/blog/blog.php?idblog=b1000107) for the makings of underwater aura.

In a nutshell, what I did was render clouds and difference clouds, and also applied a blur filter after. Remove excessive areas, change its blend mode to 'Overlay' and tune its opacity.

Same goes to light rays.

Additional Elements:

Adding in a faint sky and clouds background.

Mask off areas deemed excessive and set opacity to 20%.

Adding cracks to the bottle. Import this image.

Warp and transform till we get conformant shape:

Erase those extrusions to beyond the bottle.

Set it as 'Soft Light' blend mode.

Duplicate it and nudge it a few pixel downwards. This gives an impression of a thick glass bottle.

Go to our bottle layer, and erase according to our crack texture.

Introduce sunrays from the top:

Once done, we can start to add shades and shadow to our bottle. Draw an elliptical shape and feather that selection. Then, simply fill the selection with black color on a different layer. Transform and adjust the opacity until we achieve the desired effect.

Further add shades and highlights to the whole bottle, and we're done.

In the final image, I've added in a hand into the whole composition to give it some sense of scale and upon inspection, viewers will realize that its a small magical bottle.

and never squandering a chance to take things to another level, I created an alternate output. I hope you've enjoyed this tutorial!
