hi this is Marty from Blue Lightning TV

0:00:13.830,0:00:20.250
I'm going to show you how to easily

0:00:16.560,0:00:23.400
create a vast star field amidst

0:00:20.250,0:00:29.279
interstellar clouds of galaxies and

0:00:23.400,0:00:32.219
faraway constellations create a new

0:00:29.279,0:00:36.590
document by pressing ctrl + on Windows

0:00:32.219,0:00:41.070
or command + on a Mac make the width

0:00:36.590,0:00:44.399
1550 pixels the height 870 pixels and

0:00:41.070,0:00:49.039
the resolution 150 pixels per inch then

0:00:44.399,0:00:51.780
click OK or press Enter or return if

0:00:49.039,0:00:52.920
your foreground and background colors

0:00:51.780,0:00:56.850
aren't black and white respectively

0:00:52.920,0:00:59.760
press D on your keyboard or click this

0:00:56.850,0:01:02.010
icon will fill the background with a

0:00:59.760,0:01:06.659
foreground color by pressing Alt Delete

0:01:02.010,0:01:11.790
on Windows or option Delete on a Mac go

0:01:06.659,0:01:15.110
to filter noise and add noise make the

0:01:11.790,0:01:19.460
amount 400% Gaussian and monochromatic

0:01:15.110,0:01:21.840
then click OK or press Enter or return

0:01:19.460,0:01:26.520
make a copy of the layer by pressing

0:01:21.840,0:01:28.950
ctrl or command J click off the eyeball

0:01:26.520,0:01:30.570
to hide the layer and click on the

0:01:28.950,0:01:35.909
thumbnail of the background to make it

0:01:30.570,0:01:40.439
active go to filter blur and Gaussian

0:01:35.909,0:01:44.159
blur blur it point 5 pixels and click OK

0:01:40.439,0:01:48.110
or press Enter or return we'll adjust

0:01:44.159,0:01:52.409
its levels by pressing ctrl or command l

0:01:48.110,0:01:57.439
for the input black type in 200 and for

0:01:52.409,0:01:57.439
the input mid-tones type in point 40 to

0:01:58.579,0:02:07.170
make the top layer visible and active go

0:02:03.210,0:02:09.330
back to filter blur and Gaussian blur

0:02:07.170,0:02:13.060
and this time

0:02:09.330,0:02:15.940
blur it to pixels open levels again

0:02:13.060,0:02:19.900
and this time in the input black field

0:02:15.940,0:02:24.610
type in 170 and for the input white

0:02:19.900,0:02:27.160
field type in 172 there are less stars

0:02:24.610,0:02:29.050
but they're a bit larger now we need to

0:02:27.160,0:02:32.250
blur them slightly to make them a bit

0:02:29.050,0:02:38.860
soft so go back to filter blur and

0:02:32.250,0:02:41.890
Gaussian blur blur it 1 pixel next we'll

0:02:38.860,0:02:44.560
give them a slight outer glow open the

0:02:41.890,0:02:47.500
channels panel if you don't see it go to

0:02:44.560,0:02:49.900

0:02:49.900,0:02:55.780
selection of all the stars and then open

0:02:52.989,0:02:58.150
back up your layers panel we can Trash

0:02:55.780,0:03:00.780
the layer of the larger stars since we

0:02:58.150,0:03:03.760
now have a selection of their shapes

0:03:00.780,0:03:06.670
click the new layer icon to make a new

0:03:03.760,0:03:09.180

selection of the large stars with white

0:03:18.070,0:03:23.470
selection is now filled with white due

0:03:20.440,0:03:27.790

0:03:50.889,0:03:55.720
with and without the large glowing stars

0:03:53.200,0:03:58.329
it'll make more of a difference once we

0:03:55.720,0:04:04.450

with black which is the foreground color

0:04:13.530,0:04:24.410
go to filter render and clouds change

0:04:21.190,0:04:27.320
its blend mode to color dodge

0:04:24.410,0:04:30.590
and we'll make a new layer under the

0:04:27.320,0:04:34.340
active layer by ctrl-clicking or command

0:04:30.590,0:04:37.790
clicking on the new layer icon in this

0:04:34.340,0:04:39.350
layer we'll brush in colors click the

0:05:51.790,0:05:58.090
constellations nebulas and other

0:05:54.230,0:06:02.480
formations go to filter blur and

0:05:58.090,0:06:03.169
Gaussian blur blur it approximately 80

0:06:02.480,0:06:07.070
pixels

0:06:03.169,0:06:10.490
I find that blurring the colors softens

0:06:07.070,0:06:15.890
it and makes it look more ethereal let's

0:06:10.490,0:06:23.960

I'll brush over an area that already has

0:06:36.620,0:06:42.349
a lot of color to increase the density

0:06:38.870,0:06:46.370
of its formations next we'll add a

it go to filter blur and Gaussian blur

0:09:01.880,0:09:09.120
blur 15 pixels

reduce its opacity to 90% next we'll add

0:09:21.690,0:09:27.120
