be using this image for this being a

170
00:05:53,110 --> 00:05:56,770
medium format image it's like 9,000 by

171
00:05:55,029 --> 00:05:58,719
six thousand something like that if I

172
00:05:56,770 --> 00:06:01,539
need to use this for print publication

173
00:05:58,719 --> 00:06:02,949
and up down sampling it three times over

174
00:06:01,539 --> 00:06:04,330
well I mean it's but you know if I

175
00:06:02,949 --> 00:06:06,400
introduce a little bit of grain or a

176
00:06:04,330 --> 00:06:07,810
little bit of you know quality reduction

177
00:06:06,400 --> 00:06:09,250
probably not going to be noticeable in

178
00:06:07,810 --> 00:06:11,650
the end result if we're going to be

179
00:06:09,250 --> 00:06:13,719
blowing this up to the size of a large

180
00:06:11,650 --> 00:06:16,389
poster or a billboard then certainly

181
00:06:13,719 --> 00:06:18,430
becomes an issue so we can use this to

182
00:06:16,389 --> 00:06:19,659
target certain luminosities and of

183
00:06:18,430 --> 00:06:21,759
course this can be used in combination

184
00:06:19,659 --> 00:06:24,909
with any of the adjustment layers we're

185
00:06:21,759 --> 00:06:25,930
going to use in this course and you know

186
00:06:24,909 --> 00:06:27,190
the same thing applies for the

187
00:06:25,930 --> 00:06:28,900
highlights if we want to kind of taking

188
00:06:27,190 --> 00:06:30,610
things out of highlights we can do that

189
00:06:28,900 --> 00:06:32,760
using this slider once again splitting

190
00:06:30,610 --> 00:06:36,630
it to feather it out

191
00:06:32,760 --> 00:06:38,520
now the other option is to create

192
00:06:36,630 --> 00:06:40,470
something like this where we we target

193
00:06:38,520 --> 00:06:43,320
luminosities using channels so within

194
00:06:40,470 --> 00:06:45,180
the channels tab we effectively have the

195
00:06:43,320 --> 00:06:46,680
red green blue channel if we actually

196
00:06:45,180 --> 00:06:49,050
click down on these individual channels

197
00:06:46,680 --> 00:06:50,370
it's just not make a selection though so

198
00:06:49,050 --> 00:06:52,650
clicking down these individual ones we

199
00:06:50,370 --> 00:06:54,030
see that the extent of how much red is

200
00:06:52,650 --> 00:06:55,500
essentially showing through based on

201
00:06:54,030 --> 00:06:58,080
this mask so you can think of these as

202
00:06:55,500 --> 00:07:01,470
masks that are allowing certain amount

203
00:06:58,080 --> 00:07:03,960
of red green or blue through and so when

204
00:07:01,470 --> 00:07:05,490
we pick our our channel to use it kind

205
00:07:03,960 --> 00:07:07,890
of depends on what our purposes

206
00:07:05,490 --> 00:07:09,180
generally speaking red will show you

207
00:07:07,890 --> 00:07:11,220
know white in any areas where there's a

208
00:07:09,180 --> 00:07:13,230
lot of skin tone so it's generally kind
