Fashion: Post-Production Photoshop Tutorial


Phocus

-          Major editing such as colour temperature should be done in phocus.
-          Job info
> Destination: [RAW Files Destination]

-          ‘Adjust’ tab:
> colour temp can be changed
> colour correction- select colour with eyedropper tool & then change tint on colour wheel.


-          Modify:
> Change something about one image
> Select other images which we want to extend our changes to
> Click modify- this will give them the same adjustments.

-          Preferences:
> ‘Save Adjustments’ should be set to ‘Always Save’.

-          Export:
> export as TIFF

-          Naming of Folders:
> Main Folder- [name of project]
> [name]_preview
> [name]_raw
> [name]_tiff

-          When  saving on photoshop- save as PSD or TIFF
-          Check blacks for colour cast.

Photoshop

-          Image Size:
> Pixel dimension should never change
> unclick ‘Resample image’
> when changing document size- 110cm width, keep resolution the same
> ‘Save as’ when taking away info.

-          Use Ctrl + space to select ‘actual pixels’ which allows viewing at 100%

-          Dust/scratch removing:
> Create a new layer (make sure to always work on correct layer)- [Dust/Scratches] layer should sit on top of background with nothing in between.
> Spot healing brush Tool (100% hardness)- automatically samples, for even surfaces eg. skies.
> Healing Brush Tool (100% hardness)- (all layers) alt + select area to sample from eg. close to edges & lines.
> Clone stamp tool- use when the other two tools do not work (have ‘sample all layers’ ticked).
> Bracket keys can be used to increase and decrease the zoom.

-          Never use adjustments from top bar always from the layers section on the right.
-          Curves:
> Contrast & colour corrections
> S shape
> Use one curve for one change eg. luminosity, rename and then create another.

-          Masks:
> Select a mask on a layer/curve (if white everything is selected, if black nothing is selected).
> To select areas- use a soft & large brush tool.
> Shortcut to make mask black- command + backspace with the second colour square black or edit> fill> change colour
-          Use back slash key to highlight what has been selected by brush tool
> Alt + click mask to look for any holes in the selection.

-          Selective Colour:
> select a colour using eyedropper, choosing colour from a list & then slide bars to change tone
> use before curves to change eg. skin tone

-          Use arrow button in bottom bar & select document profile
> in photoshop always should be Adobe RGB 1998 file.
> monitors cannot represent all of the colours in colour space
> so do papers therefore colours will look different from screen to paper.

-          View> Proof Setup> Custom> Device to simulate: (set to profile given)- EP4880 imediaT Photo Lustre paper.
-          SP9800 is used to print at a larger scale.
-          Black point compensation & simulate paper colour turned on then turn preview on & off to check colour tone etc.
-          Gamut warning on with Proof Colour on (under View)- this shows any colours that cannot be represented by the monitor & therefore the printer will not be able to produce the colour (only happens with saturated image).

-          File> New> Size: A3
-          Click ‘Advanced’> Adobe RGB 1998

-          Print Corrections:

> flatten layers before doing corrections for printing (save this for digital hand in).

-          For printing:
> Image Size: 300 resolution, resample image, change width to 10cm
> Add a curve- brighter
> Flatten the layers and move over to new canvas which will fit around 12 on.
> Then undo flattening, hide first curve, add new curve to make brighter & repeat flattening and moving.
> Continue doing for 3-5 tests as if doing a test strip.
> Do the same with colour tone- warmer/ cooler etc.
> Also include an unadjusted image on test strip
> ‘Save as’ test strip.

-          Save final image as PSD for Bjorn to print with print adjustment layers included eg. Bright 1 curve
-          We should save final image as [title of project]_final_number.
-          Print test file with lower resolution- decide on print adjustments (name curves ‘Print Adjustments’) from test strip- move onto proof print file & Bjorn’s file.
