Hi Martina,
To Enhance the colours using PSCS I did the following.
Quick USM 100, 0.5, 0
reduced the brightness by 15 and increased the contrast by 3.
adjusted the shadow/highlight by 0, +20
tweaked the channel mixer levels to give more punch.
And finally put the image through neat image to remove any noise created.
I hope you like the reults.
Best regards,
Alan. |
