Channels and calculations in photoshop

Hey guys,
I hope everybody’s keeping well. I’ve been playing with channels, calculations and layers a lot the past while. So I thought I’d write up a quick photoshop tutorial that you can use on your photos & photography. It’s well overdue as it has been a long time since my last tutorial. This tutorial works best when there is a fairly solid colour in the background!

OK, so below is the before and after of this quick tutorial. This can be used on many different types of photographs with brilliant results. Without further ado, we’ll get cracking on the tutorial. If you’re already pretty handy with photoshop you can skip through to the conclusion for a fast tutorial! You can also download the source/.psd file here or have a quick look at the results.

Photo changed with Calculations and channels in photoshop

Choose one of your own photo’s or you can download my photo. Once you have a photo, bring it into photoshop and we can get started

 

Step 1

Open the Channels palette by choosing Window>Channels from the main menu
(by default it’s the tab right beside the Layers palette).
Channels Palette in photoshop
If you click on each channel, you can see the detail on each. For this particular photo, the green channel is best for what we want. Click on the top channel(RGB) to return to the original view and see all layers.

 

Step 2

Choose Image/Calculations from the main menu. Here we shall choose the green channel, blending mode of overlay and make sure that result is set to New Channel.
Calculations Dialog in photoshop

You will notice the photo has changed to black & white and there’s a new channel selected.

Step 3

While your new channel ‘Alpha 1′ is still selected we shall copy this layer. Press ‘Ctrl + a‘ to select all, now press ‘Ctrl + c‘ to copy. Click on the top channel RGB to restore the original shot. Now click the Layers tab and paste your layer ‘Ctrl + v‘. You should have something that looks like this:

Step 4

All that is left is to change the blending mode of this layer to overlay.

That’s it, job done.

 

 

Conclusion

Open your image in photoshop
Go to your channels palette
Choose which channel is best for this image (R/G/B)
Choose Image/Calculations from the main menu
Pick your channel, change blending to overlay and change result to new channel
Copy that channel over to your layers palette
Change the blending mode to overlay

Finishito – Job well done!!

Once you’re happy with that you can start adding little adjustment layers with curves/levels and they will make a big difference to the end result as you can see with some of the following shots.
Let me know what you thought of the tutorial. Also feel free to pop a link to one of your photos you tried this out on below!!

Peoples Photography 2009

Peoples Photography | Dublin, Ireland

This years Peoples Photography 2009 is a go! There has been a huge interest so far (almosot 170 photographers). Sadly, this means there are no more applications being taken for the time being. There will be a few places allocated on the day if you turn up though!

This is a brilliant weekend for everybody; Photographers, Tourists, the family, passers by and even pets! As always, the peoples photography takes place on the last weekend of August at Stephens Green, Dublin, Ireland. That means this year it’s on Saturday the 29th and Sunday the 30th.

This is one of the most enjoyable photography exhibtions I have been to in Dublin, if not Ireland!

Head on over to the official Peoples Photography Website to get some more info. Here’s my blog post about last years Peoples Photography 2008.

I hope to see you all there and don’t be afraid to come over and say hi!!!
(On the day, mention you heard about Peoples photography from my site and I’ll give you a nice discount on my photo’s ;-) )

PS – If you’re taking place in the exhibition for the first time this year, make sure to start printing early. It actually takes a lot of time to organise all the little things. Enjoy!!

Car Safety First

Well I had lots of fun taking these shots. Sticking my head out the car window going 140Kph down the motorway. After taking my other shot I decided it would be safer if I put my helmet on. Genius!!

So here they are!

Captains Quaters Wicklow Goal

Just two of the shots I have gotten around to processing from my great trip to the Wicklow Goal. A great place for a day out if you’re in the area! Scarey place, I can only imagine what it was like years ago

Believe it or not but this boat was up on the top floor of the prison, it showed how goods and slaves where moved in and around Ireland. The rest of the prison was a lot scarier and didn’t look as luxurious as this!
