Ali- if your read page 1 of this thread you have an indication how it works and you can start giving it a try.

In very short- I don't want to take anything away from Springtides article- you open your image in RAW pay ONLY attention to the highlights and adjust your image accordingly. Open it up in PS and immediately save it under a different name. Go back to your RAW file- open it once more in your RAW converter- this time you pay attention ONLY to your shadows and adjust your image accordingly. (Ignore completely that you probably blow out the highlights!) Now open this version in PS. Go back to your first saved copy > select all > ctrl +c (=copy) > click the "shadow" image and paste it on top of your shadow image> ctrl + v. Now you have in fact two copies of the same image on top of each other- one adjusted for the highlights and one adjusted for the shadows. Now you just need to "erase" the parts you don't want from the top layer to look through to the bottom layer.

The "erase" can be done either by really using the eraser tool/ by masking and painting on that mask or if you want it perfect you would use a mask and the gradient tool (black to white or white to black) ON that mask which would then blend both images perfectly (similar as if you would have used a gradient filter but with the advantage that you can use it on multiple spots in your image => sometimes you have more highlight areas than just the sky)

Now this should perhaps helps you going- but I am sure that Springtides' article will explain it much further.
Happy photoshopping
Stef. :P

So Stef, how many marks out of 10?  I can see the red pen and highlighter already!!!

Anyway, hopefully it will be published very soon!

If its anything like the advice you gave me, in our many discussions on the subject then it will be very good.

It's a little OTT, but basically it was taking this....



And about 30mins later, getting this....



Although this was purposely done a little OTT!

(Although trying to document it took more than 30mins!)

:D It does lift the shot even more, but the colour etc is incredible (even if deliberately OTT)

Springtide- sorry to come back soo late. I have answered you earlier on with a personal email. Your tutorial is fantastic- spot on- very simple to follow. There are always a thousand different ways to do things in PS or in any other post-production software and it was informative for me to see how you do it. There is never a right or wrong as long as it works! Thanks again for such a good tutorial!
Stef. :P

A late response for you, but a fast response for most other members!

And thanks to Stef for being another pair of eyes and completing the review in such a short time!!

Off out tonight and away for the day tomorrow - so hopefully will get it posted tomorrow night!

OK, hopefully (on the second attempt) it's been submitted for mod approval!

It took me a little while to work out how to cut and paste from Word into the article tool ;)

Ho Boy. I just re-read most of this thread. My eyes have glazed over--again.

Simon, your work is outstanding. You and Rob do the best shoreline images. And Stef's knowledge...just blows away this old Luddite.

I MUST learn this stuff for my new project. But, alas, I suspect I will be hopeless in it and have to sell all of my gear and join a convent. ;)

Can't wait to see you article. Will give it a shot. Thanks all. If I can learn half of this stuff it will be a miracle. Eyes starting to glaze again ...

Clive

Thanks for the kind comments Clive,

I am also looking forward to Simons article, we had some lengthy discussions last year about HDR, and i have taken a few in HDR but dont have the knowledge of it like Simon does.
If the article is anything like the advice he gave me, then its really easy too learn.

As for Simon and me doing the best shoreline images, when you live in the part of the world we do, its impossible to not to take good images of it, its so stunning all you have to do is press the shutter sometimes.

Thanks Clive for the kind comments. I don't really know what I'm doing in Photoshop also, but the last couple of weeks things have started to make sense a little bit more.

As Rob pointed out, seascapes are easier when you are close to Devon, Cornwall and South Wales :)

We don't get very many BIG skys though!

Been playing with my webspace, so a badly formatted version of the tutorial is available from:

http://www.peppernet.co.uk/ps/merge/merge.html

As I said, it's a little badly formatted (or should I say, poor HTML) as "Peppernet" only really exists for "having a play"!!!
