In this "Tips-Techniques" window I would like to share my Photoshop knowledge for those who use the program and do not have enough understanding for some of the current functions. Without pretending for ultimate accuracy in my suggestions, I will be available with some comments.
Regards,
George Veltchev

Sorry George, I am not sure what information you want to convey here.
Did you intend this thread to be a place where us users give tips or were going to give us some?
...... or did you want some questions?
Thanks .... Dave

Hi George
I have a question about sharpening. I am using Unsharp Mask in Photoshop with a radius of 1 pixel and a threshold of 0 going for 75 up to 150 % depending on the picture, normally I stop when artifacts are starting to show up.
What is your choice in sharpening the pictures?
Thanks
Tom

Hi Tom,

How are you my friend? Great ....simple question, which does not have necessarily exact answer and many can suggest different values.
In my experience I am applying twice sharpening, once the image is converted from RAW and exported to Photoshop ... which however is not always necessary I think. I am always advising all the adjustments to be made from the beginning, first from the RAW conversion software and then in Photoshop and finally when the image is reduced to the size of the requested 800pixels by Treknature, some very fine sharpening because the reduced image looses some sharpness naturally. So .... after the image is exported to Photoshop..the first thing is to enlarge the image to the actual pixels size in order to view the changes easily on your monitor ...then, I am applying the following sharpening settings: Amount between:200-500%, Radius:0,2pixels and Threshold:1 levels. That's all Tom, and then after all other adjustments such as levels, brightness/contrast, Shadow/Highlight(very useful tool as well), Replace color, Hue/Saturation etc.etc finally I am reducing the image to the mentioned +/-800 pixels and then I am applying the the sharpening once again this time even more gently with a smaller Amount values. The Radius and the Thershold I am keeping unchanged at the final stage!

P.S. It is obvious that the better the image the less sharpening is necessary, so fitting a good sharp lens in front of your camera is the ideal starting point, I guess!

Regards,
George Veltchev

Thanks a lot George
this is really helpful, I hope you don't mind when I am going on asking questions, this is a great opportunity to learn and this is why we are here!
Some pictures have a color hue due to wrong white balance. I have to admit that I do not shoot in raw mode for my bird and animal pics, simply because I need speed and memory to shoot long series (but I do now for landscape photography). Also the jpeg quality in my Eos cameras are extremely high, both in highlights and shadow (as you may hear I am looking for excuses why I still do not shoot in raw mode, best excuse is probably the fun factor with not to much post processing before seeing the real pictures).
So my second question is how to correct white balance in jpeg pictures.
Thanks a lot in advance
By the way I am starting to feel a bit lonely on this forum, obviously all other TN members are photoshop experts already ;-)

Hi Tom,
another great question, I think!
Well, I am using a simple trick to discover easily what kind of color cast is dominant in a JPEG picture ( if any ).
Simply, I am increasing the Saturation (not permanently...just for the test) to lets say +30. Then you can see much
easily if any of the color cast is visibly dominant ...for example if I feel that the image become to warm...I am
adding a bit of blue and cyan to correct it! Then I am taking the saturation back to the acceptable for the eyes level!
The same can be implemented when the image looks cold ...then I am adding Yellow and Red etc.etc!

Hi Friends,
It's possible to correct WB in JPG with camera RAW if you have CS4 and CS5.
It's limit but you can set it to auto or own or use the WB pipette to point an middle grey point.
Use Open as and set it to raw and open the JPG and the RAW convrter open.

Ya ...and also the white balance can be set easily and ofteen perfectly well with the Auto Curves/Auto Color or Auto levels!
But ...not always!

Thanks Gert and George
very useful!!!!
One more question, maybe more difficult
In landscape photography you often have the distant landscape with much less contrast due to heat, dust in the air, distance etc. If I want to have more contrast only in the upper part of a picture, how would you do that. I tried in selecting only the upper part by lasso tool but the junction between the selected areas is much too sharp and the result awfull. There must be plenty of possibilities in PS with masks etc, but what would be an easy one to use?
thanks folks
Tom

Hi Tom,
Maybe you can use two layers and do as you did and then fade the layer with the contrast.
This should be pretty easy.

Great question Tom and let me thank Gert for his valuable input in this regard. There are few ways as far as I know to increase/decrease selectively the contrast in some areas and that's what I do more often: Firstly I am selecting roughly the designated place by using for example the Lasso Tool, then we need to soften the selected edges somehow and this can be done easily if you go to Select>Modify>Feather ..and by choosing a larger number at the Feather Radius you can dilute the difference in the original selection ... once again question of practicing, but this particular way can be very effective in many cases. Please Tom ... try it! Another way to select an area from the image with softer edges is to go to "Edit in Quick Mask Mode" just above the two partly covered squares (for setting the foreground & background colors). When you click on that Quick Mask Mode tool, you need to go to the brash tool and by choosing an appropriate size brash you can start selecting the chosen area. As you can see by doing that the selected area begins to be covered in red when you are applying the brash. To make the corners on this "Red" selection even more fuzzier then just change the Opacity and the Flow of the brash from 100% to ...a lower values. After you finish with the selection click again on the Quick Mask Mode button, then go to Select>Inverse and then you have finally a selection with well adjusted, softer edges.

Hi Gert and George
brilliant, I am one of these users that only know 1% of their software, now I know what the feather is and that is exactly what I was looking for.
Thanks again
more questions will follow, it would be a shame not to use this personal tutorial with 2 profs.
