Dark HDR Image in Photoshop

Friday, October 29th, 2010

Have you ever come across this problem:

“When I open my HDR Image in Photoshop, it is very dark. What’s the best way to fix this?”

This is a very interesting question. If the HDR image you open in Photoshop is very dark it is because the dynamic range of the HDR image exceeds the display capabilities of a computer screen. The image may also look washed out for the same reason.

However, Photoshop allows us to adjust the preview so that the computer screen may display the image correctly. The preview settings are stored in HDR image file and they are applied any time the image is opened in Photoshop. They do not affect the file itself.

To adjust the image, you can use 32-Bit Preview Options that can be found under View -> 32-Bit Preview Options. It contains two methods:

  1. Exposure and Gamma method – you can manually adjust the Exposure and Gamma, the Exposure being the equivalent of Brightness adjustment, and Gamma being Contrast adjustment.
  2. Highlight Compression – it compresses the Highlight values in the HDR image to get it withing luminance values range of the 8-Bit and 16-Bit images.

And that’s how it’s done! :-)

Match Colour in Photoshop

Thursday, October 14th, 2010

Match Colour in PhotoshopHave you ever tried to match colour in two images in Photoshop?

Let’s say you have two images and you want them both to have the same colour tonality – now you can do that in Photoshop using Match Color! :-)

The way it works is that you can adjust colour tonality in one image to match it with the other image. You can take a series of images and make them match in colour so they look like images taken at the same time with the same colour conditions.

You will be using two images where one will be called source image and the other target image.

Make sure you have both images open and make the target image active. Navigate to Image -> Adjustments -> Match Color. This opens Match Color dialog box.

In the dialog box, at the top, you will see the name of the image that serves as a target – in my case Child.psd. In the Image Statistics area select the source image from the Source drop-down menu. Immediately you will notice that your target image changes the colour tonality.

No you can use Fade slider to fade the effect (to tone it down a bit). You can also adjust the brightness of the image using the Luminance slider and you can adjust the saturation of the image using the Color Intensity slider. When you like the effect, just press OK to accept all the changes.

I hope you enjoyed it and I hope to hear from you. You can contact me by visiting Contact page on my website. Here is the link below:

Open Type in Photoshop

Wednesday, September 1st, 2010

Photoshop Lightroom TV

Hello hello, Happy Wednesday to everyone! :-)

Two things today – PhotoshopLightroomTV Day! and OpenType in Photoshop.

1. Starting with another Episode of  PhotoshopLightroomTV, go to PhotoshopLightroomTV website to watch it! Great resource for learning Photoshop and Lightroom and it is FREE! ;-) Find out how to use Graduated Filter and Adjustment Brush in Lightroom! Very very nice.

2. Adobe together with Microsoft (something a bit unusual) developed a cross-platform font file called OpenType.

OpenType format uses a single font file for Windows and Mac, which is a great feature because you do not need two different versions of the font. You can move files from one platform to another without worrying about font substitution.

OpenType in supported in Photoshop CS4 and CS5 and it offers expanded character sets. It also offers expanded layout features, for example discretionary ligatures which are not available in TrueType and PostScript fonts. Thanks to that, OpenType provides advanced typography control.

More information on OpenType can be found on the Adobe website. Here is the link – OpenType.

I hope you enjoyed that. See you tomorrow! :-)

Removing EXIF in Photoshop

Thursday, August 26th, 2010

Good morning! :-)

Have you ever tried to remove EXIF information from the files in Photoshop? When you take photos, your camera automatically saves all the technical information about the photo – this is EXIF. To access EXIF in Photoshop, you can go to  File -> File Info, then Camera Data category in the dialog box that opens:

File Info in PhotoshopThis displays all the information registered by the camera including aperture settings, shutter speed and even whether flash was used or not.

What if you want to remove the EXIF? The information in Camera Data category is not editable. Here is the trick:

Go to Save for Web and Devices, File -> Save for Web & Devices:

Exif in Photoshop

On the right side of the screen, under Convert to sRGB, go to the submenu: Metadata and choose what you want to include with your file. To remove EXIF, just choose Copyright or None.

I hope this helps. :-)

Have a wonderful day!

Installing Photoshop CS5 – shall I keep CS3…?

Thursday, August 12th, 2010

Adobe photoshopHello everyone, it is Thursday already! The time flies :-)

Quite often I get asked this question from people on my Photoshop courses:

” I have just installed a new version of Photoshop (CS5 or CS4) and I still have CS3 installed. I don’t need both versions. Shall I remove CS3? Is it safe to uninstall it?”

Yes, you can uninstall previous versions of Photoshop, the new version is not dependent on the old version. You can safely uninstall it. You  may want to deactivate it before you uninstall so you could install it again if you need it later on.

If you use an old computer, try CS5 or CS4 out first and see if you are happy with it. It may not run that well on the old hardware, it is being optimized for new hardware in computers.

To De-activate it, go to Help -> Deactivate…  in Photoshop.

Just to confirm once again, multiple versions of Adobe software can co-exist without any issues. This means that you do not need to uninstall CS3 (CS4) if you want to install CS5.

I hope it helps :-)

Have a great day!

Can I clip an Adjustment Layer to more than one layer?

Friday, July 30th, 2010

Clipping Mask in Photoshop

Good morning everyone. I hope you are having a fabulous week. I know I am! :-)

Today a Photoshop topic.

This is a question I recently got from one of the delegates on one of my Photoshop courses:

“I have an adjustment layer that I want to clip to more than one layer in my layers panel. Can I do that?”

This is a really good question. By default, when you clip an adjustment layer and there are number of ways to do it, Photoshop will clip the adjustment layer to the layer that sits directly below.

What if you want to clip it to more than one layer, let’s say that you don’t want it to apply to all the layers below, just two or three of them.

You can group layers: Layer -> Group Layers or Ctrl/Cmd + G, change Blend Mode for the group from Pass Through to Normal and clip the adjustment layer to top most layer in the group! And you’re done! :-)

Have a fantastic weekend! See you on Monday!

PhotoshopLightroomTV Episode 3 launches on Monday

Friday, July 16th, 2010

Photoshop Lightroom TV

Good morning everyone. Today I just wanted to give you an update on what is coming soon.

Episode 3 of PhotoshopLightroomTV launches on Monday and I am currently working on it, putting it all together.

Just to give you a taste of what is coming, I am going to show a tutorial on converting one image into three!  :-)

There will be another tutorial of course, as well. I cannot tell what, you just need to see it for yourself.

And I am in different location again! You know I move a lot so different episodes will be filmed in different locations.

I will be also talking about using a tablet which makes a massive difference while working in Photoshop.

Change File Associations for Photoshop

Tuesday, July 13th, 2010

Photoshop CS5If you have a 64 bit system, you can have both 32-bit and 64-bit versions of Photoshop installed (installing 64-bit version requires 64-bit operating system, f.ex. Windows Vista or 7). You can also install just one of them.

If you install them seperately (some people do it) , Windows will pick up the latest version to default the file association. What it means is that if you try to open Psd file from your Windows Explorer, it will launch the default (read: latest) version of Photoshop (either 32-bit or 64-bit). This brings some troubles – what if you want to open all the files in 64-bit but the latest one you installed is the 32-bit version? When you double-click on Psd files, they will automatically open in 32-bit version.

Here is the trick to change it (this will require changing the Windows Registry but it will be easy):

Open the Windows Registry by running regedit.exe (press Win key + R key to launch Open window)

When you type in regedit.exe and press Enter, Windows Registry will open.

Navigate to  HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\edit:

Change the path to the version of Photoshop.exe you want to use (32 or 64 bit), and that one will be the new default whenever “Photoshop” is chosen as a file association.

And that’s it! I hope you enjoy that and remember – Be careful!  :-)

Customizing Colour Settings in Photoshop

Wednesday, July 7th, 2010

Hello everyone! Happy day to you!

One of the first things you should do before you start working with Photoshop is to set up Colour Settings. To do that, you can follow me using any Photoshop version (the same settings apply).

One of the reasons why we do it is because the printed images and the images used on the Internet are limited on the range of colours they can display. You also need to set the proper Colour Spaces depending how you are going to use the images.

To access Colour Settings, go to Edit -> Color Settings in Photoshop menu as on the screenshot below:

Colour Settings

The default settings look like on a screenshot below (North America General Purpose as Adobe is an American software).

Default Colour Settings

However, if you live in Europe you will need to change that. Here is the list of available options:

ColourRGB will mostly depend on how you use the images:
- if you put images online, you would set it to sRGB – default colour space for computer screens
- if you print images, it depends where you print them. You will need to contact your printer to find out what colour space they use. They may use sRGB (most high street photo labs use them) or Adobe RGB (semi-professional and professional labs).

For CMYK, if you live in Europe, the default used by all printers would be Coated FOGRA 39.

CMYK Settings

Down under Color Management Policies, I set all the options to: Convert to…

Convert To

I also select options:
- Ask when opening
- Ask when Pasting
- Ask when Opening

below so I get prompted what I want to do if the image I am trying to open or paste into the design uses a different Colour Space. Then I can decide how to treat the image (the dafault option from Color Settings dialog box will be selected).

When you are finished you can press OK to accept all the settings or you can also save them on the hardrive by clicking on: Save…

Saving the Settings

And we are done!

Have a wonderful day and… till tomorrow! :-)
