Converting to B/W...

Just as Austinspacce said of sharpening...
There are a lot of different ways to convert color to b/w. One way which produces a different tonal feel than the more common RGB->Grayscale conversion is to use Lab color Mode. Lab color mode converts the image to a Lightness, a, and b, channels. The lightness channel is the value component of the image, a is the red-green component, b is the blue-yellow component. What we do is keep the lightness channel and delete both color channels. Here's how:

Open image. Click on Image-->Mode-->Lab Color to convert from RGB to Lab color.
Click on Windows -->Channels to open the channels palette.  You should see a palette with 4 channels Lab, Lightness, a, and b. Drag the bottom channel b to the trash can icon.  The channel palette names will change to Alpha 1 and Alpha 2. Drag Alpha 2 to the trash can icon. You are left with 1 channel that just has the tonal values from the image.  You must convert the color mode to grayscale when done by clicking Image-->Mode-->Grayscale.  Supposedly, if you try to convert back to RGB with no color info you can confuse PS.(I haven't tried it)

You now have a grayscale image with a different tonal structure than just converting to grayscale.  You may or may not like the effect but it's another tool in the tool pouch. Experiment and have fun!
There are other ways besides RGB-Grayscale and zeroing the saturation. If you have one let everyone know about it.


Sharpening Images in Photoshop

The great thing about Photoshop is that there's a dozen ways to do the same thing, and this includes Sharpening your photograph.

When sharpening an image for presentation the easiest thing to do would be to choose Filter-->Sharpen-->Sharpen. However, there's no control over the results and generally your photo will be over-sharpened to the point of looking jaggy. You can "fade" the Sharpen effect here by choosing Edit-->Fade Sharpen but you have to guess at the percentage you want to change the sharpening, and this might take awhile to decide.

I don't pretend to know the capabilities of all the Sharpening tools in the Filter dropdown menu; there's Sharpen Edges, which seems to choose the highlights to sharpen; Sharpen More, which is even more extreme than just Sharpen; and Smart Sharpen, which can do wonderful work on an image and is worth its own tutorial by some enterprise-minded Photoshop fiend.

My tool of choice is File-->Sharpen-->Unsharp Mask. It seems to be the easiest way to find the right balance between crispness and softness in an image. Try it on an image of yours. When you choose it, you'll be confronted with a dialogue box. Type in these settings and see what you think: Amount: 50%. Radius: 1.0 pixels. Threshold: 0. You can experiment as much as you like, of course, to get the most pleasing result.

I just discovered (via PhotoshopTV) a great addendum to this hint. Open your image, which is more than likely in RGB mode. Convert it to Lab Color by choosing Image-->Mode-->Lab Color. Then, in the Channels Window (activated via Window-->Channels) click on Lightness and then apply the Unsharp Mask filter. Convert back to RGB, and you'll see a difference in the quality of the sharpness. By choosing to work just on the light parts of the image, it really sets it off against the darker.

Here's an image where I've applied the Unsharp Mask filter at the settings mentioned above: RGB.
And here's the same image opened in Lab Color and then the same Unsharp Mask settings: Lab Color. What do you think?

If you have your own methods for sharpening an image for presentation I'd love it if you shared them in the comments below. Please focus on sharpening, though--save other hints for future posts!

Has anyone had luck with this feature in Photoshop CS2? I have had past problems with jpeg artifacts and this is supposed to help with that.

Anyone know more about it?

How much "story" should be in a story?

published 3/25/06 2:01 PM
I've noticed that in the comments I've received about two of my longer stories, people have mentioned the length of the story.

Is there an expected length of stories?
How long is too long?

I'm asking because I don't want to be reported to the authorities.

One of the stories I posted I knew was long with a lot of photos. I posted it as a photolog so I wouldn't take up frontpage space.

Would you (subscribers, readers, webmasters) suggest longer stories stay in the photolog section rather than the frontpage?

PhotoShop Question

Well the software in not actually photoshop, but it is a similiar program.

I am wanting to know how to convert a colored photo into black and white, then change a certain portion back to color.  I am assuming it will have something to do with layering?

I already know how to just convert from color to black/white.  

Any help will be appreciated.


Pixelated photo

When I went to Washington County I had set my file size on my camera smaller than what I typically use.  I forgot to switch it back when I did a group cast photo. When I went to have an 8x10 printed...some faces are pixelated.  Any ideas aside from redoing the shoot?

What's wrong with this histogram

My little postcard camera (canon powershot a70) is getting old... a couple times now, the lens goes wonkie (that's the technical term I found on the internet) and instead of an image on the screen, there's lots of horizontal lines. The standard Marine Corps technique usually works to fix it (thump it a couple times) but I think all this Field Maintenance is making my pictures a little worse. Here is the Histogram for one of my recent potraits... I don't know if there's enough information in this image, but I don't think the little white chasms in the regularly smooth curve are good things.

Couple questions:


  1. Is my interpretation of the histogram correct?
  2. What other information do y'all need to tell if my camera needs work/replacing?
  3. Is there anything I can do about the images I've already taken? (In photoshop...?)
  4. Anyone willing to part with a Rebel for cheap? =)
Thanks for the help and advice...

Olympus has issued a recall on a number of its film cameras.
The flash unit can overheat and cause burns. If your Olympus film
camera was purchased between 1989 and 1995, contact Olympus

Help. I just can't get this right

I spent a long time trying to get shots at Karate class tonight.  Nothing worked.  This is a terrible place to take pics.  Lighting stinks.  I thought I actually got a few good shots but when I got home they stink too.  Not sharp.

What can I do next time?  I can't seem to fix these.  Wanted to use them in a news article.  Any and all suggestions welcome.

Shooting with a Canon Rebel XT, kit lens, built in flash.

Thanks

WOW It finally happened. I'm here and I'm in. Now I need to know what exactly I can do that I couldn't do before.
I've noticed when someone comments to a story that they can add a picture to the comment. Can I do that and if so, how?

"Photo Quality" printer

I'm trying to pick up a job shooting portraits at the Navy's Birthday ball here in a few (6) months. I would like to offer "While you wait" printing so people can go home with their portraits instead of waiting a week or so for me to send them off to a lab then mail them back out.

Before I run out and chase printers, has anyone had good or bad experiences with printers, paper, ink, etc?

Thanks in advance!

A question about using Mozilla

Has any one every lost their bookmarks while using Mozilla Firefox?  I have lost mine twice and it is getting annoying.  They are there one day and the next day they are not.  If they are hiding somewhere I cannot find them.  I had a great list of photography sites and now they are in cyberspace somewhere.

You asked... How did you do that....

Waterproof printer paper that can be wiped clean
You can buy "water-proof" printer paper for a little more than a dollar per sheet -- the retailer claims that it is water-proof, crumple-resistant and can be wiped clean.
