hmm
i'd like a tutorial on achieving

"glow" in pp portraits

Hi
As I am quite new here, I am still checking the different forums. And I came to an assignmet called Textures. Saralonde started it with a great mixture of texture and portrait. I love the result.
Any possibility of a tutorial or anything on how to use textures in postprocessing?
If there is already something like this, could anybody show me the link? I've been searching but found nothing.
Saludos y gracias.

I've seen a lot of post requests for Photoshop tutorials. I was in the exact same boat as some of you just a few weeks ago. Essentially I was afraid to open the program because all the windows and toolbars and menu options scared the bejeebus out of me!

Then I found a link to a youtube tutorial and it was only like 3-4 minutes long and I learned so much just by watching that. There are several out there, and some are total crap, bad audio, poor video quality, etc. The one I saw originally was really well done, easy to follow, good audio and video, and I ended up watching nearly all the tutorial videos he's posted. Now I feel like I have at least a good basic (and then some) working knowledge of how to use PS.

What helped most were the Tutorial 101 videos. These are longer (30-50 minutes) than the others (most average 4-6 minutes on specific topics), but the 101 gave a great basic understanding of all the tools and how to use them.

I hope it's okay for me to post this...

here's the link to the 101 tutorials

And here is the beginning page of all of his tutorials.

I hope this helps!!

I tried to find a way to search through this post in case someone else has already suggested it, but failed. So hopefully this isn't a double up.

I'd like a tutorial on how to use off camera flash units. Lighting is such a mystery to me. A couple of moments ago I was shining all sorts of lights in my hubby's face trying to figure out how to get rid of shadows :-P

Flash basics

On-camera flash, (forget the built-in flash) using a hot-shoe-mounted flashgun, directed straight at the subject is very flat lighting, possibly the very worst of all. There are ways that we can modify the on-camera flash to control our lighting. We can diffuse the flash by means of clip-on plastic domes, (think non-coloured Tupperware-type pots that will fit over flash head),or we can bounce our flash from ceilings, walls, off of reflectors, etc.,.
Balancing the light between existing light and flash is quite simple- Just remember that Shutter-speed controls existing light and Aperture controls the flash effect. You set your camera’s mode to Av (aperture priority) selecting aperture to desired depth of field. (ie: for weddings F8 does the job) Get a reading from subject. Take note of these settings. Now select M (manual) mode and use the settings you got from Av mode. Fit your flash to hot shoe, use manual flash. Try first maximum sync speed (usually 1/250 sec or 1/500 sec), then come down from here just adjusting shutter speed, and checking on monitor, until ambient light looks right. As for power setting, I like to start at ¼ power, then I can go down two stops to 1/8 and 1/16 power, and up to ½ and full power. (My flashguns only span from full to 1/16 power) For interior shots use the same method: If ambient light reads 1/125 @ F4, you will need to set aperture to F4, and set shutter speed at 1/500(if this is your camera’s maximum sync speed, or 1/250 @ F5.6 if that is your maximum sync speed, and bounce off ceiling. Adjust power of flash until it looks right in the monitor. This gives a ratio of 3:1 as a basic starting point. A big advantage, especially when photographing people, is to have the flash off-camera, so wherever you wander to get different angles, your lighting with remain constant. If flash is on camera, you would need to make adjustments each time you move out of the pre-set range of focus. Your flash can be triggered by radio transceivers (Pocket-wizards) or by means of pc cables. For wraparound, or cross- lighting, you could place your subject between the sun and your off -camera flash, using the sun as fill and your flash as the main, or key, light Ideally, indoor images should not show that flash was used, so for this to take place, modification is required. I use a black computer mouse-mat, which forms a half snoot and is rubber banded to the underside of my flashgun when bouncing off of ceilings etc., this ensures no direct light lands on the subject. You can choose of course, to use automatic mode for flash-or TTL, (Through The Lens) I just prefer the manual mode.
Problems occur when using flash under fluorescent illumination, where you will get a severe green cast over your images-Solution is to use a gel (Window green) over the flash window, and a magenta filter( FL-D) over the lens. These filters will lose you one stop of light, but the lens filter alone will do the trick, if you aren’t using flash. Why this works is green over the flash window equalizes foreground and background color temperature, and the magenta on the lens absorbs the green from both sources to neutralize the image.
Most cameras will let you select front or rear curtain flash set-ups, (Front curtain flash fires as soon as the shutter opens, while Rear (or second) curtain flash fires just before shutter closes) and for most types of photography Front curtain will do the job, If the subject is on the move however, Rear, (Second) curtain flash is the way to go, the reason being that if you were to use front curtain flash on a moving subject, the movement defining blur, especially against a black, or at least a dark background, would appear in front, and not behind the subject, giving the impression that the subject is going backwards. On the other hand, if you were to use rear-(second) curtain flash for say a portrait, and you are trying to capture a certain mannerism, you would not want the flash to fire too late and miss the emotion.

If you shoot at a party or wedding reception, indoors at night using the auto or programme flash setting, which is usually either 1/250 or 1/500 second, you will end up with ultra black backgrounds, and not the scene you saw. That is because the flash fired too fast to record background detail. Solution: set camera to shutter priority or manual mode, and adjust speed to between 1/30 and 1/8 second-these are normal settings for fairly dark conditions, because of the actual flash speed,. blur won’t be a problem. This is Known as “Dragging the shutter”.
When using Dragging method keep flash set to auto or ttl, as, unless you are comfortable with doing this , you could complicate matters. If you only have a point and shoot camera, use the night setting-the camera will automatically set shutter speed to allow background detail to be captured, BUT, you will need a tripod/monopod etc, as for night mode shutter speeds are likely to be a lot slower than 1/8second.
Flash doesn’t reach as far as you like? Up the ISO! -“Twice the distance, four times the speed”. For instance: If your flash has a Guide number (GN) of 25(metres (80 ft), the best you can expect is a realistic distance reach of 20 metres (60 feet) at Iso 100,so at Iso 400 you will get a realistic reach of 120 feet (40 metres),and at 1600 Iso, a reach of 240 feet (theoretically),but noise will play its part at high Iso’s.



If you are using an automatic flashgun, that does not give you fill-in values, just double the iso you are using. Meter the scene, select an f-stop for the DOF you want,set auto flashgun aperture to same f-stop, and take your shot,this will give a 2:1 ration-your fill will be 1 stop darker that the main subject.

Thank you Ken, that looks great! I've saved it to file to study it properly later on. I appreciate all the effort

I would love to see a tutorial for PS CS3 regarding Curves. Curves really has me stumped.

[zespri]

how to do self portraits successfully - I just tried and couldn't figure out lighting, focus etc... bah!

[kencaleno]

Ok, here's what to do: For a daytime shot)

1. get a chair to sit on

2. Put an object (I use one of my wife's dolls) on the chair so that the face will be where mine would be if I were sitting there.

3. camera on tripod with accessory flash in hot shoe, flash at 45 degrees to bounce off ceiling between you and camera, flash on manual setting.

4. Mode set to Av -Get an ambient light reading say Iso 400 1/60 @ F4

5. Set camera mode to manual.

6. Keeping aperture at F4, Set shutter speed down two stops to tame ambient light = 1/250 @ F4

7. Press shutter button down halfway to focus-take finger off

8. Set lens to manual-(this makes sure focus doesn't alter)

9. Set selftimer for 10 seconds-to allow you to get to chair and pose

10. Push shutter button all the way down and make for the chair!
(Set flash to 1/4 power to start with,then try different settings until you get it right)


I hope that you understand this, regards, Ken
