Re: sharpening/skin softening technique...

I can't find the Christy Schuler tutorials anymore. Even Google cache doesn't help.

If someone has her old page saved or her video tutorial ... please share! I'm interested what she does.

Re: sharpening/skin softening technique...

If I understand correctly, you want to sharpen globally, but keep the skin from getting "crunchy"

yes?

Christy Schuler is having web problems. No she is not gone, and hopes to get the site back up soon.

Not that it helps the given situation, but at least you guys know she will still be around and can access the site (hopefully) soon.

Oh so you mean the smaller the aperture the better ?! for example on a 70-200 f/2.8 what would be an appropriate aperture to capture sth similar to those shots using studio flashes ? is there any specific logic behind it ?! :/

GT_max, Sorry it took so long to get back to you with a reply.

Unfortunately, the answer is "no." As the light rays passing the lens tube and the diaphragm, some may be diffracted. (This is where the quality of your glass/lenses comes into play) When the diaphragm is small (i.e., a small aperture), the amount of light that can pass through the diaphragm is reduced and hence the proportion of the diffracted and non-diffracted light becomes significant. As a result, the quality of the image is also reduced. Therefore, closing the diaphragm (i.e., using small apertures) all the way down to the smallest aperture may not increase the quality of an image. In general, the quality of a lens increases as diaphragm closes down. This improvement will reach certain point. After this, quality goes down because of the impact of diffraction.

But on the Bright Side! (pun intended)

The zone of acceptable sharpness is referred to as the depth of field. While changing the aperture (f-stop) will not have a striking effect on the depth of field for a distant subject or a wide angle (short focal length) lens, it can make a great deal of difference in a close-up or a photo taken using a telephoto or zoom lens like the 70-200 you mentioned. Thus, we can use smaller apertures for increasing the depth of field and by increasing the depth of field, increase the sharpness of an image.

A wider aperture (smaller f-stop number.. f/1.6, f/2.8) will result in a shallower depth of field. You can use this to keep either the foreground or background out of focus while maintaining the subject in focus. When changing the aperture setting, you will need to also adjust the shutter to maintain the correct exposure.

In addition to closing down the diaphragm (i.e., smaller aperture.. f/22, f/32, f/64), we can also focus at the hyperfocal distance. If a lens focuses at infinity, the depth of field starts at somewhere in front of the lens and extends to infinity. More precisely, from that point on, the scene appears sharp, and subjects between that point and the lens are out of focus. The distance from the lens to that point is referred to as the hyperfocal distance.

It looks like some of the shots presented were taken with the lens wide open at f/2.8, some at f/5.6 and others may have been stopped down to f/22 or smaller. For your 70-200 in the studio I would go no larger than f/5.6 or f/8 depending on the focal length used and might stop down to as little as f/32 or f/64 depending on your needs and desires.

This article F o c u s P o c u s may shed some light on making a Depth of Field Calculator.

Does that sound logical?
