RE: Earthquake in Central Italy
Thanks for the update! My friend in Viareggio said they just barely felt it, their young son awakened but didn't know why. I've been thinking of all those displaced and killed by the quake. A sad day. Also the historical architecture that has been destroyed. Godfrey Some of Cartier-Bresson's most famous pictures were taken in Aquila degli Abruzzi, as it was then known. The town drew a lot of photographers because it was quite remote until relatively recently, and people continued to dress in distinctive local clothing for a long time after such things had been homogenized elsewhere. Set against the beautiful architecture it must have been a wonderful sight, and a beautiful place. I do hope it can be restored - because of the photographs I have always wanted to go there.

RE: Trading resolution for depth of field
Afyer 35 years of experience, I dont need no stinking formula, everybody knows the depth of field is image locked once you make the exposure. To change it ( increase or decrease the relative depth of field ), you have to change the in-camera magnification or fstop before shooting. You cant manipulate more or less image DOF ***after the exposure ***. Making a print larger or smaller doesnt change DOF, nor does declaring a the COC bigger or larger. To increase or decrease the image DOF you have make changes BEFORE the exposureAFTER is impossible. While not a formula, its a rule, DOF is proportional to f-number and inversely proportional to in-camera image magnification. Relative DOF = (f-stop number)/(in camera image magnification). These are the only two factors that increase or decrease relative DOF. These cannot be changed after the exposure. NOTE how, COC, Format, focal length, print size, etc do not matter. ONLY in-camera magnification changes and/or f-ratio changes can increase or decrease the relative DOF. Its very basic.

RE: Trading resolution for depth of field
NO I DISAGREE. Image DOF is the RELATIVE sharpness of objects in front of, and behind, the actual plane of focus. TO INCREASE OR DECREASE this relative sharpness you have to change the incamera magnification or f-stop. PRINT SIZE has nothing to do with changing the DOF of an image. While you can argue all day long that making a print smaller and smaller increases the perceived DOF, I dont, because all it does is make it harder to see the **same DOF**, its doesnt actually change the image DOF at all. Furthermore, I disagree with using the term critial to define DOF. Its not critical, its what it is, and thats simply the difference in sharpness of foreground and background objects relative to objects in the plane of focus. It doesnt have to be some critical barely perceivable difference, sometimes its huge and obvious. but in any case, if you want to increase or decrease that DOF, you need to know what CHANGES it, and what DOES NOT.

Re: Trading resolution for depth of field
This theoretical crap is boring. Quite wasting your time mass debating the theory go put it into practice by taking some interesting photos. DS 2009/4/7 JC OConnell hifis...@gate.net NO I DISAGREE. Image DOF is the RELATIVE sharpness of objects in front of, and behind, the actual plane of focus. TO INCREASE OR DECREASE this relative sharpness you have to change the incamera magnification or f-stop. PRINT SIZE has nothing to do with changing the DOF of an image. While you can argue all day long that making a print smaller and smaller increases the perceived DOF, I dont, because all it does is make it harder to see the **same DOF**, its doesnt actually change the image DOF at all. Furthermore, I disagree with using the term critial to define DOF. Its not critical, its what it is, and thats simply the difference in sharpness of foreground and background objects relative to objects in the plane of focus. It doesnt have to be some critical barely perceivable difference, sometimes its huge and obvious. but in any case, if you want to increase or decrease that DOF, you need to know what CHANGES it, and what DOES NOT.

Re: GESO: Wedding Rookie
First, I like them. Some - ok, most - could be enhanced, but then it's very easy to do that on a desk, looking at ease from pic to pic and discovering some major issue we didn't see live. :-) First (now the first photo), I'd crop heavy, losing the cut stems from the flowers and anything above her head. I'd lose the end of the veil and probably some of the back of her arm. Second (yes, the second photo), I'd probably lose the sidekicks, lots of floor and ceiling - or flip the camera for start. Like very much the way they tower above anyone else, but the floor disrupts that feeling. Third - not so easy to improve, since I also like the idea. Longer lens from a slightly greater distance, maybe? Would it be possible?? Fourth, very close to perfect (I like the idea too), maybe if he would be either holding her hand or offering his hand to her?? Fifth, the one with the green hose... crop it out, not because it is that awful, but because the moment the bride and groom kiss everything else fades away... or at least should. ;-) John, much better than my first wedding photos, not as good as your next... and not a worry since the bride smiled.

RE: Trading resolution for depth of field
you are trying to define some sort of absolute DOF which really doesnt exist unless you consider a certain COC as perfect.

DOF is relative sharpness of foreground and background objects in an image compared to the objects in the plane of focus. ( just my working terminology FWIW). So, if a certain object in the foreground is half as sharp (or twice as blurred) as an object in the plane of focus, is it within the DOF? What if it's a third as sharp? A quarter? Where do you draw the line? To define the DOF, you need a concept of acceptable sharpness or acceptable circle of confusion. These criteria typically arise from assumptions about the final print (film size, print size, viewing distance...). In our previous discussion, I provided a number of reputable citations discussing the origin of these criteria.

RE: Trading resolution for depth of field
Sir, MY burden of proof is no greater than yours. If you cant provide any reliable proof that my contention is not true, then your word is no better than mine. I dont need any more proof to support my contention than you need to support yours. This is very simple. DOF is all about magnfication and f-stop. I did supply the formula, relative DOF = F-stop number/MAGNIFICATION. INCREASING F-STOP NUMBER OR DECREASING IMAGE MAGINIFICATION increases the image relative DOF. Conversely, DECREASING THE F-STOP NUMBER OR INCREASING THE MAGNIFICATION decreases the image relative DOF. If you dont believe me, do some experiments. I have, its called about 35 years of practical experience to back up what I have read in theory. This isn't my theory, this is the correct theory that I have read and found to be true over the years.

But your claims regarding relative DOF are only valid if the image format (film size, crop factor, whatever you want to call it) is constant. A change in format leads to a change in allowable CoC, which you're dropping on the floor. If you dispute that the allowable CoC is different for different formats, then you are the one who is claiming there's an absolute DOF. === NO NO NO NO, My post is ALL INCLUSIVE. The only thing that affects (increases or decreases) the image DOF is : (the image magnification in-camera) (f-stop used). Format, crop factors, COC, print size, etc, blah blah blah have ZERO effect on DOF. That is the common myth I am trying to dispell. Its all about image magnification and f-stop and THATS IT. Changing the format, film size, COC means nothing..ONLY changes to the image magnification and f-stop change the DOF. You seem very certain about this, but you won't provide us with any objective criteria, such as a formula, by which the people who disagree with you can come to any conclusion. Why not? Why don't you provide us with some evidence, then we'll shut up about it? Give us a depth of field formula in which all the terms are constant, except for image magnification in camera and f-stop, and in which viewing distance and coc have ZERO effect. Go on, be a sport.

RE: Trading resolution for depth of field
sharpness has to be defined to define a particular DOF. But when you want to increase or decrease DOF, the whole sharpness/COC thing washes out, only camera f-stops and camera image magnification changes get you there. Im not buying into the argument that if you make anything tiny enough the image DOF is increased or if you make it the size of a billboard the DOF is reduced. Its not, the definition I have been using since the beginnning of thread is that image DOF is all relative, not absolute, and its the relative sharpness of the out of focus planes that can only be changed with mag/fstop. Print size doesnt affect that.
