I use whatever aperture I need to make my composition work. Sometimes that's wide open at 1.4 and sometimes that is at f16. Get good lenses and then just focus on your image without worrying about the technicalities.

Mark_Cohran Cream of the Crop ![]() More info | Jan 01, 2017 21:46 | #20 I've seen situations where the pursuit of sharpness was detrimental to the overall image. Sharp can be good, but it's not the only characteristic that determines the quality of an image. That said, I know my lenses well enough to know where they're sharpest if I need it. As Photoguy said, it's typically 2-3 stops down from full open. Shoot with a lens enough and you'll soon find it's sweet spot. Mark

Jan 04, 2017 11:08 | #22 Thank you for all the responses. I just want to be sure its clear that I do understand that this is just one of many considerations that have to be balanced to get a fine image. At this point, I think its safe to say that I've reached a solid intermediate level with a pretty decent understanding of most of the principle concepts involved. Of course, there's always room for improvement, and the goal I've set this year is to really deepen my technical expertise from the shoot side of the equation (post-processing will likely be next year's deep dive). It seemed logical to me to start with sharpness, focus, and DOF - which leads to this discussion. I should also mention that the more esoteric items (such as composition) are things that I always work on regardless of the year's focus area as one needs both the technical and the artistic.

(5 edits in all) | Jan 04, 2017 11:56 | #24 Photography is always about a bunch of compromises. Based upon the shooting circumstances, WHICH of the factors to compromise the most will vary.
Digital photography, I believe, has put entirely too much focus on the technical superiority of shots in the average shooter's mind, to the detriment of the quality of the compostion or to the accuracy of exposure...I see all too many grey snow and grey paper photos, not WHITE the way it really is, posted as examples on POTN about some other complaint like focus accuracy!

Wilt Reader's Digest Condensed version of War and Peace [POTN Vol 1] ![]() More info Post edited over 6 years ago by Wilt. (2 edits in all) | There are two aspects about 'technical'...accuracy of exposure vs. pointless abstraction of the technical. Accuracy is 'get it right', but the pointless abstraction is shooting 'only at the sweet spot' aperture or discussions of grain dimension or pixel-to-pixel center distance. Yes, Ansel wanted sharp photos, but he also wanted sufficient DOF for the scene he wanted to capture. And depending upon circumstance, DOF might override ultimate sharpness in one case, and ultimate sharpness might override DOF in another. That is the compromise we make, yet the center of attention for Ansel always has been 'Get the desired Photo in mind!, first and foremost. You need to give me OK to edit your image and repost!

tonylong ...winded ![]() More info | Jan 04, 2017 23:38 | #28 craigat wrote in post #18233238 ![]() Wilt, I totally agree that the technical is often emphasized over the artistic to the point that it becomes a problem. That said, technical expertise is still required - Ansel Adams created amazing images, but he wouldn't be known today if he didn't have sufficient technical expertise to make the print come to life (and even invent some of the technical processes by which the prints were created). Of course the reverse is also true, we're Adams a brilliant technician who knew nothing of composition, we again wouldn't know who he was. The only real way forward is to continually strive to improve in both areas and to work hard at bridging them into one seamless whole. My discussions here tend to focus on the more technical areas because that's where I tend to have the most difficulty. I was originally an artist by trade (classical musician), so my mind is always working on the aesthetics, and that is something I tend to pickup on more naturally. I also know where to look to figure out what and how to do and, most importantly, I recognize that the effort there will always be miles to go no matter how far I travel. The technical however, is an area where mastery can be gained (note I didn't say absolute mastery) with careful study and practice at a quicker rate. To me, at least, it's the low hanging fruit of photography, and the place where, at this point in my development, I will get the most gain from the effort. As you can guess, I do work on the aesthetic as well (otherwise, why bother shooting) and my snow is white ![]() Hey, this dang post brings something up to me, and that is that I have spent a lot of my life playing music!!! I started out learning guitar, then I moved into Blues harmonica, and then, well you name it, sax, violin/fiddle, keyboard/piano/organ, all that jazz! And yeah, it all matters, both hitting the right notes (and really hitting them) and doing it in such a way that really gets across your "vision"!!! Tony

Heh! If you've delved into music, first you have to learn "perfect pitch", I figure that takes maybe 1 1/2 years on a given instrument, then, hey, get together and "jam"!!! Tony
