SO! I took some shots last night when my batteries were all juiced up. Can I tell you at how sleek the shutter action is, how I marvel at the sound of a taken shot, how amazing I feel looking through the viewfinder? It is like coming home. It feels right to hold it. It feels like I regained something with the few images I took last evening.
Can I tell you how many new settings I have to learn?!? Good god. I figured out how to change the WB and ISO without using the interactive menus. I have a vague notion how to change the aperture and shutter speeds, depending on program setting, without the menu. But lord, I can't get it in my skull exactly what they do. I mean, I've read about f-stop, aperture, shutter speeds etc and know what they do mechanically but these sites don't really suggest what this does to your images.
So... large f numbers mean a smaller opening which lets less light through to the exposure receptor. The smaller the opening the longer the depth of field, meaning objects appear in focus further away from the camera than at larger apertures. This doesn't really make much sense to me but I believe it has to do with how the light bends through the smaller aperture. I think what aperture comes down to practically is the smaller the aperture (larger f number) means a deeper image. Depending on how important the background is, I should decrease the aperture (increase the f number) accordingly. I think... ultimately there's more to it creatively but I'm just trying to get it straight in my head for the moment.
Now.. shutter speed is pretty easy on it's own. More exposure at slower speeds, less at faster. When motion is involved, faster shutter speeds will result in less blur in the picture. Also, faster speeds are better for images that will be blown up for similar reasons.
Now there is some linkage between shutter speeds and aperture that is still mud in my brain. Clearly, the amount of light getting to the exposure plate is important but understanding the effects of aperture plus shutter speed is probably less quantifiable and must be qualitative. Meaning, I'll understand better as I play with it. Were I to postulate, I think i should avoid longer shutter speeds and lower f numbers (larger aperture). This would result in washed out images - too much light getting in. Longer shutter speeds at higher f numbers would be better for macro shots, allowing more exposure (and increased detail capturing?) and greater clarity/depth of field for night shots. I think... maybe... So, in general a medium sized aperture and a faster shutter speed is more useful for regular shooting, with minor adjustments for lighting - less lighting means a slower shutter unless I don't want as much background clarity, in which case I open the aperture.
Ok, that makes logical sense.... If any of you could explain it better in an end-result fashion, I'm all eyes.
