Master 5557    , California |  Subject: RE: COJ photo class/Q&A threadthere's a relationship between F-stop/shutter speed/ISO.. Its called the photo triangle. this is one of the most important things to remember. (i learning it daily) f-stop is allowable light (smaller the number the more light, bigger the number lessens the amount of light) ISO is the image sensitivity... (the higher the number the noisy the picture becomes) shutter speed is how fast picture is taken Yep and if you step back and think about how a lens works, mechanically, it's all easier to visualize. Even consider why the high end sports or nature photography lenses are so expensive? You usually need telephoto capability to get close to the action. And you need high shutter speed to capture fast action. But at those speeds, to get enough light you want a wide aperture (try finding a 2.8 f-stop lens at 300mm or higher = $$). This is a very large lens that requires a lot of mechanical precision. |

Champion 4835  Eat Cheese or Die | Subject: RE: COJ photo class/Q&A thread Leegoocrap - 2010-10-29 6:13 AM The real test of a photographer's mettle is to take a good camera out of the equation. One of my Professors had us do our entire course on a kodak polaroid. That's when a person has to get creative to get a good shot... Everybody shoots good pics on a canon SLR with 30x zoom and 6k megapixels  with lens flare and dynamic lighting already filtered I learned this in high school when my buddies and I aspired to be the next TGR http://www.tetongravity.com/default.aspx We shot a lot of skiing video, and it was all crap. We found an old super8 camera at salvation army, bought a roll of film using change dug out of the seats of my car and every almost every single second of film we took with that camera is the best work we ever did. Every shot was planned. We were careful with lighting and exposure and didn't waste any film unless it was going to look good. Maybe I should go back to shooting on film? |

Member 39 FL Panhandle | Subject: RE: COJ photo class/Q&A thread A couple months ago on here I was asking a few questions about taking pictures & it was recomendedd that I read "Understanding Exposure by Bryan Peterson". I had no about shutter speed, aperture, ISO, ect. before reading that book. Now we have a Canon T2i, a few lenses (not kit lens), & shoot in manual mode a majority of the time & take some half way decent pictures. There is still a ton to learn, but that book was a great place to start. newbz, thanks for taking the time to do this for all of us! |

I think a good topic would be "work flow"... i finally got a system that works. now i how to get better with photo editing.. i have lightroom.. Newbz do you use lightroom? whats your preferred software.. |

Veteran 276 Holden, Ma | Subject: RE: COJ photo class/Q&A thread newbz - 2010-10-29 7:18 AM My thoughts would be 1: what are you looking to shoot with it? that would be the real selling point for me on one or the other lens wise. Personally i need the length before the speed, so i shoot wit ha 70-300mm Nikon G series, pretty affordable (you can find them for 130 or so if you really look around for good used ones), and is the equivalent of 420mm with the digital conversion length. Plenty sharp enough for everything i shoot (all my recent sports photos have been shot with this). I guess with any long distance lens it will be for nature shots wildlife and also for shooting sporting events. I will take a look for the G series lens, although I am a little concerned buying a use lens. |

Champion 7233 | Subject: RE: COJ photo class/Q&A thread Tynan, if you look used, go through somewhere like KEH camera. They have a very very good rating system for all of their used items and have been very good to work with so far (i've bought 8 used lenses from them as well as a number of bodies) |

Veteran 276 Holden, Ma | Subject: RE: COJ photo class/Q&A thread 70-300 F4.5-5.6 G for $465 or 70-300 F4-5.6 D ED for $126. What will I be getting out of that extra 300? Pretty good prices on the site, thanks for sharing. |

Champion 7233 | Subject: RE: COJ photo class/Q&A thread Main diff (if i'm remembering correctly), The G series has lost the Aperture ring on the body, is lighter, a few of the ED lenses had a dew distortion issues at longer ranges (not sure if this was in all of them though), As i'm understanding now the G series (at least in this lens) is replacing teh ED lens. if you have an older camera you'd want teh ED but with newer the ED is not needed. The G series can also be found like new for 130 or thereabouts (that's what i've paid for my last two and this is the lens i use for all my telephoto shooting right now). |

Veteran 276 Holden, Ma | Subject: RE: COJ photo class/Q&A thread Really? I think the G that I was looking at is LN for the 400 price on that site. I wonder how someone can sell that for that much less. I would grab that in a second. I will keep my eyes open. |

Veteran 276 Holden, Ma | Subject: RE: COJ photo class/Q&A thread What if we try to learn a new technique each week? Such as moving water with a long exposure to get that whispy smokey look. Teach exposure, shutter speed etc. Depending on time of day it can be tricky to keep the shutter open due to it being bright out. I try to go with a smaller aperture higher number F stop( Smaller hole to let in less light). I then may use the + - exposure setting to under expose the image. I also put the ISO or film/image sensitivity to 100. The lower the number the less sensitive to light. If during the middle of day I will use around 1 second exposure to get the whispy water but play around with it. Also a tripod is needed. I am just learning so if I am off let me know. Also I learned from a thread here last week, turn off Vibration Reduction on the lens and use manual focus. Edited by Tynan19 2010-11-02 8:42 AM |

Champion 7233 | Subject: RE: COJ photo class/Q&A thread Ok, this actually sounds like a good idea (tynan). So here is what i'll do right now. I'll put a post on the blog. we'll work through shutter speed and aperture first (i'm going to leave ISO projects out of it as almost all of the newer cameras are reducing the diff between high and low a LOT more than the older ones/film). I'll put up some example photos and then we can hash out some project photos on here and talk about them/provide advice/crits etc. That should provide some very basic projects/info that you can take ANY direction you want to. |

Expert 997 North Central WV | Subject: RE: COJ photo class/Q&A thread A quick question - I mostly use the camera on full auto (Canon Rebel XTi - with the lens it came with EF-S 18-55mm). My photos are never as sharp/crisp as others. I am 100% sure I am using the autofocus correctly. Is it the resizing process, the quality of the lens or something else that is most likely responsible? My eyesight isn't good enough to manually focus. |

Also I learned from a thread here last week, turn off Vibration Reduction on the lens and use manual focus. No tripod is needed if you are creative. My best low light/long exposure shots have all been taken with the camera sitting on the ground, rocks, railings or other steady objects. Sometimes it can be difficult to line up the shot, but since I don't carry a tripod with me everywhere I end up improvising a lot. Not being picky, just pointing out that people don't have to go out and spend money just to try out low light or long exposure shots. Now, off to Chicago for two nights. I think I'll be mountain biking tonight and shooting tomorrow night. |

My eyesight isn't good enough to manually focus. could be the lens (dont know canons lenses well), could be due to a low shutter speed and camera shake, could be camera settins (less likely), or what you are doing in post processing (more likely if the lens is good). |

Veteran 276 Holden, Ma | Subject: RE: COJ photo class/Q&A thread Dave, I improvise a lot as well on the stable objects. I recently submitted some photos to a fishing magazine and the editor was impressed. He asked what I had used for a tripod as it was such a far off place to lug anything out to.. I said I used my eel bag ( Salt water fishing at night for striped bass we use eels ) I had to place my camera on the soft sided cooler I use for eels on the rocks next to the ocean. Pic came out great. However shooting in a stream or river I much prefer a tripod over placing my camera on a rock or shoreline object. |
