Description: A shot of the underside of my first ever accelerator card, which was an early Apollo 1240 (the ROM appears to be a socketed EPROM in contrast to later revisions). Going from a basic 2MB chip RAM A1200 to one with a 25MHz 68040 with a then whopping 8MB of 60ns RAM was quite something, especially back in 1995 (96?) - whenever it was that I got it :-) Given I was a student at the time, I remember eating beans for a month after buying it :lol: Unfortunately, this particular card is pretty knackered, as our erstwhile Vincent can probably attest to ;-) Every now and again I get it going and it powers the 1200D that sits over my desk.

Indeed, bring it on, lets see what you can do :-) |

It must have somthing to do with the point of focus, had it been the very front of the keyboard, then you would have seen a falloff of DOF. See the little box in the centre of your cameras screen, thats your focus point. Most cameras have an option for "closest subject priority" or something similar, hence it will AF on the closest subject. Another thing to consider is that there are two types of macro modes on digital p&s cameras, optical and digital. Optical involves moving the lens element further from the sensor, you can focus closer at a cost of being able to focus to infinity. Digital is a form of on the fly cropping that gives you the illusion that you are focusing closer. |

| December 15, 2006, 07:12:38 PM Right then... Macro time it is. I got a new Digicam the other day... lets see what it can do! |

| December 15, 2006, 05:44:27 PM "...Ah, well, I was talking about the other shot that doesn't look macro but was taken in macro mode regardless..." -------------------------------------------------- Ja, I also am thinking about what happened there :shrug: |
| lorddef Posts:1146 | December 15, 2006, 02:38:01 PM @Karlos Yeah I remember, I was just saying, I remember. ;-) |
| Karlos Posts:16879 | December 15, 2006, 11:08:09 AM @adz Ah, well, I was talking about the other shot that doesn't look macro but was taken in macro mode regardless ;-) |
| Karlos Posts:16879 | December 15, 2006, 11:07:01 AM @lorddef I seem to recall Vincent had first dibs (He'd PM'd me about it before you did at least) but he couldnt get it working for more than 5 minutes. For that matter, neither can I, most of the time. The ROM is utterly shagged and even though I retouched a whole cluster of fractured solder joins, this card is an ex accelerator... |

| December 15, 2006, 07:24:51 AM Yep, he demonstrated a good thing here. There is no question of that. 8-) |

In this shot, you have demomstrated that you have some control over the DOF, as you can see, only the centre band of the image is in focus, which is a good thing :-) |
| lorddef Posts:1146 | December 14, 2006, 08:21:45 PM I remember you offering me that card before it went off to Vincent. |
| Karlos Posts:16879 | December 14, 2006, 01:40:41 PM So, I'm still no clearer. Is it a good or a bad thing that my camera can make macro shots with such a wide DOF? |
| adz Posts:2961
| December 13, 2006, 09:18:06 PM DOF is all relative to the distance from your subject, the closer you get, the narrower the DOF gets, hence you have to stop down more to get anything surrounding your subject in focus. Most of the macro shots in my gallery were taken at F/32, a little pin prick of light, hence the DOF is quit large, but still not large enough to bring the whole frame into focus. I'd have to stop down to F/64 or something crazy like that, shame my lens can't do it. |

| December 13, 2006, 06:49:58 PM Oh. Well then it is a mystery of technology and circumstances. No matter, you have the macro thing down now. |
| Karlos Posts:16879 | December 13, 2006, 12:42:03 PM @X-Ray It was in macro mode (at least according to the display), but the lens and sensor were above the keyboard so it just focused as far into the distance as it could? |

| December 13, 2006, 10:40:36 AM An inset is cool, one of mine has an inset. But I would have made the macro part the main feature and the overview the inset. Looking at this image makes me wonder if that other picture with the penny on the monitor was really done in macro mode. Because this picture shows what I expected: items in front of and behind the subject out of focus. But on that other picture you have a greater d.o.f (even the keys on the keyboard are in focus, and much of the Amiga keyboard too). |
| Karlos Posts:16879 | December 13, 2006, 12:13:02 AM Cheers :-D I only just figured out how to set it to take the image as TIFF rather than saving it as JPEG, which produced a much crisper source image (naturally)... I guess this image doesn't count though, because I modified it by adding a bit of text and putting an inset clip at the original image resolution ;-) |

| December 12, 2006, 11:11:09 PM Great shot dude, perfect pic for one to describe the concept of DOF. 8/10 from me :-) |
| Karlos Posts:16879 | December 12, 2006, 08:23:11 PM I'm guessing the inner pins are for the 060... |
