Canon General / Re: Battery Overheat

Popular power tool batteries/chargers can also cause a fire.

Those of you that leave cordless tool batteries and chargers on and unattended are asking for trouble.

I know one person that almost lost their home and another started smoldering on a jobsite- which set off the alarms and the FD showed up. Not the first go around for that FD and that particular brand of charger/batteries.

Consumer grade chargers are manufactured to a cost/profit point, not necessarily quality.

Site Information / Re: Small or Large Thumbnails - Poll

I prefer the larger thumbnails.

I am also one of the apparently few people that have "slow" internet.

It would be nice if there was a picture size (bytes) limit if the preview window is small.

I really do not see the need to upload images that are megabytes in size. I can use free software that makes web-friendly 800x533 images that are less than 300kb at the best quality setting with little apparent loss of detail. Setting the quality at 80% frequently makes the file size ~125kb.

Clicking on a 200x200 preview and viewing a 3mb attachment isn't happening here.

Attachments do not always work well on mobile devices, clicking on those 3mb files uses mobile data, too. 

+2 on removing the image from a reply quote.

Lenses / Re: Help deciding on a macro lens
« on: August 04, 2014, 06:02:03 PM »
I'd be grateful for any advice and your experiences with different macro lenses.

While it is possible to do "macro" and use autofocus, changing the focus changes the magnification. As Neuro explained, the only reliable way to maintain 1:1 (or max magnification) is to set the lens to the maximum magnification and then move the camera and leave the focus adjustment on the lens alone.

Purists will call anything less than 1:1 "close-up" rather than macro.

I have tried manual focus and then switch to live view to confirm (tripod in use), and I have been off. Maybe more practice will help.

A 180mm macro lens will give you more working distance to the subject than a 100mm macro at minimum focus/max magnification. This may be important to you. I happen to like the 150mm Sigma macro.

As magnification goes up, depth of field goes down. Very little of a macro shot at 1:1 and at f2.8 will be in focus, unless the object is flat and in the same plane as the camera sensor.

Given the performance of current digital cameras, I'm not sure if the difference between f2.8 and f2.0 is massively importatnt from a lighting perspective. Bokeh and depth of field, sure.

The Canon 100L macro also has the fancy IS stuff- nice to have when you need it.

There are many threads/comments about the Canon 90mm TSE being *the* product photography lens. Maybe there is a reason? It also takes teleconverters for an easy 126mm.

Another Nikon 105 DC stuck on a 1DX shot...

Pretty sure I had an extension tube in there too.

It says "any Thing shot with the 1DX;D

Whew :)

Does using a Nikon lens on a 1DX count?


Software & Accessories / Re: Lightroom vs. Capture One
« on: July 22, 2014, 04:40:47 PM »
I prefer the Capture 1 output over Lightroom for flower pictures.

I'm certainly no pro with post processing stuff, but the C1 looks nicer right out of the box. This doesn't mean that you can't get there with Lightroom.

Edited to add: From a hobbyist point of view, DPP sure seems to do a damn fine job at processing Canon images. If the image is good/close out of the camera, just a couple of quick clicks does the trick. As much as I may hate to admit it, the "auto" and "auto +" do a damn fine job of recovering underexposed images. I haven't tried 4.0 yet.

DPP is free- added bonus.

Notice how the frames march closer as focus gets closer as though the lens zoomed.
I actually think it did zoom but I'm clueless how and/or why.

As you change the focus in a macro lens, the magnification changes.

You can see it if you turn off AF, prefocus at the "further" range, move in manually until the object is in focus, then repeat closer in. The object will become larger in the viewfinder.

The magnification ratios are different, and that is printed on the focus scale (1.5:1, 1.2:1,1:1- or however they are laid out).

I believe the technical term is focus breathing- could be wrong.

The only way to keep the magnification the same and change the focus point is to preset your focus, turn off AF and move the camera in/out to focus the desired point. Best way to move the camera is with a set of gear driven (manual or motorized) focus rails. Any precision or repeatability without a gear driven system is damn near impossible.

I have a set of rails and have messed with an MPE-65, and I can see the focus change as the setup is moved on the rails. It doesn't take much movement. Apparent magnification (object size) does not change. Moving the tripod in and out proved to be useless.

I found it quite interesting, but it is very time consuming.

I suspect that the apps using focus stacking vs rail movement are stretching/shrinking the sharp parts of the image to blend it together for the final result with assumed quality loss (small image is expanded and large final image is shrunk). I would assume it picks somewhere in the middle as a starting point for final image size/scale.

There is a lot of skill in a good focus stacked image.

Why, thank you!  Your shot is certainly a pleasure to see.  What is your favorite genus?

I'm not a gardener or botanist- just like to take pictures.

I suppose that knowing what they are could help sometimes :)

6D + Sigma 180mm f/2.8.  Blossom is 7mm across.

I've always liked those.

It's obviously an EOS M with a foam surround to make it look bigger....

Windows 8 is a dual-mode operating system. On a desktop, if you prefer, you can still use the classic windows desktop all the time. You can boot to it and use it pretty much exclusively. The only explicit change is the removal of the start menu for the start screen. But the start screen works 100% perfectly well with mouse and keyboard (and, for that matter, it also works with a TV remote when using a Media Center remote control). There is absolutely NOTHING about Windows 8 that makes it difficult to use on the desktop with a kb/mouse. I've been doing it since day one. This is Microsoft's greatest mistake...not properly educating their customers as to what their OS can do. Windows 8 is Windows 7, with more. That's it. There hasn't been a loss of compatibility.

I'm pounding away on a keyboard right now, in Chrome, on the desktop, on a standard computer with no touch screen...in Windows 8.1. Touch is not a requirement in Windows 8. It's an option.

Well, I'll have to look into it more deeply then.

I understand that touch is not a requirement, but how to get there (1) isn't clear and (2) is filled with misinformation.
