Technical Support / Re: Removing Vignetting On 3rd Party Lenses
« on: September 11, 2012, 10:04:12 AM »
There are sliders for all of those, and for white balance there is an eyedropper tool which you can use to select a white or grey reference and it'll figure out the WB and temp for you.  Also there are auto white balance and auto tone tools, but I haven't played with those.  I regard LR as essential.

Jim

Yes, my main issue with LR has been the white balance and look of the pictures is never as nice looking for me as DPP. I downloaded a trial of LR after DPP crashed on me that time though and noticed if I changed some tab from 2010 to 2012 or something like that the colors and white balance were much closer to what I get in DPP so I guess I'll have to decide if it's worth switching over or not. I think I've gotten a little too accustomed to DPP but if it ends up crashing on me again then I might make the switch.

@Brian, I see that you have a 50 f1.8. I also have one and have used it with the Kenko extension tubes with good results. If have the $ I would say just buy the set of tubes from Kenko (about $200). If you are going to rent I would recommend going with a 12mm tube if you are shooting wedding ring macros. Hope this helps. Good luck.

Thanks everyone. I'm renting 40 2.8 again and the Kenko extension tubes. We'll see how we go. @Mt Spokane, I have contemplated using a 1.4 TC or close up lens with the 70-200 IS II but decided to go this way based on some back and forth with Roger over at Lensrentals.

You can do this in light room in bulk, look for some tutorials to show you

I agree on LR4; It can get a bit slow when you have a lot of brushstrokes but for vignetting it is absolute dynamite.  I'll run one through if you want to put up a CR2.

Jim
Crap. I was wondering if that was going to be the answer. Currently I don't have the money for LR. I was pretty upset with DPP a few weeks ago when it crashed on me after an hours worth of work. I'm assuming this means I would just use lightroom for everything, white balance, exposure and color correction as well? Is it in any way automated or a slider or what?

Lighting / Re: Direct Flash - How to make it useful?
« on: September 10, 2012, 05:27:37 PM »
I can never get good direct flash, how do you get decent images like the one below.

I like off-camera and very competent in that, but direct flash I never could quite grasp it.

Tips?

Without seeing the EXIF data and what sort of like it was taken in you don't know. My guess just looking at it is that's not a full on flash for the light source but more for the dot in the eye and removing some shadows. That's just my guess though.

So I use Digital Photo Professional for editing my pictures. I normally don't have to mess with vignetting at all due to most of my lenses either being Canon or they have low enough vignetting that I don't notice it. I just did a wedding with the Sigma 85 1.4 though and when wide open it has a fairly noticeable amount of vignetting that I'd like to try and remove. Is there anyway to do this inside of DPP? If not, what's the best way to go about trying to fix this in something like Photoshop or something else in bulk? Thanks.

Yeah I rented one this past weekend and it did seem to focus fairly close. Although the 35 2.0 I have is capable of focusing even closer. I'm looking for higher magnification than can be offered by the lens itself. I don't currently have any extension tubes or else I would of done some experimenting with that while I had the lens so sounds like I'm going to try out the 40 again and this time rent some extension tubes as well. Pretty much as expensive as renting a macro this time around but long term if I decide to buy it'll be cheaper and work on all my lenses.

The 40/2.8 will give a higher max mag due to the higher native mag and shorter focal length.

Sorry, no idea on optical difference though, but I expect the 40/2.8 would give better results.
Thanks, well if I'm renting the 40 and I have the 50, if I have the time I might try taking a couple of shots on both and see which is better. Thanks Neuro.

The 40/2.8 does great with a 25mm tube, mag is ~0.8x.  IIRC, working distance is ~6-10", can't check exactly as I've loaned out my 25mm tube.
Thanks Neuro I'm assuming the 40 would work much better than the 50 1.8 that I also have stopped down?

The 70-200 2.8IS ii is a great option. Expensive and heavy but a really awesome lens. One other option that I haven't seen listed in the postings so far is the Sigma 85 1.4. I just rented this for a wedding this weekend and was really happy with it.

Lenses / 40 2.8 with extension tubes
« on: September 10, 2012, 10:14:00 AM »
I was just wondering if anybody has tried out the 40 2.8 with extension tubes. Given its very small design, I would think this would give a greater minimum working distance since even with the extension tubes it wouldn't stick out as far as some other lenses.

I'm shooting a wedding in a couple weeks and am not planning to rent a macro for it. I just shot a wedding on Saturday and only used the 100 IS L for a few shots of the ring so I can't really justify renting a macro just for that little. I have the 24 105 and am renting the tamron 24 70 as well in case anybody has any input on if those would work better with extension tubes (I would think not). I also have been wanting to try out the canon 35 1.4 and own the canon 35 2.0 if anybody has tried it on those as well. Thanks.

"There's a separate plug for the remote shutter operation as well.  Here's the rub on that one though, you have to have it mounted on a hotshoe for it to work, it's a little annoying.  But, no biggie.  I only use them for manual flash work."

What do you mean it has to be on the hotshoe? I just did a wedding last night with only the shutter release cable plugged in and the transceiver hanging from the cord. The other one was in my hand. Worked fine.

Software & Accessories / Re: DPP for MAC too slow?
« on: September 07, 2012, 06:07:37 PM »
After doing a lot of tests using both the Mac and PC versions, I think I have managed to identify the cause of the issue. On the MAC version DPP has a problem handling folders with over around 400 images in them. It seems that there is a memory management issue. On the PC version, it does not appear to be a problem.
Very interesting. I run on a Mac as well and I tend to run into a lot out of memory issues when I have a big folder of pictures. Is it exactly 400 or there abouts? I might have to start splitting up things into more folders but if it helps with these issues then that's not a bad trade off.

Actually I think it's not pass through but more the trigger acting as an ste2 and the flash while attached is receiving signals like it would if it was wireless. I've definitely looked into those and after seeing the limits of this device will look into more. The main thing is its a brand new product and doesn't have a USB upgrade port so I'm tempted to wait some. I discovered a way to make the required change without soldering but I may end up soldering at least one spot.

Have you tried <Tools> then <Preferences> and in the General Settings tab (near the bottom of the panel) where it says "Default value of output resolution" [dpi 1-60000] and then changing this value. All you really need is 150 dpi or 72 dpi for screen resolution. My default on PC (similar spec to yours i7 3.4 GHz, 16Gb RAM, Nvidia GTX570 etc) is automatically set to 350 dpi for thumbnails.

Try playing with this setting and see if it speeds things up.
I don't think that really makes a difference as it's still the same number of pictures. I think that's more for printing settings.

Software & Accessories / Yongnuo RF-603 Limitations
« on: September 01, 2012, 11:29:22 PM »
So I just got my Yongnuo RF-603 triggers. They're not bad for the price but I realized a couple things now that I own it that I didn't realize before hand. I think I still would of gotten it but it does show that it designed to be used a specific way and has some freedom limitations. Anyways, the first thing is it took me forever to get it working. I put batteries in both triggers but when I would push the button it wouldn't send a signal to the other trigger. I tried different channels and batteries thinking those were the issue. I finally put the trigger on top of the camera and suddenly everything worked. I googled around and discovered this is a limitation of this model is that the transmitter has to be on the hot shoe on a Canon camera to work. The main thing that stinks about this is it means I can't use an ettl flash on the hotshoe at the same time I'm using this trigger :( I tested to see if the ETTL passed through but it doesn't (not that I'd really to do that since there's no locking base on the triggers). The PC port is an output only so you can't send a signal to the trigger through a camera's PC Sync port. There's stuff online about putting in a resistor inside the unit to trick into being a transmitter always. I don't completely understand what they're doing but my question is couldn't this be done outside the unit as well? So have like a hot shoe that you put the trigger on that has that resistor built into the stand? Then you could just remove the stand when you didn't want it to be transmitter and then you could put a pc sync input on it as well so you could activate the trigger from the pc sync out port.

Another limitation I found and this is more specific to my setup. But I would like to have a setup where when I take a picture with my primary camera, the secondary camera takes a picture as well. I can make this work if I plug the remote shutter release into both cameras and their respective trigger but if I use the cameras built in button to take a picture then the other camera won't take a picture which means I have a very awkward setup to have to use the button built into the trigger since once again the 2.5mm output for remote release is output only not input. I brought this up in another thread and thought I'd bring it up here as well that I'm wondering what would prevent you from using the PC sync port to trigger the other camera to take a picture. I did some testing and the voltage the trigger is sending out is maybe a volt if that if my meter is working correctly. The camera itself is sending a higher voltage than that for the remote release trigger so I don't why that wouldn't work but then again I'm little eerie of trying it out with off chance it would take out a circuit board in the camera. The safest option would be to use a relay or something similar that upon getting the input voltage it completes the remote release circuit. By doing this, whenever I take a picture with the main camera it will send a signal to the second camera to take a picture as well which is what I want.

Any thoughts anybody?
