How many exposures of 1 second or less can I get in two minutes

Question

I'll have two minutes to photograph the Great American Eclipse.  I'll be using BYE and a Canon 60Da.  I just set up a series of 8 exposures 1 each of  1 second, .5 seconds, 1/8 second, 1/15 second, 1/60 second, 1/250 second, 1/1000 second and 1/4000 second.  With LENR set to 0, the time from shoot No.1 to save No. 8 was 2:15.  With LENR set to 1 the time was 2:30.  Is there any way I can improve on this with BYE.

You can set the Camera to "Save to Camera Only", so there is no Download.  (But, this may require one of the Pre-Release Builds of BYE v3.1.12 - I believe Guylain has found a Fix for the 60D's issue with "Save To Camera" recently).

You will DEFINITELY NOT need LENR (Long Exposure Noise Reduction - which pauses Camera to take a Dark of equal duration to most recent Exposure) while shooting the Eclipse.

Yes, latest release of 3.1.12.RC9 should allow save to camera only.  This should give your about 15 images per minute if you have a fast card.

I downloaded 3.1.12.RC9 and it won't send images to my 60Da memory if the Camera setting is set on the imaging window.  The camera will save images to the card if I disconnect it from the PC.

If I save to camera+PC the light on the back right of the 60Da lights but it doesn't save an image on the camera card.  It doesn't light when I save to camera or PC. 

The card is a 32MB Sandisk SDHC I 10 with 30Mb/s transfer rate.  I am connecting to Canon215.

I have found that using a fast memory card can speed up imaging when saving to the camera's memory card. I am using a Samsumg EVO Plus 100 Mb/sec memory card (64 GB for $30 US). I will capture 56 exposures during totality, but sadly not with BYE. That is about 1.4 seconds + the exposure time for a range of exposures from 1/4000th second to 5 seconds.

Good luck to all eclipsers! Perhaps I will see some of you in Casper, WY. I will be at the ALCON convention, while staying with some of my local club members at the Ramkota Hotel.

With BYE and this 32MB Sandisk SDHC I 10 with 30Mb/s transfer rate I am getting 14 exposures saved in 1minute 30 seconds.  Exposure range is 2 ea. of from .5 to 1/4000.  What were you getting with your 100Mb/s card with BYE, and were you using 3.1.12?  3.1.12 patches direct to camera saves.

I created an exposure plan in BYE 3.1.12 and ran it against my T5i with the 100 MB/sec memory card. I created a 12 exposure plan with shutter speeds from .5 seconds down to 1/4000th saving only RAW images to the card. It took 47 seconds to run to completion.

This seems much faster than your 14 exposures in 90 seconds. Both my T5i and your 60Da have 18 MP sensors so the amount of data transferred per picture should be about the same, but the T5i has the DIGIC V processor and the 60Da has the DIGIC IV processor so the 60Da may be a bit slower. Still, given the rarity of a solar eclipse it might be worth the $$$ to buy a faster memory card.

12 exposures at 47 seconds w/ 100Mb/s card vs 14 exposures @ 90 seconds w/ 30MB/s sounds like the difference could just be the write speed of the card.  Just curious, what are you using to get your 1.4 second writes?

Is the feature "Save to Camera Only" in the EOS Utility?  I have a Canon 600D and I don't see where it is.   I updated to v3.1.13 today and tried a new run of images.  I'm only getting 18 one second RAW images into my PC in the 2' 10s I'll have for totality.  Faster 300MB/s SD cards coming., but is that the final answer?  Is Eclipse Orchestrator THAT much faster?  Thank you!

No, the Save To entry is in BYE in the Capture Plan Center of the Imaging screen. It is discussed in the User Guide which is installed along with BYE. Click on the "?" at the right end of the BYE title bar.

Your performance will be much improved if you do not download your image to the PC. I captured 42 1 second RAW images in 130 seconds with BYE 3.1.13 and my T5i with a 100 MB/s memory card.

That performance is only a bit slower than Eclipse Orchestrator. However, the author of EO recommends using a serial shutter cable for maximum performance. I do not have a serial shutter cable and decided that I did not need one. I am also skeptical that the serial shutter cable will be faster. My exposure plan during totality has 56 images, but my totality is somewhat longer than 130 seconds. It is more like 161 seconds. The exposure durations vary from 1/4000 to 5 seconds.

I hope this helps.

  I agree with Rick on the serial cable.

  I don't have an active computer now that has a serial port.  All of my serial interfaces come into the computer at a USB port.  This leads me to believe if there is a choke point in USB you are still with USB Speed.  Several web pages suggest using a serial port though.

Rick, 

Yes, your answer about "Save To" being in the Capture Plan Center was exactly what I was looking for.  Can't tell you how many times I've breezed right by that little nugget without changing it.  Completely forgot it was there!  Thank you.  I tested this pm and got 35 shots in my 130 seconds with my older C10 SDHC card.  I have new U4, 300MB/s cards here tomorrow.  Hoping to get get up into the 50's like you for lots of bracketing.  I am shooting as many images as I can push through at 1/4000, 1/2000, 1/500, 1/125, 1/4, 1/2, 1, 2, 4 seconds.  Thanks for your clear explanations!

Hi Falconr

 

  I suspect that the 300mb/s card is UHS-II if it is a SD Card.  You may not get the 300 mb/s write you are expecting.  I don't know what speed it will revert to when used in a UHS-I slot but it will be slower than 300 mb/s.  I haven't looked at recent cameras released but until last year none had incorporated the UHS-II.
