Allowing the camera to readjust exposure from frame to frame may very well bite you in the hindquarters. Sequences need a constant exposure.

BTW, what is this about the camera being in constant motion ? I must’ve missed something. Constant motion ?


Yes I put it in burst mode and pan across the subject so that each shot is slightly different. F11 helps keep it in focus. Program mode helps keep the exposure right and high ISO makes it so that if I get into a darker scene I can still get a proper exposure.

I know your questions pertained to methodology. However, it seems to me that your client has a pretty flaky idea - I think I'd ask for my money up front!

This is definitely a challenge!

"...you just can't put the camera on continuous and fire away..." That was my thought. Although Continuous would get a lot of images quickly, the client wants them to be in focus, and moving the camera could cause blur. If it were me, I'd concentrate on quality more than speed. Sure, it would take longer, but I wouldn't have to delete half of what I'd taken. Continuous shooting would work, but it would have to be used moderately. This will need a bit of experimenting.

Working outside, the shutter speeds are in the 2000 range so no worries.

I have never tried this but you may be able to use your cameras video mode and then you a software that allows you to do frame capture.


I forgot my other DSLR has video.

Yes that’s true. I should have said it was visible to search engines only.

Interval shooting allows you to set how many shutter releases will automatically be taken, and how long in between shots once you activate it. This will allow you to turn it on and leaf (pun intended) having the camera shoot automatically. The fan will move the leaves gently leaving your background framing the same so it will actually look good. An intervalometer will do the same if your camera does not have interval shooting. What kind of camera are you using? Worth experimenting. You are talking about hours of shooting. I would find a way to automate shooting, cataloguing and processing.

I think just moving constantly will make each shot different. I’m using a Canon EOS1D Mark II

No slightly different framing each time. Even the slightest difference is all that’s needed.

What I’ve been doing so far is checking the exposure as I go and letting off the shutter button if the light changes. I don’t think focus is critical so I’m just firing away. The Program mode seems to favor f10 and f11. So focus is not too bad.

The limited buffer so far is not too bad. I shot 1200 in about half an hour. So far so good.

On Program the exposure changes as you go unless you hold down AEL. This is my thinking but I’m letting off occasionally just in case.

"...I have been given an assignment..." Is this your employer?
If so you will likely lose your copyright to all images done under hire...

Unless you negotiate a "Contract" for this work before accepting the assignment.

"Any suggestions?" fotoman150 you have the cart WAY before the horse here...
Why are you stressing over how to capture images?

My very sincere suggestion is formalize a contract to submit for this work.
Be certain you have the skill and knowledge to achieve all that is enumerate in your contract.

Also clarify the ownership and usage of YOUR imagery...
Specify a time limit... a distribution limit... etc.
If you client walks away from your bid, it may be entirely in your best interest.

A brief look at the caliber of your portfolio leaves me with the impression that you have a good command of your kit. Please do not take on an assignment that you do not have the current expertise to accomplish... This never ends well... https://static.uglyhedgehog.com/upload/2021/2/12/859048-47_4223_8ab3_9030aa8e42e1.jpeg

However if the client is your employer?
Good luck... this is meant in all sincerity..

No not my employer. These are just going to be imbedded in website code so I’m just going to hand them over as is. No PP. He paid half up front.

I don’t think this is beyond my ability. I just have to figure out the best way to go about it. Lots of things to consider but no need to overthink it. Thanks for the compliments. Your posts are always very helpful. Thank you

Here is what I would do, depending on your camera's capabilities.
IF you have interval shooting as an option, I would program it to shoot automatically in continuous focus mode. I would make sure that you have enough light to shoot at a shutter speed of at least 1/800 for the next suggestion, you can also up your ISO to get there. If you need additional light, you will need continuous LED as a flash will be pretty difficult for 5,000 pictures. I would use a small fan to gently blow the leaves so they show some minor movement. The fast shutter speed will freeze the motion but will give you a little different picture each time. I would not use 1/8000 as every shot will be nearly identical and from what I interpret your assignment to be, you want a slight difference between each shot.

If you do not have interval shooting, get an intervalometer for your camera and program that for your shots. Either way, buffer should not be an issue as once this is set up, you will not need to do anything and you can set the time between shots at a second or two to deal with buffering. You definitely need a tripod however. You can move it slightly every 100 pictures or so.

Here is my math. Double check it however.
5000 shots/3600 (#/seconds per hour) = 1.38 shot per second. Add 2 seconds between shots = 10,000 seconds. seconds/3600 = 2.7 hours plus 1 hour for your shots = 3.77 hours total. I think this is right. Please pick this apart. Make sure your card is large enough for 5,000 shots, and your battery will last long enough.

Hope this is helpful.

One question, why do you need 5,000 shots?

So far what I’ve been doing is using a 4 gig card so I can tell how many I’ve shot because he wants just so many shrubs and so many trees etc. I raised the ISO as high as it goes because who cares about noise if they’re not going to be displayed. Shooting in Program mode, high burst auto focus and just pan and fire away.

What is interval shooting?

Contractual issues really wont matter much because these will be throw away images.

I would say shoot in jpg format and select a small image size and basic quality. This will reduce the burden on your buffer and everyone's work flow. Have a couple of memory cards and spare batteries available.

Yes I’ve experimented and with a small jpg setting the buffer has less stress. So far so good.
I fully agree with auto everything settings.

Actually I think the frame rate is irrelevant because although you have 5000 pictures to take you just can't put the camera on continuous and fire away. Do you think you need to do any PP?


No post processing. The idea is to put it in burst and fire away as I move. Each photo will be slightly different. They will not be displayed, only embedded in website code. Visible to google only

As well as continuous shutter release you'll have to keep the shutter speed high since the camera will be moving as you shoot.


Yes I’m outside in the partly cloudy sky. Plenty of light so shutter speeds are very high. Going to set the camera on Program and keep checking the exposure settings.

You'll need to have the camera in both continuous shooting mode and continuous autofocus. You'll probably have overlapping from photo from photo. It sounds like it's going to be a mess. I would use that technique when panning subjects that are in motion.


I think I will keep the aperture at like f11 so focus is not an issue. Otherwise the camera may constantly seek focus.

I have been given an assignment to take massive numbers low res jpgs of trees, shrubs and other things for a total of about 5000 images. The customer says he wants to imbed them into the code of his website for better SEO. Never mind if that will work or not. I need help figuring out the best way to go about this

He wants a certain number of each subject. They have to be in focus and properly exposed but the composition doesn’t matter that much.

I have a camera that shoots 8 1/2 frames per second at 8 mp. It will take 40 jpgs before the buffer gets full and I have to wait. He wants to reduce the file size on his own.

My other camera shoots about 6 fps at 21mp.

Also I have a Canon XA50 video camera.
(Manual PDF attached)

The goal here is to have each picture look a little different but similar so I have to shoot in burst mode while the camera moves across the shrub or tree so that each shot is different.

Figuring out how to count each category of subjects and know when I have the right amount of each type of subject is one challenge.

Capturing pictures quickly is the other challenge.

I looked at the video camera manual and to take a still you press the screen where is says “still” or whatever. But I want to capture stills at a super high rate.

Can I set the frame rate on the video camera really high and then grab large quantities of stills using a software program?

I am aware that the file size of the video stills will be relatively small. I think that’s ok because he will reduce them further.

Otherwise I’m limited to 8fps and wait for the buffer to clear.

Any suggestions?
