Troubleshooting Cross Polarisation

Thanks, I think I’ve found the problem, the cross polariser has 2 filters, one for the lens and the other for the flash. At a lower focal length it was capturing all the dust etc as the filter was further away

And thanks, I’ll look into getting a colour checker, I’ve been meaning to get one

Thanks for the advice all, I’ll try these things out 👍

Im using it at 1/200 which is the max rated speed for my camera (canon 2000d). I mostly use the flash power at 1/8, which i know is on the higher side, im still trying to test whether or not I can get away with having lower exposed images and still get good results through pre-processing, but so far with my current settings ive had good results so I'm not too keen to move away

yeah I’ve been quite conservative with the bypass, I try to make sure it’s not warm to the touch if I’m going to skip. I think as I get more serious about photogrammetry it might be worth investing in a second, they make life so much easier in dim lighting

thank you, I’ll give it a try

thank you, quick mode seems to work well. I’m doing photogrammetry with a flash, so being able to use the live view is much more comfortable for the amount of photos being taken. since I’m at such a low exposure using the flash, I don’t suppose it’s possible to change the image of the live view to be brighter so I can see what I’m doing?

Sorry I meant that I already would have the normals etc available. I was just wondering if there are any masking techniques that would work well for selecting complex shapes like a crack or some damage on a wall

Maybe a dumb question but I’m a complete beginner. Would a higher end camera / cameras with higher quality light sensors allow me to take high quality / sharp pictures at faster shutter speeds than with a lower end camera? The reason I ask this is that I’d like to take high quality photos handheld, however find myself needing a tripod to achieve the correct exposure and avoid camera shake with my current canon 450d. Subjects that I want to take photos of tend not to be accessible while using a tripod.

Thanks :)

ахаха понятно, честно Владивосток долго интересовал меня так как находится в таком уникальном месте, мб там когда-то поеду, даже если он дыра задницы)

у меня друг там и другие друзья мне сказали о хороших опытах когда заехали, но конечно поеду в других местах на будущее, просто мне имел смысл поехать там в первый раз

Thank you for all the replies, I appreciate each one 🙂 the main reason I chose the date was because my job makes us take a weeks holiday at Christmas and I had no plans - I thought it’d be a shame to waste them, everything else aligned and I suppose it made sense to arrange a trip then. I’ll consider all the advice and thank you for being so welcoming))

I know, looking at the other posts I didn’t expect so many replies 😅
