So.. question ... do you get better sharper images using longer exposures?

Still trying to work out why my images are noisy and soft when I take one at night. I messed about with a technique today that involved a median stacking method in photoshop to remove noise. Do you do anything like that ? Or are you getting this good an image from a single frame?

It is driving me insane. My night time shots are shocking...
If noise is your issue, try DXO Optics. Best noise reduction software out there.
What exactly are you trying to shoot at night?

These are single shots with just a bit of post (added vignette and a little clarity boost). Longer exposure doesn't lead to sharper images per se. The long exposure is simply a result of choosing low ISO (helping reduce noise) with a reasonably narrow aperture (f11 to help with sharpness). The exposure with this ISO/f-number combination was around 10-sec so a tripod was required (helping with sharpness). Manual focus using LiveView with magnified preview. As you can see, the long exposure is really a symptom of the steps taken to minimise noise and maximise sharpness. It helps that the 6D is pretty good with noise levels and that this lens is pretty sharp but I don't think that either is necessarily best in class. I take the same steps on the night shots I've taken with much the same effect.

As far as I can tell, median stacking and similar frame addition/subtraction techniques are best suited for getting rid of genuine sensor noise (random) but will not do too much to help with sharpness

Hope this helps.

are you manually focusing to just before infinity? a trick that i have used (depends on ambient light and my light source power) is to flash a light to the furthest object i can focus on, and then turn the light off and shoot. But it gets wicked dark here in Utah :)

VW? which one?
[doublepost=1469844937][/doublepost]taken in canyonlands NP this past february. only THREE other photographers, and maybe 10 people total. Was such a 180 from the first time i was there in march of 2012.

if you get a chance to, a visit to southern Utah in winter is MAGICAL! so lucky i live 3 hours from here

After visiting Arches NP and driving through a lot of southern Utah a couple years ago I'm now a huge fan of that part of the world. It's beautiful there.

Regarding the dashboard you were close (kinda); it's from a '97 Porsche 911.

It does thank you. I am doing something wrong. Must be my focus technique.

Thanks. Must be something like this. I must be missing the hyperfocal focus or something. Just does my nut in. I have good equipment at hand and can get an occasional keeper or three at short range but the landscapes i take are so hit and miss.

Tha ks for your response. That picture in Utah is stunning. I am heading back out to the US again in November. going to Vegas for work and I am intending to add on some shutter time so hopefully do a few tourist things this time (too busy last few times)

Right, definitely the last lily - just to illustrate how much detail a non-macro lens can get. I prefer the composition of this one. Comments always appreciated.

My first comment is thank you. You just saved me £900! I am postponing my purchase of the 90mm macro I have been lusting after for a while. I am going to try the limited macro ideas I have with a combination of my legacy 50mm canon fd macro and my 70-200... These have been great...

You really do have spme amazing terrain in the US dont you? And tye quality of light that falls on it is beautiful.

We have beautiful landscapes in Scotland. The Highlands are incredible but the weather is too hit and miss so unless you want a moody or misty landscape then your shooting opportunities are a tad limited.

Erm... what's wrong with "moody and misty"? When photographers come to UK from, say, California, they love the idea that every day is different (not just "hot and sunny" all the time). :)

Clouds are okay, but a bit of sunshine wouldn't go a miss either!
Loving your garden pictures. Wish mine looked a bit more like that and a little less jungle!

One thing that has stood out in my mind looking at your photos, which I very much like by the way, is the abundance of nice weather you happen upon! To be honest, not having visited the UK yet, I find this encouraging but at the same time wonder if perhaps you have been somehow blessed with sunny days

Cheers

Yep, been looking at the nebula shot. I think for this we are into the territory of 100-200 individual shots then stacked together using something like regstax right?

A tracking mount is a thing of beauty! For a self proclaimed beginner you are producing some real nice images!

That was 15 20 second exposures stacked using Deep Sky Stacker. It's actually a bit of a process, DSS is a Windows program, and I'm on a Mac. I have Windows 10 installed in Bootcamp, so I edit it there and then copy it over to MacOS for processing using Pixelmator. It's not perfect; for some reason the image stack appears fine in Windows, but when I copy it over to the mac side, it's super dark. I then have to up the exposure a bunch in Pixelmator, which adds a bunch of noise. I'll have to figure out a better process.

Thank you for the compliment. It's been a few months since I've bothered working on photos like this. I should try to get some more done. :)
