comment Should I buy filters or step down adapters for multiple lenses?
Agreed. I have a few of those but the problem i continually run into it that the rings and the filters are from different manufacturers and the threads can bite to the paint that i am unable to separate it. When it's either too hot or too cold, the ring and the filter seize and I have to take it apart when home in a room temperature. I managed to damage the coating on a filter too trying to unscrew the ring.

Perfect! Thank.

I would love to see one of these and the results. Sounds fun!

comment Why does this satellite image of an airplane in motion show red, green, and blue bands with strange artifacts?
Agreed - this is likely an aerial photo. Until recently, yesterday actually, satellites were not allowed capture imagery better than 50cm resolution. This image is more like 20 - 30, possibly better.

This question should be moved to GIS Stack Exchange as it is related to remote sensing.

comment Canon 6D lensflare
Both lenses are "budget". Pro and newer lenses are better at controlling flare but there will always be lens flare under certain situations. Any protective glass or filter will make this worse. I suggest you try a new pro lens of a similar focal length and compare results.

comment Strange color difference between Rebel XS & 70D
Good answer as always! Both cameras have a different sensor (slightly different size) and different image processor DIGIC III as oppose to DIGIC 5+. I personally notice a difference between my 2 bodies, 60D which uses DIGIC 4 and 6D with DIGIC 5. White balance aside I also find the 60D images somehow "dull" compared to the 6D - always preffererin the newer to the older.

OMG, you didn't...

comment Night photo with Leica 25mm: blur at f/1.4
In low light, you should have your camera on a tripod. I am not familiar with this particular lens but to focus in pitch dark you normally focus to the infinity mark (to shoot stars for example) which should be on or near the focus ring or you bring a flashlight and and focus onto an illuminated area then turn the light off and take the shot. In the dark a solid tripod is a must. There are different techniques for different situations but night photography is challenging but fun and results can be rewarding.

comment Which special effects filter produces circular highlights?
Thanks. The example is only remotely similar to what I am looking for. Please see the example I posted with the question.

comment Which special effects filter produces circular highlights?
I see! great idea the UV filter! so a circular sticker or a donut sticker or something like that. Thanks! Will experiment!

Thanks @Matt. Can you provide a link, example or more info. Do you mean something along the lines of this?.

comment Which special effects filter produces circular highlights?
@EsaPaulasto - I am very certain a filter was used I just don't know which one. I have very little knowledge of special effects filters (other than CP, ND) and would like to try producing this effect. Although Magda does use lenses that produce donut shaped bokeh it wasn't used here.

comment How to compare two different cameras in regard to a low light performance?
What research have you done so far? Which way are you leaning and why?

What is a typical post processing you do with most of your images?

comment Do professional event photographers commonly require payment in full before a shoot?
Fair points. Good to know. Thanks

comment Do professional event photographers commonly require payment in full before a shoot?
Thanks for your input. I am a little surprised because nobody else does this - services are provided, an invoice is issued, expense is approved and the bill is payed. We are an international gold mining and exploration company and very well known in that region. There is practically no chance that an invoice would not be payed.

comment What is a better marriage for my Canon 70-300 L lens: A 7D or 5d Mark iii?
Nice answer! "I am able to time the shots, rather than gunning through a sequence" makes a lot of sense

comment What is the cause for this diffused artifact around the sun?
@FinerRecliner - yeah, it visible in every shot. I am out of ideas - will leave it to the experts to decide. Almost look like there are a few clouds or haze.

comment What is the cause for this diffused artifact around the sun?
Can you post the 3 unprocessed shots? I get a similar effect when I overcook an HDR but I learned to expect all sorts of unpredictable flaring and undesirable effects when shooting sun against a uniform sky. If you can see the result in the camera preview perhaps there is a way to combat it in the field bu trying different settings. What were the the other settings aside from the obviously closed aperture? If it was an HDR processing issue i would suggest using a different software - I get better colour uniformity in Photomatix but stronger sky effects in HDR Effex Pro...
