In order to make a fair comparison, I would take at least 4 pictures of the same exact subject, preferably a static one, using a tripod to exclude any camera shake. Two, one at 500mm and maximum aperture and a second stopped down one or two stops. I would then take two more at 600mm, again, one...

I would agree that number 2 looks a little sharper. I would point out that number one is noticeably noisier, which introduces another variable to the mix, unless that was the point of the exercise. Also, these are small images. To adequately determine if an image is really sharp, I normally...

Gigapixel is the least used of the three for me. Much of that is that I don't have a lot of cases where I need what it will do. I would recommend you try it on old photos. Here's a picture of me, my dad and Bossy. I ran it through Gigapixel, which automatically upsized it 2x. I then resized it...

EXIF shows a different time stamp. Not by much, but different.

You could try sending it to me in a personal message. Not sure how large a file you can attach. If all you are looking to do right now is to post it here in Landscape Photos, it won't really matter after it's downsized for posting.

Keep in mind that Topaz is specific editing, versus a general editing program. It is very good at sharpening, upscaling and denoise. You cannot do things like basic adjustments of color, contrast, shadows etc. Most of the good general editing software packages will allow you to do operations...

SPV, if you are looking for some editing software and don't want to buy it right now, you might look at Nikon's NX Studio. It is free and available on their website. NX Studio download page It will not do many of the things that Lightroom, Photoshop, Topaz, and other software will, but it's...

He might have bitten off more than he could chew. I know snakes can get down some amazingly large prey, but that seems a bit extreme. Do you know if he succeeded?

The first thing I would do is to bring the ISO down. The Z6 is supposed to have very good low light performance, but IMO 6500 is a tad high, especially since you are shooting off a tripod and can afford a longer shutter speed. I would also bump up to at least F5.6. Most lenses benefit from at...

Not displaying. Says I must be logged in.

I like the first one the best. Some of that may be because it has a clearer reflection of the duck's head. Another thing in it's favor is that the gold color extends throughout the frame, giving better separation to the subject.

If you go to their website here: topaz link Just to the right of "Buy for $199" there is an option for: "Already own Gigapixel, DeNoise, or Sharpen? See your special price →". Click on that and it will take you to a page where you log in and it will give you a price to upgrade.

Big Kitty!

Yes. When you load a file, it analyzes the image and decides what it needs and how much. When I use it with my macro photos it normally doesn't add any denoise because I'm shooting at 100 or 200 ISO. You can also manually turn on or off one of the three, and use sliders to adjust the amount...

I've had some co-workers that weren't too sharp. That was just the way they were made.

Shooting through a curtain?

Sensor size makes a difference if you are thinking about your 50mm lens on a DX camera as 75mm effective.

My Z mount 105 F2.8 micro lens continues to impress me, even on a lowly 24 MP FF sensor.
