Duplicate shots

[Jim Kuo]

Priya and I often go on the same trips, however, we have different choices of equipments and different ways of seeing things, it's rare that we both come back with very similar photos.

We caught our first "duplicate" shots in our recent trip. I used X100 and Priya had her Nikon D40 + 20mm F2.8D. We both happened to shoot in aperture priority at F11, and the cameras picked the same shutter speed for us (1/125).

X100 - 12M sensor with 23mm lens.
D40 - 6M with 20mm.

I think the specs are close enough for a non-scientific and fun comparison. X100 do have twice as many pixels. Can you guess which one is shot by which?

These are RAW files straight from the cameras. I cropped and levelled them a little. By the way, we both shot hand held, and this is not meant to be a serious head to head. Just some non-serious relaxation on a Monday night after battering Fuji for messing up their latest firmware.

Nikon then Fuji I reckon?

 

[Jim Kuo]

Keep the answers coming! I will revile the correct answer tomorrow .

Have you cleared the exif to stop people cheating?

 

[Jim Kuo]

Yes

 

[Chris Dodkin]

Fuji is #2 I'm guessing - purely based on the level of twig and grass detail

 

[Hamish Gill]

My guess is based on colours on my iPhone screen

 

[Ben Jennings]

I reckon Fuji is #2 because the grass seems a little more defined (although on a side note, the colours on the first are really nice).

I'd go for Nikon as No 1 as it has a similar look to other Nikon raw files. And there appears to be more detail and fine contrast in the second.

I was going for Nikon as No 1 as it has a similar look to other Nikon raw files. And there appears to be more detail and fine contrast in the second. However, I think I can see some sensor spots in number 2 and that must mean dust and so must be the from the Nikon.

I think there are enough replies for me to revile the answer. Pete (2nd answer) is the only one who got it right. Ben was close .

These are the links to the photos with EXIF info.
#1 - X100, F11, 1/125, ISO 200

#2 - D40, F11, 1/125, ISO 200

As I mentioned, this isn't a very scientific test. There are a few factors that might contribute to the "softness" in #1. I think I picked Astia film simulation (X100), and I am usually unable to get clear enough shots at 1/40, where as Priya can get useable shots at shutter speed as low as 1/10 or 1/5. Also, we were both manual focusing, she was using a D lens on D40, and I was testing the DOF stuff, setting focus to around 2.5 m at F11.

We were surprised to find how good/detailed the D40 picture looks, there is still life in this little light weight 2006 DSLR yet. Of course in a less than optimal situation, it wouldn't perform as well, but it did deliver pretty amazing output in the conditions on this trip.

ps. What sensor dust Pete? You were able to spot sensor spot in image reduced to 800px in width?? Amazing!

 

[Dan Cattermole]

You don't miss nothing do ya Pete!

I'm guessing Nikon first.... Although I have no clue why, but just for fun and games

 

[Pete Askew]

Two the left of the lines Jim. There are a few others as well.

Ok, I see them now, on 100% crop in the original image, after you pointed them out to me...

I am very impressed by how you were able to spot them in the jpeg attached in this post!!

I am not worthy...

 

[Pete Askew]

I didn't notice them when I first looked at the images but when I posted and scrolled the images I could see faint marks that moved with the second but none on the first. So I zoomed in to make sure they were what I thought they were.

[Jim Kuo]

It's a pretty amazing ability .

Thanks for the sensor cleaning link. She shoots D300s normally, D40 is only her backup kit when she is feeling lazy. So I don't think Priya is that bothered, but I think it's still worth a few squeezes of blower to sort out the easily removable parts.
