Why use a smallish aperture with diffraction blur and risk camera shake, when you can open up the aperture two or three stops and increase the speed accordingly? there's no depth of field issues here! I'd try one stop down from fully open, 1/500 or 1/1000 at ISO 100.

This is a snapshot of China now, poised on dominance. The article paints a picture of China as the savior of post colonial Africa when it is just economic colonialism, locking up resources and trade. Still the largest polluter, China leads in alternative energy technology, production AND consumption. Part of the push to tap into the domestic economy. So while we're distracted with the pettiness of an emotionally unfit POTUS, a******n, public health, gay issues, wars, guns and religion, China is just getting on with it, with or without us.

http://www.salon.com/2017/01/25/china-steps-up-as-global-leader_partner/#comments

This article was originally published on The Conversation.

Chinese President Xi Jinping’s appearance at last week’s World Economic Forum shows global leadership is shifting, not drifting, toward Beijing. The most vigorous defense of globalization and multilateral cooperation was mounted not by an American statesman, but by the president of the People’s Republic of China.

and

Speculation is mounting that the United States, with Donald Trump cast in the role of president, will ignore international challenges, renounce global responsibilities and abandon friends and allies.

and

But never before has China so forthrightly stepped up when the United States appears to be stepping away. As scholars of Chinese strategy and the intersection of science and politics, we see how Beijing’s ambitions and interests will affect its engagement on a range of important international issues.

and

The case of c*****e c****e

C*****e c****e policy is one good example of this trend. Commentators warn that Trump’s pledge to withdraw the U.S. from the Paris climate agreement would let China “off the hook” for curbing carbon emissions. In fact, China put itself “on the hook” in Paris for reasons having little to do with the United States.

China’s most urgent atmospheric problem is not carbon dioxide. It’s combustion toxicity from burning coal, oil and biomass. The Chinese these days don’t look through their air; they look at it. And what they see, they breathe.

and

China is already the world’s leading producer of renewable energy technologies. More remarkably, it is also the leading consumer. And in January, it announced plans to invest an additional US$360 billion in renewable power between now and 2020. That’s $120 billion a year.

and

A savvier and more probable move is for China to assert – for the first time on a major global issue – moral authority. Chinese diplomats are already reassuring the world that China will keep and even expand its climate commitments. This message conveys Beijing’s resolve not to let to let multilateral greenhouse gas mitigation collapse, and show the way out of a crisis whose agreed solution is threatened by others’ malfeasance.

and

Likewise, Beijing is asserting greater leadership in other areas once led by Washington. With the demise of the T***s-Pacific Partnership, which Washington negotiated with 11 Asian countries excluding China, Beijing is promoting its own Pacific trade-and-investment framework excluding the United States.

Even more grandly, Xi is articulating an alternative vision for global economic growth. The model focuses on physical investment, especially in t***sportation and IT infrastructure. In this, it is linked to the new Silk Road project, through which China is expanding linkages across Eurasia by integrating railways, ports and information networks into t***snational corridors. The Chinese approach also does not rely on portfolio investment and central banks exertions to drive growth – a sharp contrast to Western policies

and

Ceding global moral authority to China would be a high price for America to pay for the pleasures of political posturing. Yet a China leading by example would have a greater stake in its own reputation, and the greater that stake becomes the more engaged China becomes. Such a China, we believe, could profoundly benefit the world.

I'm a beginner looking to get into photography when I retire this summer. I will be using it for various wildlife including birds and walking on the C & O canal and Antietam Battlefield and on vacation to the Oregon coast. Would like to have a lens that could be used 90% of the time. I will be carrying the camera around my neck most of the time while walking. My budget is no more than $1,200.00. I do not want to buy something that in a year I would not like. I started out wanting to buy the D3400 Nikon bundle. Now I'm thinking about buying the D7100 Nikon camera after some research. The new camera alone sells for $700.00. The other option is the Nikon D7100 bundle with AF-S DX 18-140 f3.5-5.6VR lens for $1,000.00 or the bundle Nikon D7100 with AF-S DX 18-55 f3.5-5.6 G VR II and AF-S DX 55-300mm f4.5-5.6 ED VR for $1,050.00. Someone mention just buying the D7100 and getting the Sigma 18-250mm f3.5-6.3 Macro Nikon F mount for $350.00 or the 18-300mm F3.5-6.3 Macro for $500.00. Can someone recommend a lens for my needs that cost around $350.00 to $500.00. I'm not familiar with the other kinds of lenses. I'm not sure about buying used or refurbished. If someone has a better recommendation or suggestion , please let me know...Thanks

I won't join the discussions about which body (OK, in your shoes I'd get a refurb D7100) but for lenses I would pick the 18-55mm f/3.5-5.6G VR II 'kit' lens- astonishingly good for the money, and AF-S VR Zoom-Nikkor ED 70-300mm f/4.5-5.6G IF, still very good value, enough reach for wildlife, and in a few years if you go full frame, it's still useful. Don't worry about the gap between 55mm and 70mm - the resolution is plenty to allow a bit of cropping with a 55mm image. Again, refurb is fine.
Good luck.

Those are outstanding! And handheld! It's hard enough
on a tripod.
I am not a pro, so $5,000 lenses are out of the question.
I am thinking either the em5 or em10.


Thanks- I was very pleased with the butterfly- only time for a quick snapshot. The IS may not be up to current standards on the Panasonic 100-300 but they're pretty good for the cost.
I would go for the em5 if affordable- splash proof saves a lot of worry. The Mk II looks wonderful, though I've not handled one yet.

Will the MFT Panasonic lenses work on the Olympus MFT cameras?


These both taken with my OMD EM-5 Mk 1, with a Panasonic 100-300mm at full zoom. The peacock butterfly was about 12' away, the moon about 240,000 miles! Both handheld. Both from jpegs, butterfly sharpened a touch, moon cropped a lot, white balance adjusted and sharpened a touch. If I'd used my D800 with Tamron 150-600 both would have been a little better, but not much. Good enough for my purposes.

What would you recommend?


I asked for that! A very simple question, but with a very complex answer. There is an inevitable compromise to be reached, where final image quality depends on sensor size, which reflects camera/lens size/weight, and, to a great extent, cost and the learning curve involved in learning to drive the thing! Also to consider is your future plans- what you expect to mainly photograph, for example landscapes or wildlife, which will give some idea of the focal length range you will need.

The logical next step would be a similar camera to what you have- a 'bridge camera' - fixed lens but with an extended zoom range, but with a larger sensor, such as the Panasonic Lumix FZ1000 or Canon PowerShot G3 X. But in a year or two you may wish you'd gone for something more advanced, such as a mirrorless changable lens camera or even a full frame DSLR. Unfortunately, with the latter, to get a similar image to yours, but MUCH better, would cost about $3000 for camera body and suitable lens, and a lot of learning and experience. It would also be heavy, and you would need a decent tripod much of the time. I said it was complex...

This link will take you to a pretty useful site and should open at the bridge camera section, but you can navigate around to a general 'which camera for me' and to other types of camera. Good luck!

Lovely scene, but not good technically.
It's not you, it's the camera! That's about as good as you will get, taking a scene like this with high dynamic range, using a camera with a tiny sensor at ISO 800. When you're ready, and as funds allow, a larger sensor camera will give MUCH better results.

When you are editing portraits, do you crop BEFORE you edit, or do you (as I do), crop AFTER you edit allowing the flexibility to create multiple sized crops later?

I hear so many "PROS" talk about 'cropping' BEFORE - especially in Photoshop. Why take time editing something you won't use, they say! But what's discarded in Photoshop is gone forever and it's a bit hard (impossible) to create a usable 8x10 AFTER it was cropped to a 4x6 format, i.e.: chopped toes/elbows, etc. Also, it is hard to explain to a "Brides Mother" that the 16x20 Canvas Print she wants out of a 4x6 tight cropped Proof is not available! As a note, suggesting the 8x12 or 12x18 to the client does not count and isn't a fail safe solution. People LOVE their 8x10's, & 5x7's!

Keep in mind, this question is about editing People rather than wildlife or landscapes - unless - those images are contracted and the client has a stake in framing of the final product.

Thanks! And More:

Please feel free to expand on methodology and reasons why.

Here is one of mine: In Lightroom, I create a "Copy" of the final edited image, for each crop size I develop. I also "color code" each size differently. This way, I can sort the"yellows" (for 5x7) and get all of the 5x7's at once for a batch export. When I export a 5x7, I will include -57 in the batch naming process to distinguish it from the same image cropped to an 1114 - 11x14.

Thanks!!!

I've always cropped first, without thinking and for no good reason. Having read this thread, I now know better! Many thanks for raising the issue.

I did not mention DOF as that is an artifact that arises only because the human eye has a limit of resolution which anounts to one arcminute of angle. When the rear lens principal plane is at a specific distance from the sensor plane, there will be one and only one distance from the front principal plane to the in-focus subject. The rest if the so-called DOF is 'tolerably' in focus.


Agreed that DOF is in effect the range that is tolerably in focus, but that is a feature of the sensory apparatus, and its 'circle of confusion'. Since we're talking cameras and lenses, that means the camera's sensor. Absolutely nothing to do with the human eye, unless discussing direct vision devices such as telescopes, binoculars and microscopes, although then things are confused by the eyes' own focusing abilities.

That makes sense to me. There are processors that can easily keep up with analyzing and compensating for a 100 Hz vibration but probably they are not in many cameras. I'm thinking now of bringing along some material, foam rubber perhaps, to put under the tripod legs to absorb the vibration from the ship's engines.


I will be very interested to see how well this works. A problem with rubber might be that it would allow the tripod just to resonate -it's not well damped. It might be worth trying small squares of carpet - I would try four thicknesses under each leg, with the carpet pile face-to-face. That works quite well at damping movement.

Agreed, do not confuse the two, but how can you tell which from the picture.


Motion blur is usually in one direction, focus blur is generalised. For example, a distant light, such as a star, leaves a line with motion, but just looks 'mushy' when focus is poor. Most images have highlights which help to distinguish.

Since most of the population has oriental (Chinese-type) features, and the second most common has Indian- Asian features, it seems unlikely that a blend would look Brazilian.
