On Samsung releases 12MP EX2F 'Smart Camera' news story (370 comments in total)
In reply to:

MrTaikitso: What does that ring around the lens do? Is it similar to that on the S100, Fuji, Sony and others, allowing for control of exposure, or purely for manual focusing and zoom? If it does allow for exposure control in conjunction with the front mounted thumbwheel, that will be great from an ergonomic standpoint.

If it is like the EX1 then the ring is not a control, just a cover over the threads that accept lens adapters.

On Technique: Digital Photo Collages article (107 comments in total)
In reply to:

CBuff: Author said "but if you made the mistake of shooting at full resolution, you will need to resize your shots first"

This is one of the worst advice I ever saw in an article.

Memory is cheap: get multiple memory sticks
Storage is cheap: buy more hard disks
RAM is cheap: jupgrade your PC,it won't crash

We use to spend fortunes on film, development chemicals, papers, ... It is so cheap now, I fail to see why would anyone would want to save by shooting low resolution.

Who knows... That shot that you took at a mediocre resolution might turn to be the stunner of the trip. Why take a chance for a couple of 00s?.

The primary constraint is RAM. Everyone has enough flash cards and disk space for full sized images. But when you place a bunch of them into a single canvas with multiple layers, it can really eat up the RAM. All computers have an upper bound on the amount of RAM allowed and if you're already up against that constraint then the only solutions are either to buy a bigger computer or do what Barnaby recommends: work with downsized images. Seems like a reasonable suggestion. And keep in mind that too many pixels can be a waste when it comes time to print. If the individual photos in the lead image here were shot at 12MP then the composite would be over 140MP. You'd have to create a print the size of a van to use all of those pixels.

On 2 Hour Challenge challenge (5 comments in total)

How will this be voted on and scored? Should we apply the same vote to all three photos in the set? Will the score be the average of the three? Or the max?

On Samsung doesn't deny Android-based camera news story (108 comments in total)

I can think of two advantages to using a standard OS on a camera. The most obvious is that it can become an open platform. That will open the floodgates for custom aps. And I'm thinking of aps to use during image capture, not postprocessing or aps unrelated to photography. Stuff like custom exposure programs and intervalometers will be easy to find and cheap. Third parties might even be able to patch around the annoying firmware bugs which Samsung seems to release. Lets just hope that Samsung makes it truly open.

The second and less obvious advantage is that by adopting a standard OS Samsung can now take better advantage of standard hardware processor platforms. The Android developers take all of the grief of porting to new processor platforms. Aps makers like Samsung only need focus on their ap. Think faster, more powerful devices that are developed quicker.

On An introduction to OLED article (67 comments in total)

I understand that OLEDs consume less power when viewing an image with black pixels since those don't consume any current. But when used as a viewfinder it is rare that pixels are completely black (i.e. hex #000000 in standard 24 bit RGB notation). More likely "black" pixels will just be very dim, #040202 for example.

My question is whether these "dim" pixels also consume less power compared to brighter pixels. My guess is "yes" they consume power proportional to their brightness. But it would be good to hear from a real OLED expert. Anyone out there who knows?

I'm using two cameras (Samsung HZ35W and TL500) that have OLED viewfinders and am very impressed with their image quality and usability in bright light.

On Landscape Photography Primer article (96 comments in total)

Nice article Carsten. I especially like how you have structured this so there's something for everyone from the gear heads who are willing to invest in a lot of equipment to minimalists who what to travel light. Hopefully the fundamentalist commenters won't give you too much grief :-)

Interesting to see that the 850 includes a GPS. I wonder whether Samsung has put any effort into fixing the problems of the WB650's 'mapview' mode or whether mapview is supported at all. mapview has a lot of potential if a few small kinks are worked out of the software.

On Introduction to Documentary-style People Photography article (66 comments in total)

Thanks for this article Giora, I find this info useful. I have one question: it seems as if many shots are made without the permission of the subject. How do you handle situations when the subject has realized that they have been photographed and object. Possibly they want money or perhaps they want the photo deleted.

As for other questions regarding the model release here I believe that photojournalists are exempt.

On Buyer's Guide: Enthusiast raw-shooting compact cameras article (286 comments in total)

This article should be subtitled "... and why you should shoot RAW". Great examples included here Barney ! The buyers of this class of camera are more likely to be on the fence regarding shooting RAW and you have provided a great resource to help decide which way to go.

I think that the title should read "CMOS *Image Sensor* Inventor..." CMOS itself (as a platform for digital logic) was invented back in the 1960s by Frank Wanlass.

On Introduction to Travel Photography article (40 comments in total)

Thanks for the article Dave. Though not a pro I learned a few tips from this article.

For those who are interested in ideas for travel photography without the expense/weight/bulk of pro gear the key lies in quality small sensor equipment. The smaller the sensor the smaller the lens needed. There's a recent crop of products that can produce some amazing results from small packages. I've been experimenting with using a pair of digicams that allow low light shots from 24mm F1.8 all the way to 350mm (though not f1.8!). They share the same battery and charger so the entire kit (charger and all) is smaller and lighter than a basic enthusiast grade DSLR body. And cheaper to boot. Plus if one camera fails or is lost you've got a backup.

Though this rig can't quite compete with pro DSLRs in IQ it does get pretty darn close. And the small bulk and weight allows you to move a lot faster and farther possibly capturing images that would have been missed with a larger pro rig.

Bob Meyer: The question I have, which this doesn't answer, is about private property that is effectively a public space, like the outdoor areas of a shopping center. Do rules for a "public space" apply, or rules for "private property"?

Thanks for the correction pL86. Since I live in CA myself I'd be interested in the which state laws apply to the shopping mall case you describe. So if you know where to look for that info please let us know, it might come in use.

In reply to:

thielges: Here's a tricky situation: As the ACLU guidelines clearly state you are free to shoot from public property but on private property the owner has the right to ask you to stop and/or leave. Sounds fair.

But what if it is unclear whether or not you're on public property? For example some publicly accessible roads are actually built upon private land. The public jurisdiction doesn't own the land but they have a legal easement to maintain a road across the private land. The public/private status of the land beneath the road can change every hundred feet or so and there is often no good way to recognize where the transitions are without consulting the property line maps (platt books) which are often secluded away on the city/county records office.

I was arrested once shooting from a publicly accessible road on these grounds. Though they released me shortly afterwards without charge it was really annoying to go through the detailed search while the best light of the day waned.

cplunk -Yes, most roads are built on a wide public Right of Way. However I have intimate knowledge of some public roads that lie atop private land in California. And in one case the property line runs to the center line of the road itself! So northbound traffic is on property X and southbound is on property Y.

On Photo Tip: Five for Five article (111 comments in total)
In reply to:

Alex Notpro: I'd like some tips on how to organize a photo collection when you have 5x more photos laying around.

Hi Alex - I won't burden you with the complexities of my overwrought workflow but here are some basics that help me keep the volume under control. Basically I trim down images throughout the process from shutter to gallery. Here are the opportunities in order:

- Cut 'em off at the source: don't shoot something you know will be uninspiring. It is easy to be too caught up in the moment and forget that the artifact you produce isn't the scene but a 2D approximation of the scene. Restraint

- review in the field and delete bad images in-camera. It helps to have a sharp OLED screen for this

- I shoot multiples of the same subject for the reasons stated in Amadou's article plus simply as AF safety. In the PC, I'll review that set and kill all but the one or two best. I might even delete a perfect photo if there are other perfect specimens.

- Grade photos and select the best. Usually that's 1-2% for me. Keep the other 99% but file them out of the way.

-regrade ruthlessly b4 showing.

On Photo Tip: Five for Five article (111 comments in total)

Thanks Amadou. Though some of the commenters here complain that this tip is too basic there are so many valuable basic tips that it makes sense to even seasoned photographers to review them periodically. I have a list of about twenty such basic tips that I refer to from time to time. Each is simple in its own but it is hard to keep all of them in mind all of the time. So sometimes I focus on one or two tips for a session and that helps it become an automatic reflex.

I think I'll focus on your 5of5 tip next. Keep 'em coming and and don't let the haters get you down.
