I take photos of computer hardware for sale on ebay. I had been borrowing a camera for photos (Olympus SZ-16) and the camera will be able to focus while very zoomed in to a device while relatively close. But since it was borrowed, I ultimately needed to buy my own camera. I'm not savvy on technical specs or anything like that. I just wanted a point and shoot camera that was modern and had good zoom. I didn't know about "Minimum focus distance" when I went to make my purchase.  So I bought a Canon SX740 HS. Took me a while to figure out the camera... turns out it has REALLY BAD minimum focus distance. The camera refuses to focus when zoomed in. How can I fix this? If I can't fix it, what stat should I look for for focus distance when zoomed in?  Here is a picture I took with the SX740 on a tripod. The object is about 40 inches away from the camera body. This is the closest I can zoom in before the camera refuses to focus. I can't even manually focus it to be in focus if it is zoomed in any further.   And here is a picture I took with the SZ-16. I can zoom in to the maximum 24x and it'll focus perfectly. Same deal, on a tripod, object is 40 inches away from camera body   So why does the SZ-16 have much better minimum focus distance than the SX740? What stat should I look for with respect to focus distance while zoomed in? What camera would you recommend for close-up telephoto images? Sorry if I used the wrong terminology. I think I'm going to return the SX740, because getting these super narrow field pictures is critical, especially if the item has a tiny defect that I need to display.
Hello recently I went to best buy and played with a Nikon B500, it was great. I was able to focus on the smallest things, close or far, zoomed all the way in and all the way out. So I went on the internet and found out that the B700 shoots in raw so I got it instead thinking it was better. Only I cant get it to focus on anything close up, weather in macro or not after like 25% zoom it no longer focuses on anything no matter what settings I put it on leaving me to think that I should have gotten the cheaper B500. It may not shoot in raw but at least it would be usable. I am fairly new to photography I had a friend with much more experience come over and try to figure it out. He told me that my camera has a range that it is able to focus on. Only the cheaper B500 focused on things way more zoomed in and with the camera much closer to the object so it doesn't make much since to me. So my question is why wont my camera focus on macro shots (weather in macro or not)?
Instead of the constrained 45 degrees that happens when you press C, is there a specific angle I can get for example 35 degrees instead?   It's currently cut at 45 degrees in the attached image and I need it to be 35. Messages on Macs don't work I've tried every suggestion I could find on Apple forums. Deleted .plist files, removed message caches, reset passwords, coordinated sign on/offs between my iPhone and my Macs, reset iPhone and reinstalled Mavericks on my Macbook Air. All pointless exercises.   I suspect it all started because I jailbroke my iPhone using Pangu. It may or may not have been the culprit, but my problems started a couple of days after I did it. All my phone conversations went green and stopped synchronizing with Messages apps on my Macs. Trying to send a new message from Macs would result in either "Your message could not be sent" error with a warning icon next to it, or:     XXX is not registered with iMessage.   So I restored my iPhone to factory defaults using iTunes. That didn't help immediately, but in a day or two, my conversations with other iPhone users went blue. So I am happy that works.  So now I sacrificed my Macbook Air to try and make messages work on it. I reinstalled Mavericks several times, each time trying different approaches: not immediately signing into iCloud, not associating an iCloud profile with login profile, etc. Nothing helps. I launch Messages app, it asks me to sign in (and I do, successfully), and then nothing goes through.   Sending messages to myself also works inconsistently. Yesterday, whatever I sent to myself (using phone number) would appear delivered to the same window, but not on my phone. Today I get "... not registered with iMessage" error. Link renders differently on client and server side when preceded by a special character When editing a question on , I observed that a link which was not rendered in the post was hyperlinked in the edit preview (see pictures below). I tried reproducing it in the  to see if this also happens when the post is posted for the first time and observed the same. It seems to be a bug after the shift to CommonMark, leading to the different rendering of links on client and server-side. A link following a special character (without any space) is not hyperlinked in the post but is hyperlinked in the preview. A link separated from the special character with a white space appears to have no such problem. (see pictures below and my ). Link not hyperlinked in post  Same link hyperlinked in preview How do single photons travel from here to there I know there have been similar questions but I'm still unclear what the overall consensus is. (1) I assumed and have read that photons travel in straight lines unless deflected by gravity but there are conflicting theories. (2) I have heard that single photons takes every possible path but that makes no sense. Why would a single photon traveling from here to the moon go to every other place in the universe along the way.  (3) I can understand a single photon traveling as a particle or packet of energy but I have a hard time understanding a single photon traveling as a wave. I have never understood any attempts to answer this.  (4) Does a single photon have a frequency and what causes the frequency? If not then how does it have energy? I have many questions about single photons and their frequency. Prove that $\liminf x_n = -\limsup (-x_n)$ How do we "restore" notepad after crash? I was running NotePad and Chrome when my computer suddenly shuts down.  After reboot, chrome was able to "restore" itself such that I didn't lose any data.  However, how do we "restore" notepad.exe? How would you know if your (high dimensional) data exhibits enough clustering so that results from kmeans or other clustering algorithm is actually meaningful?  For k-means algorithm in particular, how much of a reduction in within-cluster variance should there be for the actual clustering results to be meaningful (and not spurious)?  Should clustering be apparent when a dimensionally-reduced form of the data is plotted, and are the results from kmeans (or other methods) meaningless if the clustering cannot be visualized? Proving question on sets I am unable to understand this question. I have to say whether its true of false and then prove it but I can't proceed with the question unless I understand it.     Let $S$ be the set of stars in our galaxy. There is exactly the same   number of subsets of stars in our galaxy as there are functions   $f:S\rightarrow\{\alpha,\beta\}$ Consider a set $A$ of $10$ integers, $A = \{a_1,a_2, \ldots ,a_{10}\}$. Prove that there is at least one subset of $A$ whose sum is divisible by $10$. I recently printed a paper that asks to prove the "amazing" claim that for all $a_1,a_2,\dots$  $$\sum_{k=1}^\infty\frac{a_1a_2\cdots a_{k-1}}{(x+a_1)\cdots(x+a_k)}=\frac{1}{x}$$  and thus (probably) that  $$\zeta(3)=\frac{5}{2}\sum_{n=1}^\infty {2n\choose n}^{-1}\frac{(-1)^{n-1}}{n^3}$$  Since the paper gives no information on $a_n$, should it be possible to prove that the relation holds for any "context-reasonable" $a_1$? For example, letting $a_n=1$ gives  $$\sum_{k=1}^\infty\frac{1}{(x+1)^k}=\frac{1}{x}$$  which is true.  The article is How can I determine that I am looking at the block I need? During a sunny day the walls of my house warm up (no surprise). My question: how much of this warming up (if any) comes from visible light? I associate infrared with thermal energy. If my house was floating in space (to prevent any thermal exchange with its surroundings) and I installed a giant infrared (and UV) filter between it and the sun, would it still warm up (compared to its rest temperature in full darkness)? Inverse of Strictly Monotone Function Can I leave the UK and come back in, on a Tourist visa? I am firmly convinced he is innocent and his accusation is the result of the police conspiracy.     I am firmly convinced he is innocent and his accusation is the result of the police's conspiracy.    Which sentence do you think is a better choice? Variable declaration placement in C I long thought that in C, all variables had to be declared at the beginning of the function. I know that in C99, the rules are the same as in C++, but what are the variable declaration placement rules for C89/ANSI C?  The following code compiles successfully with gcc -std=c89 and gcc -ansi:  #include &lt;stdio.h&gt; int main() {     int i;     for (i = 0; i &lt; 10; i++) {         char c = (i % 95) + 32;         printf("%i: %c\n", i, c);         char *s;         s = "some string";         puts(s);     }     return 0; }   Shouldn't the declarations of c and s cause an error in C89/ANSI mode? How to determine the class of a generic type? Galois group of irreducible cubic equation The polynomial $f(x) = x^3 -3x + 1$  is irreducible, and I'm trying to find the splitting field of the polynomial.  We've been given the hint by our lecturer to allow an arbitrary $\alpha$ to be a root and then to check that $\alpha$ is a root, then $2-\alpha^2$ is also root. I've done this with no problem.  My issue is since this is a polynomial of degree $3$, there must be another root that is somehow related to $\alpha$ so that I can create the splitting field and in turn the Galois group of my polynomial but I have no idea what this last root could be. Layover at Dusseldorf and Frankfurt, category A or B visa? I am a Indian citizen in the United States on a F-1 visa.  For the summer break, I am traveling (round-trip) from Chicago to New Delhi via Dusseldorf-Frankfurt by Lufthansa airlines. My onward Journey would be on July - 8 and return Journey on Aug - 11.  My layover will be of 1 hour 10 mins in Frankfurt and 3 hours in Dusseldorf.  I would like to know if I require Category A or Category B Visa. If not, what type of visa do I require for the Schengen visa for my transit. How I can apply for the same?  I tried to find slots in German consulate but all slots are full before my departure date. If I don't get the Schengen visa, I cannot travel and will loose all the fare (since my ticket is a non-refundable ticket). Is there any other way I can tackle this situation. Add review queues to Android app I know there are some similar posts on adding review queues to the mobile web page. However, this is regarding the Stack Exchange Android app. I really would like to review posts and edits from the Android app, however this isn't included in the app yet. I'm not sure how it would be implemented; maybe there could be a button or something for review. Could we please see this?
