Great Advice On How To Get Great Looking Photos
Experimentation is the best way to learn how the various camera setting will affect your final product. This is a great stroke of luck and excellent timing. These tips will get you on your way to taking better pictures.
You need to make sure that you have the right white balance setting on your camera if you are taking pictures under fluorescent lighting. You will notice that fluorescent light highlights the blue and green light spectrum and will require post processing in order to balance your tones.
You should think about your approach before you start taking pictures. Spend a few minutes brainstorming and coming up with ideas that might improve the quality of your shot. Photography is just like art; it shows when attention to detail and a well-conceived plan are executed. You will be inspired and see much better results, if you take this approach.
Be vigilant about charging your batteries, as missing a great shot due to dead batteries would not be cool. Digital cameras with LCD screens use a ton of power, so make sure they’re fully charged prior to use. If you’re really dedicated to always being ready to shoot, bring along an extra set of camera batteries.
Get close to the subject of your photograph. When you are too far away, it is harder to see the details in the resulting photograph, which can prove quite disappointing. Make sure you can distinguish details on your subject that will attract your audience’s attention.
Get quick with your shutter finger. If you take too long, you’ll never get the perfect shot you envision. Your subject might run away or change position so that the moment you wanted to capture gets lost. So therefore, the faster you are when you are taking your photos, the better off you will be.
Whether looking at a natural scene or one you have set up, including repetitious patterns will give a rhythm to the photo and add interest. Patterns help draw the eye to a photograph and make it more interesting to view. You can get some interesting backgrounds and angles doing this.
Night photography is a whole new, complicated subject of its own. You should utilize proper lighting equipment during nighttime shoots, as natural light will be unavailable. When photographing at night, you can employ the use of slow shutter speeds and a variety of artificial lighting options.
It’s fun to learn the basic concepts involved in taking good photographs. Even if you were fairly knowledgeable before, you are probably an expert now! The tips given here should help you start honing your photography skills.

401 of 403 people found the following review helpful Unhelpful user’s manual, microscope provides two fixed levels of magnification, appx 20x and appx 400x, November 9, 2009 By Paul Clifford (Newark, CA) – Amazon Verified Purchase(What’s this?) This review is from: Veho VMS-004 Discovery Deluxe USB Microscope with x400 Magnification & Flexi Alloy Stand (Camera) I just bought this microscope and after some initial disappointment, because I didn’t really know how to use it and the documentation that comes with it is almost useless, I am now quite pleased with it. There is some confusion in reviews here over what this microscope can do — is it really a 400x power microscope? The advertising describes it as “Magnification: 20x – 400x (Plus digital zoom in 640×480 mode)” Does that mean it can continuously zoom from 20X to 400x? The manual that comes with it does not really tell you how to use it. So I did a little experimentation, and found that it really has two fixed magnifications, appx. 20x and appx. 400x.There is a cylindrical drum you can twist for focusing the microscope. As you turn it an internal lens moves up and down the barrel, changing the distance to the specimen. On the drum, there’s a scale, with markings from 20 to 400 on it, that is quite misleading — it suggests that you can optically zoom continuously from 20x to through 400x. But that is not the case. Instead, there are two fixed magnification levels, one nominally 20x and one about 400x, corresponding to two different focus locations, and they do not correspond to the locations on the scale you would expect!Using it at 20x power:If you place a specimen, like a piece of paper, directly under the microscope and place the clear plastic end of the microscope directly on the paper, the 20x focus occurs when you turn the drum beyond the top of the scale, past the 400, then a little past the 20 mark as the scale starts repeating. At this focal point the internal lens is moved up the tube, far from the specimen. The field of view is 13.5 mm. You can then move the microscope farther from the paper, readjusting the focus as necessary. You can even move the microscope quite far from the specimen, and still be able to focus it with 20x magnification. When it is focused at infinity, (at the extreme end of the scale, about 60 over the top), the field of view is 11.2 degrees, or about 3″ wide when the subject is 12″ from the end of the microscope.Using it at 400x power:To get the the 400x magnification, again place the clear plastic end of the microscope directly on the specimen, say a dollar bill. The 400x focus location occurs when the drum is rotated beyond the bottom of the scale, to the 400 below the 20 mark. At this point, the internal lens is moved down the tube, to nearly as close to the specimen as it can get (about 22mm). The field of view is only about 0.8 mm, or 2 degrees. Most users would never notice that the microscope can focus at the 400x magnification: to attain it you must move the focus lens to nearly the full bottom of its travel; it is easy to go through the focal region too quickly to see it; and the documentation makes no mention of it. People may think the higher magnification is obtained by zooming in digitally on your computer screen, without realizing that the microscope focuses with high magnification itself. You’ll need to turn on the LED illumination for the 400x scale to get an image. (There are eight white LEDs that provide good even illumination, not four as advertised.)Zooming:As well as these two focus regimes, there is a software zoom option. If you choose a capture size of 640×480 you can go to the preferences menu and choose zoom to zoom in digitally. The field of view zooms from 13.5mm down to 4.2 mm.Measuring actual magnification:The 20x and 400x are only approximage values, but you can measure the actual magnification by viewing a millimeter ruler or finer reticule if you have one. If the image capture size is set to 1280×960, I find that the width of the field of view is 13.5 mm at the “20x” focus, and about 0.8 mm at the “400x” focus. (about a 17x difference) The resolution, that is, the size of a single pixel in the field of view, is 13.5mm/1280= 10.5 microns for the “20x” focus, and 0.8mm/1280=0.6 micron for the “400x” focus. (Of course, the optics aren’t perfect, and it appears to me that at the “400x” focus the optical resolution is about 3 pixels, that is, the smallest features you can see are about 2 micron in size. The magnification you see on your computer screen depends on the screen pixel size, also called the pixel pitch. Mine is 0.282 mm (or 90 pixels per inch, most LCD screens are 90-100 pixels/in.). For my screen, the two actual magnifications are then, 1280*0.282mm/13.5mm = 26.7x and 1280*.282mm/0.8mm = 451x. This is for viewing on the computer screen at “actual size”, not zooming in.Measuring object sizes:The software allows you to measure objects with rulers you can draw over a picture, but you need to enter the actual magnification to calibrate the software ruler. They suggest you take that reading from the scale on the microscope, but there’s so much up and down play in the focus drum… Read more Help other customers find the most helpful reviews Was this review helpful to you? | Comments (11)
31 of 32 people found the following review helpful I agree with Paul, March 19, 2010 By Math Teacher “Tom” (Texas, USA) – Amazon Verified Purchase(What’s this?) This review is from: Veho VMS-004 Discovery Deluxe USB Microscope with x400 Magnification & Flexi Alloy Stand (Camera) Paul gave a very good review of the product and a great mini-lesson on how to use it.It is a great little toy to play with and is a lot of fun. However, I am a teacher and had hoped to use it in a more serious manner in the classroom. I liked the idea of being able to make on-screen measurements and unfortunately, that is the most lacking feature of the product. With my version of software, I am able to enter in a magnification of 400 while making measurements. It was pretty accurate showing .97 mm for one tic mark on a ruler. I know my degree of accuracy in drawing the line was certainly not within .03 mm so I am happy with the results. The reason I am rating it a 3 is simply because of the difficulty in this measurement process. Because the measurements can only be made at 0 distance (i.e. the object at 0 distance from the end of the clear plastic ring) it limits the types of measurements that can be made. For example the field of view at x20 is about 13mm as Paul points out. If I want to take a picture of anything bigger than a dime (or even a dime) I can’t do so because a dime is 18 mm in diameter and won’t fit in the field of view. If I back off a little bit and refocus, I can get an entire dime in the image, but then I have no means of determining the actual magnification ratio. Because this limits my use in a school lab setting, other than just capturing images and video which in itself is useful, I rate it down to a three. In all fairness, I don’t know the capabilities of competing products such as the high priced pro-scope so they may all work this way.Another issue is the funky stand that comes with it. It is too short and inflexible to be useful. It really needs to be twice as long as it is with a second joint between the two arm segments. This would allow the user to actually position it in usable positions. A snake type stand would be better and I am looking for a trashed desk lamp to convert it into a stand. The base of the stand also needs to be weighted more heavily to keep the scope upright.This is a fun scope to play with but these issues are really aggravating and take away from the true utility of the scope. It is a shame that Veho didn’t take the extra step to make the zoom actually work and to make the stand more robust. It couldn’t have added another $5 or $10 to the price of the product which I would have gladly paid to get a truly useful product.For now, it is fun to play with and I am looking forward to the next generation of USB products.

96 of 109 people found the following review helpful Awesome concept but.., July 22, 2010 By Neal – Amazon Verified Purchase(What’s this?) This review is from: Veho VMS-004 Discovery Deluxe USB Microscope with x400 Magnification & Flexi Alloy Stand (Camera) To start, I already own an $800 microscope that has a magnification of 400x, so I thought I would buy this after reading the magnification just to see how they compare, especially considering the price is so generous. I thought that after plugging it in, the magnification wouldn’t be perfect, but it would at least be ball park. Not even close. In fact, its a down right lie. The maximum magnification that is claimed to be 400x is actually closer to 100x than any of the others I compared it to using the stronger microscope that I have. The clarity under that magnification is between fair and good, but not great. This is a neat piece of equipment, but it really is just a toy. It should not be considered by anyone that actually needs good resolution microscopy with a magnification greater than about 100x.
