New Sigma lens for your Nikon

High resolution images of it may be hard to find but fast images with the new Sigma 70-200mm APO EX DG OS HSM for both Nikon and Canon which will make you quite happy.

New lens for your Nikon

The lens uses two FLD panels which will help it give you a clear image, and it also has three SLD glass plates to help prevent abberation.

Now this lens has a large aperture which means that f2.8 will come in handy with your wildlife, wildflower, and even sports photography. While I would not recommend using this to shoot action on say a football or baseball field, it might work well for hockey, basketball, or other indoor sports.

A New Nikon for Newbies

The newest Nikon, the D3100 against a blue background

Nikon's newest newbie-friendly DSLR

My how time flies. It was only 13 months ago that Nikon announced its new flagship camera designed for beginners, the D3000. It is a 10.2 megapixel camera with an APC chip which excels as being a beginner’s camera. The camera has been overshadowed by its predecessor, the D40, the upper-end D5000 and the even higher priced D90.

Now Nikon has introduced to the world the new D3100. So what has changed? Let’s see…according to the folks at DPReview.com, the new DSLR has four additional megapixels topping out at 14.2 megapixels. This addition means larger file sizes. How big are the new files? Well that purely depends on your format. If you shoot in a raw format, it could make your file sizes a couple of megabytes larger however, it still is nowhere near the 77 megabyte file sizes of the Canon Mark III series.

It has live view which means that you can use the LCD monitor as a viewfinder and compose your image like you do as when you use a point and shoot digital camera.

In many ways this new camera seems to mark the new standards for Nikons updated line for 2010-11. You can bet that many of the same improvements that we see in this camera will make their ways up the line for at least the consumer grade DSLR’s. So this means that I expect to see similar jumps in the D5000 line and maybe even the D90 line however I would not expect to see this in their pro-sumer catagory which, to me anyway, starts with the Nikon D300s which already has most of these upgrades in this $1500 model.

The best part of this camera is that it can shoot videos at 1080p using any of the existing range of Nikon lenses. (You can see the details of those lenses at Nikon.com or at DPReview.com or any other review site). It also has a wonderful new HDMI output so you can plug that camera into your plasma, LED/LCD, or other high definition telelvisions and view your work before editting it or burning it to DVD.

The camera has more than 2 megapixels in quality

Don’t lose your images to a lossy .jpg

Before we being, I apologize for my absence. I’ve switched jobs, switched lives basically and am just now getting settled into some kind of routine. Thanks for sticking with me during the past month of silence.

Okay…so if you’re like me you shoot in raw or maybe jpg and then rush over to your PC to download your shots and view them in some tool like Lightroom, Picasa, Microsoft Paint, whatever…

There is a reason why you should not save those precious images in a .jpg format for long term.

Everytime you open a .jpg type image you decompress the image and when you close it, you recompress it. It’s in this recompression that you wind up losing data. To understand why this happens you have to understand how compression works.

Compression works by using an algorithm to compute where changes in your file can be safely made to substitute one character for several. Now for you techies…this is a major simplification of the process. There is actually a lot that happens but suffice it to say that the original file that you started out with is stored in a compressed format. JPG uses this to reduce the size of the file and there are two formats…lossless and lossy.

If you are using lossy, you are also using a format that loses data. So everytime you open a file in Picasa, Photoshop, John’s photo viewer, etc…you are losing data. So over time, that image of your loved one, pet, flower, or something else over time, and multiple openings and closings, will start showing noticeable signs of deterioration in the digital version.

So what’s the solution? Save images in a lossless .jpg format or save them in an entirely different format like tiff, or maybe even .bmp (yes…a bitmap). Another option is to save original in their raw format that your camera shots them in, and use a lossless .jjpg for sharing and use a tiff/bmp on those images that you want to save for a very long time.

If your images are already in a lossy .jpg format. save them in a different format like tiff now. If you are just now importing images from your camera in a nice raw file mode, leave them in that mode and work with/use .jpg copies for short periods of time. Of course you can always make digital copies of your jpgs and share them.

More about online photo storage

Well I told you a couple of months ago that I would give you some additional information regarding online photo storage and there has been a little movement in the market as prices have come down a little bit and services have become easier to use and access. So let’s review my top five online digital photography storage sites.

First let’s review my criteria for selecting someplace to store your images online:

  1. Provides you with tools to upload multiple images off of your PC/Camera at one time
  2. Provides you with access to your images regardless of platform (PC/Phone/etc)
  3. Provides you with quality service around the clock
  4. Provides you the ability to have backups of your image collection
  5. The service does not automatically resize your images or provides you with tools to restore their original size
  6. The service gives you control over who looks at and downloads your images

With that in mind, here are my top 7 online image hosting services. These are in no particular order. I do this because I want you to go to each site and maybe look up one or two of your own and see which ones you will think can work best for your needs.

  1. Adobe Photoshop.com starts you with 2GB of storage for free but that’s not this site’s strength. Oh no…this site’s strength is in its editting
    tools. These tools allow you to make basic image edits like remove red eye, crop the image, or make some basic changes. For $20/year, you
    can buy 20GB of space. And you can expect to pay $1/GB for each increase above that.
  2. Flickr’s free account provides you with a monthly upload/download limit which has changed and continues to change. For $25/year you get
    unlimited photo and video storage.
  3. Smugmug is service geared at semi-professional and professional photographers. For $40/$60/$150 a year you can have more control over the
    site that presents your images. All plans have unlimited storage and allow you universal access to your images. The high end plan gives you
    complete control over the page that displays your images plus the way you sell your photographs.
  4. Photobucket is an Internet staple. Free accounts get 500 MB of online storage and you are allowed up to 10GB of downloadable bandwidth per
    month. There is a 1MB size limit per photo so if you use a Canon Mark V with the 77MB raw files, this is not going to be the solution for
    you. However for $25 a year, those limitations are removed and you get to post images up to 4000×3000 plus access to their technical support
    team
  5. Webshots by American Greetings, is a service that comes with the ability to use your images or the predefined images of other photographers
    into your projects. What this means is that there is also a likelihood for others to have access to your images for things like calendars, coffee
    mugs, and the like. They give you a 1000 image limit and then boost that with 100 extra images for every month that you remain a member of
    their free plan. For $20/year, those restrictions are limited but this offering is among the least favorable ones for photographers looking to post
    the thousands of images they generate a year.

Now there are some prominent sites that I left out. I left them out for a reason. Either I am not a fan of their policies or I do not like the software they ask the user to use for their site. However everyone is different and I urge you to research these other sites as well.

If you have any additional questions, just ask.
