Social Media and Guest Snapshots

When you think of the memories you’ll have and share of your special day, thoughts of your professionally done wedding portraits should be at the forefront of your mind. What you may not think of immediately is guest snapshots; the in-the-moment pictures your friends and family quickly snap up while shaking a leg on the dance floor. Although these images can be beautiful and full of life, and many argue add a degree of personality to any photo album, they’re not likely to catch your better side or portray your Aunt’s bright yellow party dress in the best lighting conditions. As such, many new couples are searching for alternatives which allow them to choose the first images shared around on their social media platforms like Facebook and Google+.

If this is a concern for you talk to your wedding photographer about social media options. Many photographers, including Piper Studios, offer digital images via DVD, which are easily uploaded to any social media platform. If you’ve chosen your photographer correctly these digital copies will portray the event with more creativity, artistry and more beautifully than anything your guests could tag on their walls. And if making sure you’re the first to upload the photos of your dress isn’t a top priority, there’s still the option of including your guest’s photographs in you professionally built album or DVD. These photos often resonate with the love and affection only friends and family can bring to the camera, and bring a sense of reality to your memories of that one day when you were truly the life of the party.

Additionally, including guests photos will provide more complete coverage of the event, capturing spontaneous moments and guest interactions you may have missed. Many wedding photographers pride themselves on the orchestration of all the visual memories for these special events, often incorporating slideshows, video, and guest photographs in their work. Yet an album put together by your friends and family is another option altogether. Letting your loved ones pick and choose the images they feel best portray the evening, your relationship with your new spouse, or even your relationship with them can give an interesting and unique spin to the wedding album. Consider asking a group of friends, perhaps colleagues or university chums, to put together an album, using your professional photographs and their own, and you’ll be surprised at how thoughtful and personal the results can be. These types of projects produce irreplaceable mementos you’ll cherish for years alongside your professionally done portraits.

Difference Between Photographs And Snapshots

The difference between photography and snapshots is that a photograph contains artistic elements and it has some dependency on the photographer’s technical skills; whilst a snapshot is just a visual record of an object in front of the lens. Nowadays, the cameras has automatic functions that help largely with the technical bits, but the artistic element has to depend on the photographer.

The majority of the pictures taken each year are snapshots, and billions of them are produced annually. Actually snapshots are pretty valuable. They are very meaningful especially to the people who took them, those who are in the shots, and to their relatives, friends and family. Snapshots provide records of wonderful places, people and events, of this planet’s life as seen by people who are living it. A photograph, however, connects with an even wider variety of audience, because it looks nicer artistically, and most of them carry a message, which hits home with a universal truth. In the world of photography, there is still a lot of space for both, although the difference between photographs and snapshots still stands. Basically, there’s absolutely nothing wrong if you liked taking snapshots and is perfectly happy with it.

Whether it is photographs or snapshots, they have a few common elements which you need to know to improve your camerawork. Below are some points for photography for your knowledge.

Firstly, photography has changed from a professional practice to a much easier and portable practice. Nowadays, taking snapshots with a camera is much simplified. Secondly, Photography is a form of art as well. Thirdly, the camera serves as a tool for us. We are the people who make a difference in the shots, whether it is a poorly taken one or a good shot. Lastly, if you practice enough, you can take better photos too, whatever the subject is.

This is the difference between photographs and snapshots. When taking a good photograph, there are a lot of elements to bear in mind. These elements include your method of lighting, whether they are effective, your subjects, whether they are interesting, if not, how you turn them into interesting photographs with your skills. The composition of your shots is an important element as well. Practice makes perfect. With adequate practice, you will be able to produce quality photographs instead of snapshots.

Oracle Snapshot Too Old Intricacies

If you think you can fix oracle error “ORA-01555: snapshot too old” just by increasing the rollback segments, think again as reading this article may potentially alter your opinion.

The article explains the inner details about this oracle error, indicates the possible course of action and provides details on how to fix or avoid this error. It also explains with an example scenario that the best solution for ORA-01555 error is tuning application logic rather than adding more rollback segments.

ORA-01555: snapshot too old: rollback segment number string with name “string” too small.

Cause: rollback records needed by a reader for consistent read are overwritten by other writers.

Action: If in Automatic Undo Management mode, increase undo_retention setting. Otherwise, use larger rollback segments Details: There are number of reasons for the ORA-01555 error. The most common reason is that the rollback segments are too small. Rollback segments are used by the Oracle for reconstructing the read-consistent snapshot of the data. In Oracle during the DML operations for any changes to the data records, a snapshot of the record before the changes were made is copied to a rollback segment.

After transaction completes, its data is not deleted from the rollback segment. It remains there to service the queries and transactions that began executing before it was committed. This may cause problems with long queries because these blocks may be overwritten by other transactions, even though the separate long-running query against those blocks has not completed. So ORA-01555 error may occur whenever a long-running query is executed at the same time as data manipulation transactions.

How to avoid/fix this error :

o Augment the size of all the roll back segments.

o Add more rollback segments.

o Augment the ‘OPTIMAL’ size of the roll back segments.

o Tune the application to “commit” more frequently such that smaller rollback space is used and this condition can be avoided.

o Follow the Oracle recommended ‘proper’ solution: schedule long-running queries at times when online transaction processing is at a minimum.

Example:

ORA-01555 Error Scenario: Sample application logic causing ORA-01555 error:

  • Prepare a select
  • fetchrowArray
  • while the row is not null
  • update the row
  • if nrows mod commitsize then commit
  • fetch the next row
  • end while
  • final commit

This application logic was implemented using Perl, DBD, DBI and oracle. It raised the error as shown below:

DBD::Oracle::st fetchrow_array failed: ORA-01555: snapshot too old: rollback segment number 15 with name “_SYSSMU15$” too small (DBD ERROR: OCIStmtFetch) [for Statement ..]”

Analysis and Resolution:

As you can see from the application logic, the rows selected by the outer select query are being modified by the update statement. ie both are acting on the same table . It can be resolved by setting UNDO_RETENTION appropriately large enough BUT it may not be the best solution.The better solution may be separating out select and updates in to different transactions. After rewriting the application logic by separating data selecti and update activities, the user didn’t experience ORA-01555: snapshot too old error any longer.
